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.

Lathe

Dating back to 1931, the first South Bend 8"

Bench Lathe made it much easier for machinists around the world to own a professional-duty lathe of exacting precision that was built to provide a lifetime of dependable service. In this same tradition, we are proud to offer the SB1001

8K Variable-Speed Bench Lathe.

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.

Now, almost 300 years later, these modern lathes are a refined culmination of human ingenuity and knowledge embodied into the design and synergy of many different 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 carry on the tradition. As the operator of a South Bend

Lathe, you join the ranks of some very famous and important customers, such as Henry Ford, who used his South Bend lathe to help him change the world.

This lathe is especially designed for discriminating machinists making small parts to extremely precise tolerances (jewelers, RC enthusiasts, watchmakers, model makers, optical engineers, gunsmiths, etc.).

Its compact size with heavy-duty construction and traditional South Bend “big lathe” features also make this lathe equally valuable for close-in precision toolroom or manufacturing operations.

The bed is constructed of hardened and ground castings in the traditional three V-way prismatic design—long used on South Bend Lathes for accuracy, durability, and rigidity. Its length allows for 18" between centers.

The headstock features a D1-3 variable-speed spindle that operates at 50–2300 RPM. Spindle speed changes are done very quickly and accurately with the convenient adjustment knob and digital display. Variable speed control allows the operator to “dial in” the perfect cutting speed for super-fine finishes.

The carriage has longitudinal power feeding capabilities with 9 available feed speeds ranging from 0.003"–0.0051" per revolution.

Thank you for being a part of the new South

Bend Lathe Co. We appreciate your business and hope this machine serves you well for a lifetime!

The South Bend 8K is capable of cutting inch or metric threads—12 inch threads from 10–32 TPI and 12 metric threads from 0.4–3.0mm.

Accessories include a heavy-duty tailstock, a

4-way tool post, MT#2 dead center, MT#3 dead center, and 3-jaw scroll chuck.

Additional Metal Lathe Safety

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.

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.

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.

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 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. A correct, sharp tool decreases strain and provides a better finish.

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.

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, 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.

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.

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.

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.

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

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.

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.

All chucks must be properly 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.

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. 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 procedures.

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.

Nominal Voltage ............................... 110V/120V

Cycle .............................................................60 Hz

Phase ..............................................Single-Phase

Circuit Rating....................................... 15 Amps

Plug/Receptacle ...............................NEMA 5-15

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.

Full-Load Rating .................................. 10 Amps

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.

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.

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.

Model SB1001 8K

™

Lathe

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.

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

Leveling & Mounting

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.

Leveling

Leveling machinery helps precision components, such as bed ways, remain straight and flat during the lifespan of the machine. Components on an unleveled machine 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.

Mounting

The base of this lathe has mounting four holes that allow it to be secured to a workbench or stand to prevent it from moving during operation. The mounting holes are 5

1. Puts on safety glasses, rolls up sleeves, removes jewelry, and secures any clothing, jewelry, or hair that could get entangled in moving parts.

Note:

Due to the generic nature of this overview, it is not intended to be an instructional guide for performing actual machine operations.

To learn more about specific operations and machining techniques, seek training from people experienced with this type of machine, and do additional research outside of this manual by reading "how-to" books, trade magazines, or websites.

2. Examines the workpiece to make sure it is suitable for turning, mounts the workpiece in the chuck, and removes the chuck key from the machine.

3. Mounts the tooling, aligns it with the workpiece, then backs it away to establish a safe startup clearance.

4. Removes all setup tools from the lathe.

To reduce the risk of serious injury when using this machine, read and understand this entire manual before beginning any operations.

5. Checks for safe clearances by rotating the workpiece by hand at least one full revolution.

6. Uses the master power switch to enable power to the motor, then rotates the spindle switch to the forward (left) position to start spindle rotation.

7. Rotates the spindle speed dial to select the correct spindle speed for the operation.

Loose hair, clothing, or jewelry could get caught in machinery and cause serious injury or death.

Keep these items away from moving parts at all times to reduce this risk.

8. Uses the handwheel/ball handles or power feed options to move the tooling into the workpiece.

9. When finished cutting, moves the spindle switch to the OFF (middle) position, waits until the spindle is completely stopped, then removes the workpiece.

Chuck & Faceplate

Mounting

This lathe is equipped with a D1-type spindle nose. This type of spindle uses camlocks that are adjusted with an 8mm hex wrench to securely mount a chuck or faceplate with repeatable precision and ease.

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!

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.

To install the chuck:

1. DISCONNECT LATHE FROM POWER!

2. Place a sturdy piece of plywood under the spindle to protect the bed ways during the installation process (see Figure 18).

This lathe is shipped with the 3-jaw chuck installed. This is a D1-3 scroll-type chuck where all three jaws move in unison when the chuck key is used.

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

If neither chuck can hold your workpiece, use a faceplate which 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 nonconcentric workpieces, straight turning between centers, off-center turning, and boring.

See Accessories on Page 46 for available 4-jaw chuck and faceplate options from South Bend.

Plywood Protection for the Bed Ways

4. Align the registration mark on the chuck

(see Figure 19) with the one on the spindle.

Note: The camlock studs were adjusted at the factory to correctly fit the corresponding spindle cam hole, then the registration marks were made so that the chuck can be mounted with the same alignment each time.

