13" Heavy 13 ® Gearhead Lathe

About This Machine Foreword

"

The screw cutting engine lathe is the oldest and most important of machine tools and from it all other machine tools have been developed. It was the lathe that made possible the building of the steamboat, the locomotive, the electric motor, the automobile and all kinds of machinery used in industry. Without the lathe our great industrial progress of the last century would have been impossible.

" —How To Run a Lathe, 15th Edition, South Bend Lathe.

Features

These Heavy 13 ® Gearhead Lathes are packed with standard features and equipment, such as a complete coolant system, easy-to-clean chip drawer, one-shot way lubrication system, included steady and follow rests, chuck guard, adjustable work lamp, foot brake, powered cross feed, 3- and 4-jaw chucks, faceplate, and premium Allen-Bradley contactors, thermal relays, and fuse system.

The lathe represented in this manual is a modern day version of the screw cutting lathes that trace their roots back to the 1700's, which were themselves technological improvements of the bow lathe that can be traced back thousands of years to the ancient Egyptians.

Spindle speeds are controlled by convenient headstock levers, which allow the operator to quickly set the spindle speed within the available range of 80–2000 RPM.

The beds of these lathes are constructed with Meehanite castings that are hardened and precision-ground in the traditional three V-way prismatic design—long used on South Bend Lathes for its accuracy, durability, and rigidity.

Now, almost 300 years later, these modern "screw cutting" lathes are not just a piece of refined machinery, but a culmination of human ingenuity and knowledge embodied into the design and synergy of thousands of interworking parts—some of which represent the life's work and dreams of many inventors, mechanical engineers, and world-class machinists—including the likes of Leonardo da Vinci, Henry Maudsley, and the founders of South Bend Lathe, John and Miles O'Brien.

And now the torch is passed to you—to take the oldest and most important type of machine tool—and carry on the tradition. As the operator of a South Bend Lathe, you now join the ranks of some very famous and important customers, such as Henry Ford, who used the machines he purchased to help him change the world.

The headstocks feature quick-change gear levers and the carriages include an adjustable clutch that disables automatic carriage feed when it contacts the included feed stop or in the event of a crash.

To further ensure a high degree of accuracy, these lathes are equipped with Japanese spindle bearings. The spindles are D1-5 camlock with an MT#5 taper and 1.57" bore. The tailstocks have an MT#3 taper and 4.5" of quill travel.

Capabilities

This Heavy 13 ® Gearhead Lathe is built for daily use in a busy industrial setting. Loaded with many nice features and high-precision parts, this lathe excels at making fine tools, dies, thread gauges, jigs, and precision test gauges—however, it is by no means delicate. Thick castings, heavy weight, and quality construction throughout provide the necessary brawn for demanding production and manufacturing tasks.

Additional Metal Lathe Safety

Speed Rates.

Operating the lathe at the wrong speed can cause nearby parts to break or the workpiece to come loose, which will result in dangerous projectiles that could cause severe impact injuries. Large or non-concentric workpieces must be turned at slow speeds. Always use the appropriate feed and speed rates.

Chuck Key Safety.

A chuck key left in the chuck can become a deadly projectile when the spindle is started. Always remove the chuck key after using it. Develop a habit of not taking your hand off of a chuck key unless it is away from the machine.

Safe Clearances.

Workpieces that crash into other components on the lathe may throw dangerous projectiles in all directions, leading to impact injury and damaged equipment. Before starting the spindle, make sure the workpiece has adequate clearance by hand-rotating it through its entire range of motion. Also, check the tool and tool post clearance, chuck clearance, and saddle clearance.

Clearing Chips.

Metal chips can easily cut bare

skin—even through a piece of cloth. Avoid clearing chips by hand or with a rag.

Use a brush or vacuum to clear metal chips.

Stopping Spindle by Hand.

Stopping the spindle by putting your hand on the workpiece or chuck creates an extreme risk of entanglement, impact, crushing, friction, or cutting hazards. Never attempt to slow or stop the lathe spindle with your hand. Allow the spindle to come to a stop on its own or use the brake.

Crashes.

Aggressively driving the cutting tool or other lathe components into the chuck may cause an explosion of metal fragments, which can result in severe impact injuries and major damage to the lathe. Reduce this risk by releasing automatic feeds after use, not leaving lathe unattended during operation, and checking clearances before starting the lathe. Make sure no part of the tool, tool holder, compound rest, cross slide, or carriage will contact the chuck during operation.

Long Stock Safety.

Long stock can whip violently if not properly supported, causing serious impact injury and damage to the lathe. Reduce this risk by supporting any stock that extends from the chuck/headstock more than three times its own diameter. Always turn long stock at slow speeds.

Securing Workpiece.

An improperly secured workpiece can fly off the lathe spindle with deadly force, which can result in a severe impact injury. Make sure the workpiece is properly secured in the chuck or faceplate before starting the lathe.

Chucks.

Chucks are very heavy and difficult to grasp, which can lead to crushed fingers or hands if mishandled. Get assistance when handling chucks to reduce this risk. Protect your hands and the precision-ground ways by using a chuck cradle or piece of plywood over the ways of the lathe when servicing chucks. Use lifting devices when necessary.

Coolant Safety.

Coolant is a very poisonous biohazard that can cause personal injury from skin contact alone, especially when it gets old or has been well-used. Incorrectly positioned coolant nozzles can splash on the operator or the floor, resulting in skin exposure or a slipping hazard. To decrease your risk, change coolant regularly and position the nozzle where it will not splash or end up on the floor.

Tool Selection.

Cutting with an incorrect or dull tool increases the risk of accidental injury due to the extra force required for the operation, which increases the risk of breaking or dislodging components that can cause small shards of metal to become dangerous projectiles. Always select the right cutter for the job and make sure it is sharp. Using a correct, sharp tool decreases strain and provides a better finish.

-14-


S A F E T Y


Additional Chuck Safety

Entanglement.

Entanglement with a rotating chuck can lead to death, amputation, broken bones, or other serious injury. Never attempt to slow or stop the lathe chuck by hand, and always roll up long sleeves, tie back long hair, and remove any jewelry or loose apparel BEFORE operating.

Chuck Capacity.

Avoid exceeding the capacity of the chuck by clamping an oversized workpiece. If the workpiece is too large to safely clamp with the chuck, use a faceplate or a larger chuck if possible. Otherwise, the workpiece could be thrown from the lathe during operation, resulting in serious impact injury or death.

Chuck Speed Rating.

Excessive spindle speeds greatly increase the risk of the workpiece or chuck being thrown from the machine with deadly force. Never use spindle speeds faster than the chuck RPM rating or the safe limits of your workpiece.

Using Correct Equipment.

Many workpieces can only be safely turned in a lathe if additional support equipment, such as a tailstock or steady rest, is used. If the operation is too hazardous to be completed with the lathe or existing equipment, the operator must have enough experience to know when to use a different machine or find a safer way. If you do not have this experience, seek additional training (outside of this manual) from experienced lathe operators, books, or formal classes

Clamping Force.

Inadequate clamping force can lead to the workpiece being thrown from the chuck and striking the operator or bystanders. Maximum clamping force is achieved when the chuck is properly maintained and lubricated, all jaws are fully engaged with the workpiece, and the maximum chuck clamping diameter is not exceeded.

Proper Maintenance.

maintained and lubricated to achieve maximum clamping force and withstand the rigors of centrifugal force. To reduce the risk of a thrown workpiece, follow all maintenance intervals and instructions in this document.

All chucks must be properly

Trained Operators Only.

Using a chuck incorrectly can result in workpieces coming loose at high speeds and striking the operator or bystanders with deadly force. To reduce the risk of this hazard, read and understand this document and seek additional training from an experienced chuck user before using a chuck.

Disconnect Power.

procedures.

Serious entanglement or impact injuries could occur if the lathe is started while you are adjusting, servicing, or installing the chuck. Always disconnect the lathe from power before performing these -15-

Power Supply Requirements Availability

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed.

To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrician or qualified service personnel in accordance with all applicable codes.

Serious injury could occur if you connect the machine to power before completing the setup process. DO NOT connect to power until instructed later in this manual.

Full-Load Current Rating

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

SB1049 Full-Load Rating ................ 19.5 Amps SB1050 Full-Load Rating ................ 19.5 Amps

For your own safety and protection of property, consult an electrician if you are unsure about wiring practices or applicable electrical codes.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result—especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the requirements in the following section.

Circuit Requirements

This machine is prewired to operate on a 220V power supply circuit that has a verified ground and meets the following requirements:

Nominal Voltage ............................... 220V/240V Cycle .............................................................60 Hz Phase ..............................................Single-Phase Circuit Rating....................................... 30 Amps Cord ........."S" Type, 3-Wire, 12 AWG, 300 VAC Plug/Receptacle ............................NEMA L6-30

A power supply circuit includes all electrical equipment between the main breaker box or fuse panel in your building and the incoming power connections inside the machine. This circuit must be safely sized to handle the full-load current that may be drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

Note: The circuit requirements in this manual

are for a dedicated circuit—where only one machine will be running at a time. If this machine will be connected to a shared circuit where multiple machines will be running at the same time, consult a qualified electrician to ensure the circuit is properly sized.

-17-




Grounding Requirements

This machine must be grounded! In the event of certain types of malfunctions or breakdowns, grounding provides a path of least resistance for electric current in order to reduce the risk of electric shock.

Extension Cords

We do not recommend using an extension cord with this machine. If you must use an extension cord, only use it if absolutely necessary and only on a temporary basis.

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord is necessary, do not connect the equipment grounding wire to a live (current carrying) terminal.

Check with an electrician or qualified service personnel if you do not understand these grounding requirements, or if you are in doubt about whether the machine is properly grounded. If you ever notice that a cord is damaged or worn, disconnect it from power, and immediately replace it with a new one.

The power cord and plug specified under Circuit

Requirements section on the previous page has

an equipment-grounding wire and a grounding prong. The plug must only be inserted into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances (see Figure 9).

Extension cords cause voltage drop, which may damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size get smaller (higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must contain a ground wire, match the required plug and receptacle, and meet the following requirements: Minimum Gauge Size ............................... 12 AWG Maximum Length (Shorter is Better) ........... 50 ft.

Cleaning & Protecting

The unpainted surfaces are coated at the factory with a heavy-duty rust preventative that prevents corrosion during shipment and storage. The benefit of this rust preventative is that it works very well. The downside is that it can be time-consuming to thoroughly remove.

Be patient and do a careful job when cleaning and removing the rust preventative. The time you spend doing this will reward you with smooth-sliding parts and a better appreciation for the proper care of the unpainted surfaces.

Although there are many ways to successfully remove the rust preventative, the following process works well in most situations.

Before cleaning, gather the following:

• Disposable rags • Cleaner/degreaser (certain citrus-based degreasers work extremely well and they have non-toxic fumes) • Safety glasses & disposable gloves

Note:

Automotive degreasers, mineral spirits, or WD•40 can be used to remove rust preventative. Before using these products, though, test them on an inconspicuous area of a painted surface to make sure they will not damage it.


Avoid chlorine-based solvents, such as acetone or brake parts cleaner that may damage painted surfaces. Always follow the manufacturer’s instructions when using any type of cleaning product.

Basic steps for removing rust preventative:

1.

Put on safety glasses and disposable gloves.

2.

Coat all surfaces that have rust preventative with a liberal amount of your cleaner or degreaser and let them soak for a few minutes.

3.

Wipe off the surfaces. If your cleaner or degreaser is effective, the rust preventative will wipe off easily.

Note:

To clean off thick coats of rust preventative on flat surfaces, such as beds or tables, use a PLASTIC paint scraper to scrape off the majority of the coating before wiping it off with your rag. (Do not use a metal scraper or it may scratch the surface.)

4.

Repeat Steps 2–3 as necessary until clean, then coat all unpainted surfaces with a quality metal protectant or light oil to prevent rust.

GAS

Gasoline and petroleum products have low flash points and can explode or cause fire if used for cleaning. Avoid using these products to remove rust preventative.

Remove the end gear cover and end gears, and use a stiff brush with mineral spirits to clean the rust preventative from the gears and shafts. DO NOT get any cleaner or rust preventative on the V-belts, as it could damage them or make them slip during operations. If the belts do become contaminated, replace them.

Many cleaning solvents are toxic if inhaled. Minimize your risk by only using these products in a well ventilated area.

-20-



Location Physical Environment

The physical environment where your machine is operated is important for safe operation and longevity of parts. For best results, operate this machine in a dry environment that is free from excessive moisture, hazardous or flammable chemicals, airborne abrasives, or extreme conditions. Extreme conditions for this type of machinery are generally those where the ambient temperature is outside the range of 41°– 104°F; the relative humidity is outside the range of 20–95% (non-condensing); or the environment is subject to vibration, shocks, or bumps.

Electrical Installation

Place this machine near an existing power source. Make sure all power cords are protected from traffic, material handling, moisture, chemicals, or other hazards. Make sure to leave access to a means of disconnecting the power source or engaging a lockout/tagout device.

Lighting

Lighting around the machine must be adequate enough to perform operations safely. Shadows, glare, or strobe effects that may distract or impede the operator must be eliminated.


Weight Load

Refer to the Machine Specifications for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.

Space Allocation

Consider the largest size of workpiece that will be processed through this machine and provide enough space around the machine for adequate operator material handling or the installation of auxiliary equipment. With permanent installations, leave enough space around the machine to open or remove doors/covers as required by the maintenance and service described in this manual.

Children or untrained people may be seriously injured by this machine. Only install in an access restricted location.

Lifting & Moving



5.

Position hardwood blocks under each end

of the bed as shown in Figure 13. This will keep the lifting straps away from the leadscrew, feed rod, and spindle rod to prevent bending them during lifting.

(Looking at Lifting Setup from Tailstock End)

To Power Lifting Equipment Leadscrew Lifting Strap Feed Rod Control Rod Lathe Bed

This machine and its parts are heavy! Serious personal injury may occur if safe moving methods are not used. To reduce the risk of a lifting or dropping injury, ask others for help, and use power equipment and guide rods.

Do not attempt to lift or move this lathe without using the proper lifting equipment (such as forklift or crane) or the necessary assistance from other people. Each piece of lifting equipment must be rated for at least 25% more than the shipping weight of your lathe to support dynamic loads that may be applied while lifting. Refer to

Things You'll Need on Page 16 for details.

Hardwood Blocks and Planks Positioned as Required to Prevent Lifting Straps from Bending Leadscrew

Figure 13. Lifting setup to keep straps from bending leadscrew or rods.

Note:

Fasten a center support between the hardwood blocks so that they will stay spread apart and in place when lifting (see the example in Figure 14).

To lift and move the lathe: 1.

Remove the shipping crate top and sides,

then remove the small components from the shipping pallet.

Center Support

2.

Move the lathe to its prepared location while it is still attached to the shipping pallet.

3.

Unbolt the lathe from the shipping pallet Hardwood Blocking

4.

To balance the load for lifting, move the tailstock and carriage to the extreme right end of the bedway, then lock them in place.

Note:

Before attempting to move the carriage, make sure the carriage lock is loose, the half nut is disengaged, and the power feed is disengaged (feed selection lever).

Leveling & Mounting

You must level your machine and either use the included foot pads and leveling hardware or bolt and shim your lathe to the floor. Because mounting your lathe to the floor with permanent hardware is an optional step and floor materials may vary, floor mounting hardware is not included.

Leveling

Hardwood Blocking Hardwood Blocking

Figure 15. Example of lathe setup for lifting.

7.

At each end of the lathe, have assistants connect guide rods to safely keep the lathe from swaying or tipping during lifting.

For accurate turning results and to prevent warping the cast iron bed and ways, the lathe bedways MUST be leveled from side-to-side and from front-to-back on both ends.

Re-check the bedways 24 hours after installation, two weeks after that, and then annually to make sure they remain level.

When lifting the lathe with straps, the load will be top heavy. Take extra care to keep the load balanced vertically and only lift the lathe far enough to remove the shipping pallet.

8.

Raise the lathe a couple of inches and check the balance of the load.

— If the load is not safely balanced, immediately lower the lathe and resolve the issue before attempting to lift it again.

9.

Raise the lathe enough to clear the shipping pallet, carefully remove the pallet, then lower the lathe into position.

Leveling machinery helps precision components, such as bedways, remain straight and flat during the lifespan of the machine. Components on a machine that is not level may slowly twist due to the dynamic loads placed on the machine during operation.

For best results, use a precision level that is at least 12" long and sensitive enough to show a distinct movement when a 0.003" shim (approximately the thickness of one sheet of standard newspaper) is placed under one end of the level.

See the figure below for an example of a high precision level.

Figure 16. Example of a precision level.

-23-



To level the machine, use a precision level to make sure the bedways are level from side-to side and from front-to-back.

— If using the included leveling pads (see

Figure 17), place them under the six

leveling jack bolt locations, then adjust the bolts to level the lathe.


Assembly

With the exception of the handwheel handles, the lathe is shipped fully assembled.

To install the handwheel handles, thread the large handle into the carriage handwheel and the small handle into the cross slide handwheel, as shown in Figure 19.

Jack Bolts Pads Figure 17. Leveling pads and screws.

— If using mounting hardware that does not allow for adjustment, level the lathe by placing metal shims between the lathe base and the floor before bolting it down.

Bolting to Concrete Floors

Lag screws and anchors, or anchor studs (below), are two popular methods for bolting machinery to a concrete floor. We suggest you research the many options and methods for mounting your machine and choose the best one for your specific application.

Handwheel Handles Figure 19. Handwheel handles installed.

Lubricating Lathe

GEARBOXES MUST BE FILLED WITH OIL!

Anchor Stud OIL MAY NOT BE SHIPPED WITH MACHINE!

Refer to Lubrication Section for Correct Oil Type.

Lag Screw and Anchor Figure 18. Common types of fasteners for bolting machinery to concrete floors.

Most electrical codes require that machines connected to the power source by fixed conduit MUST be secured to the floor.

The headstock, quick-change gearbox, and apron oil reservoirs must have the proper amount of oil in them before the lathe can be operated for the first time.

Damage caused to the bearings and gears from running the lathe without oil in the reservoirs will not be covered under warranty. Refer to the

Lubrication section, beginning on Page 66, for

details on how to check, add oil, and prime the headstock oil pump.

Refer to the V-Belts subsection on Page 77 for detailed instructions.

-29-



Spindle Break-In

Before subjecting the lathe to full loads, it is essential to complete the spindle break-in process as described below. This will ensure the best results and maximum life of the precision components inside the lathe.

The break-in procedure must be performed in succession with the Test Run procedure described in this manual, because many of the test run steps prepare the lathe controls for the break-in process.

Important: Do not perform the break-in

procedure independently from the Test Run section—serious damage could occur to the lathe if the controls are set differently than instructed in that section.


4.

Use the foot brake to stop spindle rotation, then run the lathe at 200 RPM for 10 minutes with the gearbox range lever on the headstock in the lever in the

H L

(low) position, and then run the lathe another 10 minutes with the (high) position.

5.

While the oil is still warm and any metal particles are still suspended in the oil, change the headstock and gearbox oil (refer to Lubrication beginning on Page 66 for detailed instructions).

6.

Check the V-belt tension, and if necessary, re-tension them (refer to V-Belts on Page

77 for detailed instructions).

Congratulations! The spindle break-in is complete.

Do not leave the lathe unattended during the Spindle Break-In procedure. If your attention is needed elsewhere during this procedure, stop the lathe and restart the procedure later from the beginning.

To perform the spindle break-in:

1.

Successfully complete the Test Run procedure beginning on Page 26.

2.

Using the spindle speed levers to set the spindle speed, run the lathe for 10 minutes at each of the spindle speeds starting with the lowest speed.

Note:

If necessary, refer to Setting Spindle

Speed on Page 50 for detailed instructions.

3.

Use the foot brake to stop spindle rotation, set the spindle speed at 2000 RPM, then use the spindle lever to reverse the spindle rotation and run the lathe for 10 minutes.

Chuck & Faceplate Mounting


This lathe is equipped with a D1-type spindle nose. This type of spindle uses camlocks that are adjusted with a chuck key to securely mount a chuck or faceplate with repeatable precision and ease.


Installation & Removal Devices

Because chucks are heavy and often awkward to hold, some kind of lifting, support, or protective device should be used during installation or removal. The weight and size of the chuck will determine the appropriate device to use (refer to the following figure for examples).

Never use spindle speeds faster than the chuck RPM rating or the safe limits of your workpiece. Excessive spindle speeds greatly increase the risk of the workpiece or chuck being thrown from the machine with deadly force!

This lathe ships with the 3-jaw chuck installed. This is a scroll-type chuck where all three jaws move in unison when the chuck key is used.

The included 4-jaw chuck features independent jaws, which are used for square or unevenly shaped stock, and to mount work that needs to be adjusted to near zero total indicated runout.

If neither chuck can hold your workpiece, the cast iron faceplate has slots for T-bolts that hold standard or custom clamping hardware. With the correct clamping hardware, a faceplate offers a wide range of uses, including machining non concentric workpieces, straight turning between centers, off-center turning, and boring.

A dropped chuck can cause amputation, serious crushing injuries, or property damage. Always use a lifting, support, or protective device to reduce this risk when installing or removing a chuck.

Chuck Installation

To ensure accurate work, it is extremely important to make sure the spindle nose and chuck mating surfaces/tapers are clean. Even a small amount of lint or debris can affect accuracy.

The chuck is properly installed when all camlocks are tight, the spindle and chuck tapers firmly lock together, and the back of chuck is firmly seated against the face of the spindle all the way around—without any gaps.


5.

Incrementally tighten the camlocks in a criss-cross or star pattern to ensure that the chuck seats evenly against the spindle.

6.

When the chuck is fully seated and all the

camlocks are tight, verify that the cam line is between the two "V" marks on the spindle nose, as shown in the following figure.

To install the chuck:

1.

DISCONNECT LATHE FROM POWER!

2.

Use an appropriate lifting, support, or protective device to protect the ways and support the chuck during the installation process.

3.

Clean and lightly oil the camlock studs, then thoroughly clean the mating surfaces of the spindle and chuck.

4.

Install the chuck by inserting the camlock studs straight into the spindle cam holes.

Important: Avoid inserting the studs by

pivoting them in from an angle or rotating the spindle. This can damage studs or spindle cam holes.

Cam line between “V”s

Figure 30. Cam line positioned between the "V" marks after the camlocks are fully tightened.

— If the cam line is NOT between the "V" marks when the camlock is tight, the stud may be installed at the incorrect height. To fix this, adjust the stud height as shown in the following figure. Make sure to re-install the stud cap screw afterward.

— If adjusting the stud height does not correct the problem, try swapping stud positions on the chuck.

CORRECT INCORRECT INCORRECT

Stud Too High: Turn In One-Turn

INCORRECT

Stud Too Low: Turn Out One-Turn

Figure 29. Inserting camlock studs into spindle cam holes.

Figure 31. Correcting an improperly installed stud.

-33-




7.

Verify that the chuck fits the spindle properly by checking for any gaps between the mating surfaces.

— If there are no gaps, proceed to Step 8.

— If there is a gap, remove the chuck, re clean the mating surfaces carefully, and re-install. If the problem persists, contact our Tech Support.

8.

Verify that the chuck/spindle tapers are seated firmly together by removing the chuck, per the Chuck Removal instructions, and pay close attention to how easily the tapers release.

— If it was necessary to bump the chuck or use a mallet to release the tapers, then they are seating together properly.

— If the tapers released easily with little intervention, they are not seated together firmly as required. Remove the chuck, re clean the mating surfaces carefully, and re-install. If the problem persists, contact our Tech Support.

Chuck Removal To remove the chuck:

1.


2.

Use an appropriate lifting, support, or protective device to protect the ways and support the chuck (refer to Installation &

Removal Devices on Page 32).

3.

Loosen the camlocks by turning the key counterclockwise until each of the cam lines are aligned with its corresponding spindle mark (see Figure 33).

Cam line aligned with spindle mark

Registration Marks

Lightly stamp registration marks across the mating seams of chuck components. These marks will help you re-install the chuck in the same position after removal, which ensures consistent chuck balance and turning results, and allows the same camlocks and studs to operate together for consistent locking and unlocking.

Camlock Spindle Spindle & Chuck Registration Marks Chuck Halves Marks for Chuck Reassembly 2-Piece Direct Mount Camlock Chuck

Figure 32. Registration mark locations.

Figure 33. Camlock is fully loosened when the cam line is aligned with the spindle mark.

Tip:

Camlocks can become very tight. A cheater pipe may be used as a last resort to add leverage when loosening. After loosening, you may need to wiggle the chuck key in the camlock to fully disengage the stud.

4.

Using a dead blow hammer or other soft mallet, lightly tap around the outer circumference of the chuck body to loosen it from the spindle.

5.

Remove the chuck from the spindle, using a light rocking motion to carefully slide the studs out of the cam holes.

— If the chuck does not immediately come off, rotate it approximately 60° and tap it again. Make sure all the marks on the cams and spindle are in proper alignment for removal.

-34-




Scroll Chuck Clamping

This scroll-type chuck has an internal scroll-gear that moves all jaws in unison when adjusted with the chuck key. This chuck will hold cylindrical parts on-center with the axis of spindle rotation and can be rotated at high speeds if the workpiece is properly clamped and balanced.

Never mix jaw types or positions to

accommodate an odd-shaped workpiece.

The chuck will spin out of balance and may throw the workpiece! Instead, use an independent jaw chuck or a faceplate.

4-Jaw Chuck

Refer to the Chuck Installation (see Page 33) and Chuck Removal (see Page 34) instructions to install or remove the 4-jaw chuck.

The 4-jaw chuck features independently adjustable hardened steel jaws for holding non concentric or off-center workpieces. Each jaw can be independently removed from the chuck body and reversed for a wide range of work holding versatility.

Bar Stock Unstable Workpiece

Because of the dynamic forces involved in machining a non-concentric or off-center workpiece, always use a low spindle speed to reduce risk of the workpiece coming loose and being thrown from the lathe, which could cause death or serious personal injury.

Workpiece Center Point For Machines Mfg. Since 5/11

Faceplate

Refer to the Chuck Installation (see Page 33) and Chuck Removal (see Page 34) instructions to install or remove the faceplate.

The faceplate included with your lathe can be used for a wide range of operations, including machining non-concentric workpieces, straight turning between centers, off-center turning, and boring.

The tools needed for mounting a workpiece will vary depending on the type of setup you have.

4 2 Figure 35. 4-jaw tightening sequence.

6.

After the workpiece is held in place by the jaws, use a dial indicator to make sure the workpiece is centered in the chuck.

— If the workpiece is not correctly centered, make fine adjustments by slightly loosening one jaw and tightening the opposing jaw until the workpiece is correctly positioned (see Figure 36 for an example).

Machining non-concentric workpieces at a high speed could cause the workpiece to be thrown from the spindle with deadly force at the operator or bystanders. To reduce this risk, only machine non-concentric workpieces at low speeds and clamp counter-weights to the faceplate to balance it.

Failure to properly secure a workpiece to the faceplate could cause the workpiece to be thrown from the lathe with deadly force at the operator or bystanders. Use a minimum of THREE independent clamping devices to hold the workpiece onto the faceplate. Figure 36. Example photo of non-cylindrical workpiece correctly mounted on the 4-jaw chuck.

-36-




To mount a non-concentric workpiece to the faceplate:

1.


2.

Protect the bedway with a piece of plywood.

3.

With help from another person or a holding device to support the workpiece, position it onto the faceplate and clamp it in place with a minimum of three independent clamping devices (see Figure 37 for an example).

Be sure to take into account the rotational and cutting forces that will be applied to the workpiece when clamping it to the faceplate. If necessary, use counter-weights to balance the assembly and use a dial indicator to make sure that the workpiece is properly positioned for your operation.

Non-Cylindrical Workpiece Faceplate Figure 37. Example photo of workpiece clamped in a faceplate.

Tailstock

Clamp

The tailstock (see Figure 38) is typically used to support long workpieces by means of a live or dead center (refer to Centers on Page 41). It can also be used to hold a drill or chuck to bore holes in the center of a part. Custom arbors and tapers can also be cut on your lathe by using the offset tailstock adjustment.

Installing Tooling

This tailstock uses a quill with an MT#5 taper that has a lock slot in the back of the bore that accepts tang arbors and drill bits (see Figures

39–40 for examples).

Solid End Open End Figure 39. Types of tapered arbors and tooling.

Tang Solid End Screw End O P E R A T I O N Tang

For Machines Mfg. Since 5/11 However, other tooling without tangs, such as the four remaining tools shown in Figure 39, can still be used if the potential load will not exceed the strength of the tapered fit. For example, this includes smaller drill chucks, drill bits, and centers.

Note:

If the tooling has an open hole in the end but is too short to be exposed in the drift slot for removal, then a screw can be threaded into the end of the tool to provide a solid surface for the quill pin to push against when the quill is retracted for tool removal. Otherwise, removal of such tooling may be difficult.

To install tooling in the tailstock:

1.

With the tailstock locked in place, unlock the quill, then use the handwheel to extend it approximately 1".

2.

Thoroughly clean and dry the tapered mating surfaces of the quill and the center, making sure that no lint or oil remains on the tapers.

Note:

If the tapered tool shaft has a tang, align it with the slot in the back of the quill before seating it.

3.

With a firm and quick motion, insert the tool into the quill. Check to see if it is firmly seated by attempting to twist it—a firmly seated tool will not twist.

4.

Unlock the tailstock and move it until the tip of the tool is close to, but not touching, the workpiece, then re-lock the tailstock.

5.

Start spindle rotation, unlock the quill, then turn the quill handwheel clockwise to feed the tool into the workpiece.

Figure 40. Example photos of inserting MT#5 tools with tangs into the tailstock.

-38-




Removing Tooling

1.

Use a shop rag to hold the tool.

2.

Rotate the quill handwheel counterclockwise until the tool is forced out of the quill.

— If the tool does not come loose by retracting the quill, extend the quill and use a drift key in the slot shown in

Figure 41 to remove the tool.

To offset the tailstock:

1.

Loosen the hex bolts underneath both ends of the tailstock to release the clamping pressure between the top and bottom castings (see Figure 42).

Adjustment Set Screw (1 of 2) Drift Key Slot Offset Indicator Hex Bolt (1 of 2) Figure 41. Drift key slot in the side of the quill.

Offsetting Tailstock

The tailstock can be offset from the spindle centerline for turning tapers. Move the tailstock top casting toward the front of the lathe to machine a taper at the tailstock end. Conversely, position the tailstock top casting toward the back of the lathe to machine a taper at the spindle end.

Note:

The marks on the offset indicator are arbitrary. For a precise offset, use a dial indicator to check quill movement while adjusting the screws.

Aligning Tailstock to Spindle Centerline

This is an essential adjustment that should be verified or performed each time the tailstock is used to turn concentric workpieces between centers or immediately after offsetting the tailstock when turning a taper. If the tailstock is not aligned with the spindle centerline when it is supposed to be, turning results will be inaccurate along the length of the workpiece.

Note:

As long as this dead center remains in the

chuck, the point of the center will remain true to the spindle centerline. The point will have to be refinished whenever the center is removed and then returned to the chuck.

4.

Install a center in the tailstock.

5.

Attach a lathe dog to the test stock from

Step 2, then mount it between the centers

(see Figure 45 for an example).

To align the tailstock to the spindle centerline: 1.

Use the precision level to make sure the bedway is level from side-to-side and from front-to-back.

— If the bedway is not level, correct this condition before continuing with this procedure (refer to Leveling &

Mounting on Page 23).

2.

Center drill both ends of one piece of round stock, then set it aside for use in

Step 5.

3.

Use the other piece of round stock to make a dead center, and turn it to a 60° point, as illustrated in Figure 44.

Figure 45. Example photo of stock mounted between the centers.

6.

Figure 44. Turning a dead center.




Note:

If necessary in the following step, refer

to Offsetting

Tailstock on Page 39 for

detailed instructions.

8.

Use calipers to measure both ends of the workpiece.

— If the test stock is

thicker

at the tailstock end, move the tailstock toward the

front

of the lathe 1 ⁄ 2 the distance of the amount of taper (see Figure 46).

Centers

Figure 48 shows the MT#5 dead centers

included with the lathe. In addition, an MT#7– MT#5 tapered spindle sleeve is included for mounting centers in the spindle.

Dead Center

Move the tailstock toward the front of the lathe ½ the distance of the taper.

Carbide Tipped Dead Center Adapter Sleeve Figure 48. Adapter sleeve and dead centers.

Looking down from above.

Figure 46. Adjust tailstock toward the operator.

Dead Centers

A dead center is a one-piece center that does not rotate with the workpiece and is used to support long, slender workpieces — If the test stock is

thinner

at the tailstock end, move the tailstock toward the

back

of the lathe 1 ⁄ 2 the distance of the amount of taper (see Figure 47).

Looking down from above.

Use the dead center in the spindle for operations where the workpiece rotates with the center and does not generate friction.

The carbide-tipped dead center can better withstand the effects of friction and is best used in the tailstock where the workpiece will rotate against it. The tip of the center must be generously lubricated during the operation to avoid premature wear and maximize smooth operation. Using low spindle speeds will also reduce the heat and wear from friction.

Move tailstock toward the back of the lathe ½ the distance of the taper.

Figure 47. Adjust tailstock away from the operator.

9.

Repeat is achieved.

-41-




Live Centers

A live center has bearings that allow the center tip and the workpiece to rotate together; it can be installed in the spindle and the tailstock quill for higher speeds. However, a live center typically does not provide the same level of rigidity as a dead center, and final workpiece accuracy can suffer as a result.

Thoroughly clean and dry the tapered mating surfaces of the spindle bore, adapter sleeve, and the center, making sure that no lint or oil remains on the tapers.

Note:

This will prevent the tapered surfaces from seizing due to operational pressures, which could make it very difficult to remove the center.

3.

Mount a chuck or faceplate onto the spindle, whichever is correct for your operation.

4.

Insert the center into the sleeve, then insert the sleeve into the spindle bore through the chuck or faceplate.

Figure 49 shows an example photo of a

dead center installed in the spindle, using a lathe dog and faceplate for turning between centers.

Removing Center from Spindle

To remove the sleeve and center from the spindle, insert a piece of round bar stock or similar tool through the outboard end (on the left side of the headstock). Have another person hold onto the sleeve and center with a gloved hand or shop rag, then tap the sleeve loose.

To avoid premature wear of the dead center or damage to the workpiece, use low spindle speeds and keep the tip of the dead center mounted in the tailstock well lubricated.

Mounting Center in Tailstock

Either a carbide-tipped dead center or live center can be used in the tailstock. Mounting instructions are the same for both. Figure

50 shows an example photo of a dead center

mounted in a tailstock.

3.

Use the quill handwheel to feed the quill out from the casting approximately 1".

Note:

Do not extend the quill more than 2" or stability and accuracy will be reduced.

4.

Insert the center into the tailstock quill.

5.

Seat the center firmly into the quill during workpiece installation by rotating the quill handwheel clockwise to apply pressure, with the center engaged in the center hole in the workpiece.

Note:

Only apply enough pressure with the tailstock quill to securely mount the workpiece between centers. Avoid overtightening the center against the workpiece, or it may become difficult to remove later, and it will result in excessive friction and heat, which may damage the workpiece and center.

Removing Center from Tailstock

To remove the center from the quill, hold onto it with a gloved hand or shop rag, then rotate the quill handwheel counterclockwise to draw the quill back into the casting until the center releases.

If the center does not come loose by retracting the quill, extend the quill to expose the slot shown in Figure 51, then use a drift key to remove the center.

Mounting Workpiece Between Centers

2.

Drill center holes in both ends of the workpiece.

3.

Install a dead center in the spindle with a lathe dog and a chuck or faceplate, then install a live center or carbide-tipped dead center in the tailstock.

4.

Lubricate the workpiece center holes, then mount the workpiece between the centers and hold it in place with light pressure from the tailstock center.

5.

Seat the center firmly into the quill by rotating the quill handwheel clockwise to apply pressure against the workpiece (see the example in

Figure 52).

Only apply enough pressure to securely mount the workpiece between centers. Avoid over-tightening the center against the workpiece, or it may become difficult to remove later. Also, over-tightening will result in excessive friction and heat, which may damage the workpiece or center.

To install and use the steady rest: 1.


2.

Thoroughly clean all mating surfaces, then place the steady rest base on the bedways so the triangular notch fits over the bedway prism.

3.

Position the steady rest where required to properly support the workpiece, then tighten the hex nut shown in Figure 53 to secure it in place.

Figure 54. Workpiece mounted in the steady rest.

5.

Loosen the three leaf screws so the finger roller positions can be adjusted.

6.

Use the finger adjustment knobs to position the bottom two finger rollers against the workpiece, as shown in the example of

Figure 54.

7.

Close the steady rest, then use the finger adjustment knobs to adjust all three finger rollers so that they just touch the workpiece without causing deflection.

Note:

The finger rollers should properly support

the workpiece along the spindle centerline while still allowing it to freely rotate.

8.

Tighten the three leaf screws to secure the settings.

-44-



Follow Rest

The follow rest mounts to the saddle with two cap screws (see Figure 55). It is used on long, slender parts to prevent workpiece deflection from the pressure of the cutting tool during operation. Adjust the follow rest fingers in the same manner as the those on the steady rest.

Note:

To reduce the effects of friction, lubricate the brass finger tips with generous lubricant during operation.

Carriage & Slide Locks

The carriage, cross slide, and compound rest have locks that can be tightened to provide additional rigidity during operation, especially during heavy cuts or close tolerance work.

See Figures 56–57 to identify the locations of the locks for each device.

Rotate the rest to the desired angle, as indicated by the scale at the base, then retighten the two hex nuts.

Tip:

The first time you set the angle of the compound rest for cutting threads, mark the location on the cross slide as a quick reference point. This will allow you to quickly return the compound rest to that exact angle the next time you need to cut threads.

Figure 59. Example of tool mounted in tool post.

Over-extending a cutting tool from the post will increase the risk of tool chatter, breakage, or tool loosening during operation, which could cause metal pieces to be thrown at the operator or bystanders with great force. DO NOT extend a cutting tool more than 2.5 times the width of its cross-section (e.g, 2.5 x 0.5" = 1.25").

2.

Firmly secure the cutting tool with at least two tool post bolts.

3.

Check and adjust the cutting tool to the spindle centerline, as instructed in the next subsection.

Aligning Cutting Tool with Spindle Centerline

For most operations, the cutting tool tip should be aligned with the spindle centerline, as illustrated in Figure 60.

Tailstock Center ....................................................1

To align the cutting tool with the tailstock center:

1.

Mount the cutting tool in the tool post, then secure the post so the tool faces the tailstock.

2.

Install a center in the tailstock, and position the center tip near the cutting tool tip.

3.

Lock the tailstock and quill in place.

4.

Adjust the height of the cutting tool so that the tool tip is aligned vertically and horizontally with the center tip, as shown in

Figure 61.

There are a number of ways to check and align the cutting tool to the spindle centerline. If necessary, you can raise the cutting tool by placing steel shims underneath it. The shims should be as long and as wide as the cutting tool to properly support it.

Below are two common methods:

• Align the tip of the cutting tool with a center installed in the tailstock, as instructed on the next page. For this to work, the tailstock must be aligned to the spindle centerline (refer to Aligning Tailstock To Spindle

Centerline on Page 40 for detailed

instructions).

• Make a facing cut on a piece of round bar stock. If the tool is above or below the spindle centerline, a nub will be left in the center of the workpiece. Adjust the height of the tool, then repeat the facing cut to check the adjustment. Repeat as necessary until the center of the workpiece face is smooth.

Adjustable Feed Stop

Use the adjustable feed stop collar (shown in

Figure 62) to set the location where the carriage

should disengage from power feed.

When the apron stop plate contacts the stop collar during an operation that uses the feed rod, the clutch disengages the carriage from the feed rod and movement stops.

Stop Plate

Micrometer Stop

The micrometer stop allows you to stop the carriage at the same position for repeat cuts, such as when turning up to a shoulder. The micrometer stop includes a graduated dial that allows you to precisely position the stop.

The micrometer stop is only designed to be used when feeding the carriage by hand—it should not be used as a stop for power feed or threading operations, because this lathe is not equipped with an automatic feed clutch.

Stop Collar Apron Figure 62. Adjustable feed rod stop collar.

The adjustable feed stop system is designed to stop longitudinal carriage movement at the desired location ONLY when the carriage is engaged with the feed rod.

When the carriage is engaged with the leadscrew for threading operations, the adjustable feed stop system WILL NOT stop carriage movement—you must use the half nut lever instead. Otherwise, the carriage can crash into the chuck, or if it contacts the stop, the leadscrew shear pin will break.

Before doing any threading operation, make sure to loosen the feed stop collar so it slides freely on the feed rod and will not interfere with carriage travel.

The carriage stop on this lathe will NOT automatically stop the carriage during power feed or threading operations when the carriage is engaged with the leadscrew! Failure to heed this notice could result in the carriage crashing and causing severe machine or property damage.

Manual Feed

The handwheels shown in Figure 64 allow the operator to manually move the cutting tool.

Cross Slide Handwheel Carriage Handwheel Compound Rest Handwheel

Spindle Speed

Using the correct spindle speed is important for safe and satisfactory results, as well as maximizing tool life.

To set the spindle speed for your operation, you will need to: 1) Determine the best spindle speed for the cutting task, and 2) configure the lathe controls to produce the required spindle speed.

Determining Spindle Speed

Many variables affect the optimum spindle speed to use for any given operation, but the two most important are the recommended cutting speed for the workpiece material and the diameter of the workpiece, as noted in the formula shown in

Figure 65.

Figure 64. Carriage Controls.

Carriage Handwheel

The carriage handwheel moves the carriage left or right along the bed. It has a graduated dial with 0.01" increments, and one full revolution moves the carriage 0.80". Pull the handwheel out to disengage it during power feed operations— this will prevent entanglement hazards.

Cross Slide Handwheel

The cross slide handwheel moves the tool toward and away from the work. Adjust the position of the graduated scale by holding the handwheel with one hand and turning the dial with the other. The cross slide handwheel has a direct read graduated dial which means that the distance on the dial reflects the amount removed from the diameter of the workpiece. The dial has 0.001" (0.02mm) increments, and one full revolution moves the slide 0.100" (5.08mm). Rotate the dial collar 180° to read in metric units.

Compound Rest Handwheel

The compound rest handwheel moves the cutting tool linearly along the set angle of the compound rest. The compound rest angle is set by hand rotating it and securing in place with two hex nuts. The compound rest has an indirect-read graduated dial with 0.001" (0.02mm) increments. One full revolution of the handwheel moves the slide 0.100" (2.54mm). Rotate the dial collar 180° to read in metric units.

= SpindleSpeed (RPM) Figure 65. Spindle speed formula for lathes.

Cutting speed, typically defined in feet per minute (FPM), is the speed at which the edge of a tool moves across the material surface.

A recommended cutting speed is an ideal speed for cutting a type of material in order to produce the desired finish and optimize tool life.

The books Machinery’s Handbook or Machine

Shop Practice, and some internet sites, provide

excellent recommendations for which cutting speeds to use when calculating the spindle speed. These sources also provide a wealth of additional information about the variables that affect cutting speed and they are a good educational resource.

Also, there are a large number of easy-to-use spindle speed calculators that can be found on the internet. These sources will help you take into account the applicable variables in order to determine the best spindle speed for the operation.

Setting Spindle Speed

Selecting one of the 8 spindle speeds available is a combination of configuring the spindle range lever and the spindle speed lever shown in

Figure 66.

Speed Lever Spindle Range Lever


Configuration Examples

Using the controls on the lathe, follow along with these two examples for setting the spindle speed to gain a better understanding of this task.

Setting Spindle Speed of 200 RPM

1.

Make sure the spindle is completely stopped and the spindle lever is in the OFF (middle) position.

2.

Move the spindle range lever to the right so that the arrow on top of its hub points toward the

L

Power Feed

Both the carriage and cross slide have power feed capability when the carriage is engaged with the feed rod. The rate that these components move (feed rate) is controlled by the headstock and quick-change gearbox lever positions, and the end gear configuration.

Feed rate and spindle speed must be considered together. Keep in mind that the feed rate is expressed in the amount of travel per revolution of the spindle. The sources you use to determine the optimum spindle speed for an operation will also provide the optimal feed rate to use with that spindle speed.

Often, the experienced machinist will use the feeds and speeds given in their reference charts or web calculators as a starting point, then make minor adjustments to the feed rate (and sometimes spindle speed) to achieve the best results.

The carriage can alternately be driven by the leadscrew for threading operations. However, this section only covers the use of the power feed option for the carriage and cross slide components for non-threading operations. To learn how to power the carriage for threading operations, refer to Threading on Page 56.

Operating the lathe at spindle speeds higher than 350 RPM when the high (H) gearbox range is selected could result in gearbox damage. Always use spindle speeds of 350 RPM or lower when using the high (H) gearbox range.

Note:

When using this lever, you may need to slightly rotate the handwheel of the component you are trying to engage, so that the apron gears can mesh.

F. Apron Feed Direction Knob:

Changes the feed direction when the lathe is running.

The advantage of this knob is that you can quickly reverse power feed direction while the spindle is rotating—without having to turn the lathe off, waiting until the spindle is stopped, then using the feed direction lever on the headstock.

Depending on the combined configuration of the headstock feed direction lever and the apron feed direction knob, the actual direction of power feed may be different from the printed indicators on the machine!

Apron Threading Controls

The half nut lever engages the carriage with the leadscrew which moves the carriage and cutting tool, along the length of the workpiece for threading operations (see Figure 77).

Important:

Make sure the feed selection lever is in the disengaged (middle) position before attempting to engage the half nut.

Thread Dial

The numbers on the thread dial are used with the thread dial chart to show when to engage the half nut during inch threading. The thread dial gear must be engaged with the leadscrew for this to work. Loosen the knurled knob on the thread dial, pivot the dial gear toward the leadscrew so that it properly meshes with the leadscrew threads, then re-tighten the knob, as shown

Figure 78.

Leadscrew Dial Gear Feed Control Lever Half Nut Lever Disengaged Disengaged Carriage Feed Control Lever Engaged Figure 77. Apron threading controls.

Knurled Knob Figure 78. Thread dial engaged with the leadscrew.

When threading, we recommend using the slowest speed possible and avoiding deep cuts, so you are able to disengage the half nut when required and prevent an apron crash!

-57-




Thread Dial Chart

Find the TPI (threads per inch) that you want to cut in the left column of the thread dial chart (see Figure 79), then reference the dial number to the right of it. The dial numbers indicate when to engage the half nut for a specific thread pitch. The thread dial chart can also be found on the front of the thread dial housing.

Even TPI Not Divisible By 4

For threading a TPI that is even but not divisible by 4, use any of the non-numbered lines on the thread dial (see Figure 81).

Cleaning & Protecting

Regular cleaning is one of the most important steps in taking care of this lathe. We recommend that the cleaning routine be planned into the workflow schedule, so that adequate time is set aside to do the job right.

Typically, the easiest way to clean swarf from the bed ways and chip drawer is to use a wet/dry shop vacuum that is dedicated for this purpose. The small chips left over after vacuuming can be wiped up with a slightly oiled rag. Avoid using compressed air to blow off chips, as it may drive them deeper into moving surfaces and could cause sharp chips to fly into your face or hands.

Besides the ways, all other unpainted and machined surfaces should be wiped down daily to keep them rust-free and in top condition. This includes any surface that is vulnerable to rust if left unprotected (especially any parts that are exposed to water-soluble coolant). Typically, a thin film of oil is all that is necessary for protection.

M A I N T E N A N C E The following recommended lubrication schedules are based on light-to-medium usage. Keeping in mind that lubrication helps to protect the value and operation of the lathe, these lubrication tasks may need to be performed more frequently than recommended here, depending on usage.

Failure to follow reasonable lubrication practices as instructed in this manual could lead to premature failure of lathe components and will void the warranty.

Draining Oil & Flushing Reservoir

Since the apron oil reservoir supplies the one shot oiler, the oil is constantly being refreshed when the reservoir is filled. However, small metal particles may accumulate at the bottom of the reservoir with normal use. Therefore, to keep the reservoir clean, drain and flush it at least once a year.

Flush the reservoir by pouring a small amount of clean oil into the fill hole and allowing it to drain out the bottom.

Replace the drain plug and add oil as previously described.

One-Shot Oiler

The one-shot oiler shown in Figure 105 lubricates the saddle ways with oil from the apron reservoir.

Before lubricating the leadscrew, clean it first with mineral spirits. A stiff brush works well to help clean out the threads. Make sure to move the carriage out of the way, so you can clean the entire length of the leadscrew.

Apply a thin coat of oil along the length of the leadscrew. Use a stiff brush to make sure the oil is applied evenly and down into the threads.

To use the one-shot oiler, pull the pump knob out for two or three seconds and then push it in. The pump draws oil from the apron reservoir and then forces it through drilled passages to the way guides.

Repeat this process while moving the carriage and cross slide through their full range of movement to distribute oil along the ways.

Note:

In some environments, abrasive material can become caught in the leadscrew lubricant and drawn into the half nut. In this case, lubricate the leadscrew with a quality dry lubricant.

Lubricate the ways before and after operating the lathe. If the lathe is in a moist or dirty environment, increase the lubrication interval.

Check the apron oil level through the sight glass before using the one-shot oiler.

Cross Slide Leadscrew & Nut Compound Rest Leadscrew & Nut Feed Selection Lever Gearing Cross Slide Leadscrew Bearing This lathe has seven ball oilers and one oil cup that should be oiled on a daily basis before beginning operation.

Proper lubrication of ball oilers is done with a pump-type oil can that has a plastic or rubberized cone tip. We do not recommend using metal needle or lance tips, as they can push the ball too far into the oiler, break the spring seat, and lodge the ball in the oil galley.

E F

Lubricate the ball oilers before and after machine use, and more frequently under heavy use. When lubricating ball oilers, first clean the outside surface to remove any dust or grime. Push the rubber or plastic tip of the oil can nozzle against the ball oiler to create a hydraulic seal, then pump the oil can once or twice. If you see sludge and contaminants coming out of the lubrication area, keep pumping the oil can until the oil runs clear. When finished, wipe away any excess oil.

End Gears

Grease Type ............................................... NLGI#2 Frequency ................ Annually or When Changing The end gears, shown in Figure 109, should always have a thin coat of heavy grease to minimize corrosion, noise, and wear. Wipe away excess grease that could be thrown onto the V-belts and reduce optimal power transmission from the motor.

Figure 109. End gears.

Handling & Care

Make sure to clean and lubricate any gears you install or change. Be very careful during handling and storage—the grease coating on the gears will easily pickup dirt or debris, which can then spread to the other gears and increase the rate of wear.

Make sure the end gear cover remains installed whenever possible to keep the gears free of dust or debris from the outside environment.

Lubricating 1.


2.

Remove the end gear cover and all the end gears shown in

Figure 109.

3.

Clean the end gears thoroughly with mineral spirits to remove the old grease. Use a small brush if necessary to clean between the teeth.

4.

Clean the shafts, and wipe away any grease splatters in the vicinity and on the inside of the end gear cover.

5.

Using a clean brush, apply a thin layer of grease on the gears. Make sure to get grease between the gear teeth, but do not fill the teeth valleys.

6.

Install the end gears and mesh them together with an approximate 0.002" backlash. Once the gears are meshed together, apply a small dab of grease between them where they mesh together— this grease will be distributed when the gears rotate and re-coat any areas scraped off during installation.

7.

Re-install the end gear cover before re connecting the lathe to power.

Coolant System Service

The coolant system consists of a fluid tank, pump, and flexible nozzle. The pump pulls fluid from the tank and sends it to the valve, which controls the flow of coolant to the nozzle. As the fluid leaves the work area, it drains back into the tank through the chip drawer and catch tray where the swarf is screened out.

Use Figures 110–111 to identify the locations of the coolant system controls and components.

Coolant Pump Switch Nozzle & Valve Lever Figure 110. Coolant controls.


13" Heavy 13 ® Gearhead Lathe Although most swarf from machining operations is screened out of the coolant before it returns to the tank, small particles will accumulate in the bottom of the tank in the form of sludge. To prevent this sludge from being pulled into the pump and damaging it, the pump’s suction tube is positioned a couple inches from the bottom of the tank and fitted with a fine screen. This works well when the tank is regularly cleaned; however, if too much sludge is allowed to accumulate before the tank is cleaned, the pump will inevitably begin sucking it up.

Hazards

As coolant ages and gets used, dangerous microbes can proliferate and create a biological hazard. The risk of exposure to this hazard can be greatly reduced by replacing the old fluid on a monthly basis, or as indicated by the fluid manufacturer.

The important thing to keep in mind when working with the coolant is to minimize exposure to your skin, eyes, and lungs by wearing the proper PPE (Personal Protective Equipment), such as splash-resistant safety goggles, long sleeve waterproof gloves, protective clothing, and a NIOSH approved respirator.

Machine Storage

To prevent the development of rust and corrosion, the lathe must be properly prepared if it will be stored for a long period of time. Doing this will ensure the lathe remains in good condition for later use.

To prepare the lathe for storage: 1.

Run the lathe and bring all gearboxes to operating temperature, then drain and refill them with clean oil.

2.

Pump out the old coolant, then add a few drops of way oil and blow out the lines with compressed air.

8.

Cover the lathe and place it in a dry area that is out of direct sunlight and away from hazardous fumes, paint, solvents, or gas. Fumes and sunlight can bleach or discolor paint and make the chuck guard cloudy.

9.

Every few months, rotate by hand all gear driven components a few times in several gear selections. This will keep the bearings, bushings, gears, and shafts well lubricated and protected from corrosion—especially during the winter months.

Slide the carriage, micrometer stop, tailstock, and steady rest down the lathe bed to make sure that way spotting is not beginning to occur.

Backlash Adjustment

Backlash is the amount of free play felt while changing rotation directions with the handwheel. This can be adjusted on the compound rest and cross slide leadscrews. Before beginning any adjustment, make sure that all associated components have been cleaned and lubricated.

Cross Slide Tools Needed: Qty

Hex Wrench 3mm .................................................1

Hex Wrench 5mm ................................................1

The cross slide backlash is adjusted by loosening all four cap screws shown in Figure 114, then tightening the center set screw. This will push down on a wedge and force the leadscrew nut apart, taking up lash between the nut and leadscrew.

Reducing backlash to less than 0.002" is impractical and can lead to accelerated wear of the wedge, nut, and leadscrew. Avoid the temptation to overtighten the backlash set screw while adjusting. Cap Screws

Compound Rest Tools Needed: Qty

Hex Wrench 3mm .................................................1

The compound rest backlash is adjusted by tightening the set screws shown in Figure 113. When these screws are adjusted against the leadscrew nut, they offset part of the nut to remove play between the nut and leadscrew.

Set Screw Figure 114. Cross slide backlash adjustment screws.

Set Screws Figure 113. Compound rest backlash adjustment set screws.

To adjust the backlash, rock the handwheel back and forth, and tighten the screws slowly until the backlash is approximately 0.002"–0.003", as indicated on the graduated dial.

If you end up adjusting the nut too tight, loosen the set screws, tap the compound rest a few times with a rubber or wooden mallet, and turn the handwheel slowly back and forth until it moves freely—then try again.

To adjust the backlash, remove the compound rest and loosen the four cap screws. Then, rock the cross slide handwheel back and forth, and tighten the set screw slowly until the backlash is at approximately 0.002"–0.003" as indicated on the graduated dial. If you end up adjusting the nut too tight, loosen the set screw, tap the cross slide a few times with a rubber or wooden mallet, and turn the handwheel slowly back and forth, until the handle turns freely—then try again.

Remember to re-tighten the four cap screws when you are finished.

End Nut & Set Screws

Gib Adjustment

The goal of adjusting the gib screws is to remove sloppiness or "play" from the ways without over adjusting them to the point where they become stiff and difficult to move.

In general, loose gibs cause poor finishes and tool chatter; however, over-tightened gibs cause premature wear and make it difficult to turn the handwheels.

Important:

Before adjusting the gibs, loosen the locks for the device so that the gibs can freely slide during adjustment, then lubricate the ways.

The gibs are tapered and held in position by a screw at each end. To adjust the gib, turn one screw 1 ⁄ 4 turn clockwise and the other screw the feel of the sliding component by turning necessary to make it tighter or looser.

1 the handwheel, and adjust the gib screws as ⁄ 4 turn counterclockwise, so both screws move in the same direction and the same amount. Test The gib adjustment process usually requires some trial-and-error. Repeat the adjustment process as necessary until you find the best balance between loose and stiff movement. Most machinists find that the ideal gib adjustment is one where a small amount of drag or resistance is present, yet the handwheels are still easy to move.

3.

Engage the half nut with the leadscrew.

Half Nut Adjustment

The clamping pressure of the half nut is fully adjustable with a gib that can be loosened or tightened by two set screws. Use this procedure to adjust the half nut if it becomes loose from wear, or it is too tight for your preferences. A half nut that is too loose will make it difficult to produce accurate work. A half nut that is too tight will increase the rate of wear on itself and the leadscrew.

Tool Needed: Qty

Hex Wrench 3mm .................................................1

To adjust the half nut: 1.

Disengage the half nut, then remove the thread dial.

2.

Turn the two set screws (see Figure 121) clockwise to tighten the half nut and counterclockwise to loosen it.

Note:

Make sure to turn the set screws in even amounts so that one end of the gib does not become tighter than the other.

V-Belts

V-belts stretch and wear with use, so check the tension on a monthly basis to ensure optimal power transmission. Replace all of the V-belts as a matched set if any of them show signs of glazing, fraying, or cracking.



Open End Wrench 24mm......................................1

To adjust the V-belts:

1.


2.

Remove the end gear cover and the motor access panel to expose the V-belts and pulleys (see Figure 122).

End Gear Cover Set Screws Figure 121. Half nut gib adjustment.

3.

Engage/disengage the half nut several times and notice how it feels. The half nut is correctly adjusted when it has a slight drag while opening and closing. The movement should not be too stiff or too sloppy.

4.

Repeat satisfied with the half nut pressure.

5.

Re-install the thread dial.

Brake & Switch

As the brake lining wears, the foot pedal develops more travel. If the brake band is not adjusted to compensate for normal wear, the limit switch will still turn the lathe off, but the spindle will not stop as quickly. It is especially important that the brake is kept properly adjusted so you can quickly stop the spindle in an emergency.



Hex Wrench 6mm .................................................1

To adjust the brake and brake switch: 1.


2.

Put on a respirator and eye protection to protect yourself from hazardous brake dust.

3.

Remove the motor access panel from the left cabinet.

4.

Measure the remaining brake band lining at the thinnest point, which is usually at the 8 o'clock position, as shown in Figure 124.

Figure 123. Adjusting V-belt tension.

4.

Firmly tighten the hex nuts to secure the setting, then re-install the covers.

3mm Figure 124. Minimum brake belt thickness.

When the brake band is new, the lining is approximately 6mm thick. If the lining thickness wears to 3mm or less, the brake band must be replaced. Otherwise, the rivets that secure the lining to the band will soon grind into the brake hub. If the hub becomes damaged, it must be replaced.

Leadscrew Shear Pin Replacement

The leadscrew is secured to a connecting collar that is part of the headstock drivetrain with the use of a soft-metal shear pin. The shear pin is designed to break and disengage the power transfer to the leadscrew to help protect more expensive lathe components in the case of a carriage crash or the lathe is overloaded.

Contact South Bend to order a replacement shear pin (Part Number PSB10121234) or use the specifications in Figure 128 to fabricate your own.

To replace the shear pin:

1.


2.

Rotate the shroud washer on the leadscrew shown in Figure 129, so that the cutout lines up with the shear pin head.

S E R V I C E 6.

Use the magnet to remove the shear pin head, then rotate the lathe spindle to line up the inner and outer bores, as shown in

Figure 131. Next, use the magnet to remove

the other half of the broken shear pin when it becomes visible.

Shear Pin Inner Bore


Outer Bore Figure 131. Shear pin bores aligned.

7.

Insert the blow gun tip into the shear pin hole, blow out the hole with compressed air, then put a drop of oil in the hole.

8.

Insert the new shear pin into the bore, as shown in Figure 132.

Note:

If the pin does not freely slide into the bore, DO NOT use a hammer on the pin or you may permanently damage the shear mechanism and bore, which would make it nearly impossible to remove and install a new shear pin later.

Instead, take the time to carefully line up the two bores. You may need to file a slight chamfer on the end of the pin to make it easier to insert.

Figure 132. New shear pin installed in bore.

9.

With the pin completely seated in the bore and the head flush with the leadscrew shoulder, slide the shroud washer against the shoulder, then rotate the washer 180° to completely cover the head of the shear pin, as shown in Figure 133.

Gap Installation

1.

Use mineral spirits and a clean lint-free rag to clean the mating surfaces of the gap, bed, and ways. If necessary, stone the mating surfaces to remove scratches, dings, or burrs.

2.

Wipe a thin layer of light machine oil on the mating surfaces.

3.

Place the gap insert into the gap and use a dead-blow hammer to align the insert with the lathe bed.

4.

Back off the dowel pin jack nuts, and lightly tap the dowel pins back into their respective holes until they are seated. This process will further help align the gap insert and bed mating surfaces.

5.

Install all fasteners and lightly snug them in place.

6.

Mount a dial indicator with a magnetic base to the top of the saddle to indicate alignment.

7.

First test the peak of the two prisms of the gap insert that the saddle rides on, then test the flanks of the prisms.

8.

Tighten the gap bed cap screws in an alternating manner and tap the side of the gap insert into alignment.

9.

Inspect the gap alignment 24 hours later to make sure the gap is still aligned. If necessary, loosen the gap bed cap screws and repeat Steps 7–8 until the insert is properly aligned.