Marks

Figure 19. Chuck and spindle registration marks.

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

Important: Avoid inserting the studs at an angle—this can damage studs or spindle cam holes.

CORRECT INCORRECT

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

7. When the chuck is fully seated and all the camlocks are tight, 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, reclean 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 on the next page, 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, reclean the mating surfaces carefully, and re-install. If the problem persists, contact our Tech Support.

Chuck Removal

To remove the chuck:


2. Place a sturdy piece of plywood under the spindle to protect the bed ways during the removal process.

3. Loosen the camlocks by turning the key counterclockwise until each of the cam lines are aligned with its corresponding spindle mark (see Figure 21).

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.

Faceplate

Refer to the Chuck Installation (Page 25) and Chuck Removal (Page 27) instructions to install or remove the faceplate.

The optional Model SB1469 cast-iron faceplate 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.

Only machine a non-concentric workpiece at low speeds and clamp counter-weights to the faceplate to balance it. Machining a nonconcentric workpiece at a high speed could cause it to be thrown from the spindle with deadly force at the operator or bystanders.

3. Position the workpiece onto the faceplate and clamp it in place with a minimum of three independent clamping devices (see

Figure 25 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.

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.

Live Centers

A live center (see Figure 35 for an example) has bearings that allow the center tip and the workpiece to rotate together—it can be installed in 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.

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

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

When the dead center is used in the tailstock, the workpiece pivots on the tip of the center. The tip 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.

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). 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.

To mount a center in the tailstock:


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: This helps ensure that the tool seats properly and has minimal runout.

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. 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 the center may become difficult to remove later, and the excess pressure will result in unnecessary friction and heat, which may damage the workpiece and center.

Tip: If setting up to cut external right-hand inch or metric threads, or internal left-hand threads for the first time, set the compound rest so its travel is perfectly parallel with the cross slide. Then, using a protractor, rotate the compound 29.5° counterclockwise and mark the new location on the cross slide.

This mark will be the quick reference point for setting the offset angle. To mark for internal right-hand threads or external lefthand threads, repeat this process, but rotate the rest 29.5° clockwise and mark the cross slide accordingly.

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 cap screws.

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 illustrated in

Figure 44.

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 31 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.

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 cut, as noted in the formula shown in Figure

46.

Figure 46. 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.

The position of the feed direction gears controls the rotation of the longitudinal leadscrew as follows:

• Standard: Leadscrew rotates in the same direction as the spindle.

• Reverse: Leadscrew rotates in the opposite direction as the spindle.

• Neutral: Leadscrew and end pulleys are disengaged from the drive train. This configuration can be used to save wear on the end pulleys and timing belts when tool position is manually controlled.

Maintenance Schedule

!

Always disconnect machine from power before performing maintenance or serious personal injury may result.

Daily, After Operations

• Turn the spindle switch to the OFF position, depress the STOP button, and shut OFF the master power switch (to prevent accidental startup).

• Vacuum/clean all chips and swarf from bed, slides, and benchtop or stand.

• Wipe down all unpainted or machined surfaces with an lightly-oiled rag.

Ongoing

To maintain a low risk of injury and proper machine operation, if you ever observe any of the items below, shut down the machine immediately and fix the problem before continuing operations.

• Loose mounting bolts or fasteners.

• Worn, frayed, cracked, or damaged wires.

• Emergency STOP button not working correctly or not requiring you to reset it before starting the machine again.

• Loose, worn, or damaged drive belts or timing belts.

• Damaged or malfunctioning components.

Annually

• Check/level bedway (Page 19).

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 bedways 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 lightly-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.

Daily, Before Operations

• Lubricate the spindle bearings (Page 49).

• Lubricate feed direction gears (Page 50).

• Lubricate grease fittings (Page 51).

• Clean/lubricate the longitudinal leadscrew

(Page 51).

• Lubricate 3-jaw chuck (Page 52).

• Clean/lubricate the bedways and slides

(Page 52).

• Check condition and tension of drive belts

(Page 55) and timing belts.

• Check for loose or damaged timing-belt pulleys.

• Turn the spindle speed dial all the way counterclockwise (to prevent high-speed startup).

• Disengage the half nut lever on the apron (to prevent crashes upon startup).

• Ensure the carriage lock is loose.

In addition to 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 (especially any parts exposed to water soluble cutting fluid). Typically, a thin film of good quality way oil is all that is necessary for protection. (Refer to Accessories on Page 46 for an option from South Bend.)

The timing belts and pulleys should remain free from grease and grime. Clean the pulleys with mineral spirits when changing configurations, then allow them to dry. Wipe the timing belts with a clean, dry shop rag at the same time.

Lubrication

The lathe has numerous metal-to-metal sliding surfaces that require regular lubrication to maintain smooth movement and ensure longlasting operation.

Spindle Bearings

Oil Type .. Mobil DTE Light or ISO 32 Equivalent

Lubricating Device ................ Pump-Type Oil Gun

Amount ................................................. 1–2 Pumps

Frequency .......................................................Daily

Other than the lubrication points covered in this section, all other bearings are internally lubricated and sealed at the factory. Simply leave them alone unless they need to be replaced.

The spindle bearing lubrication fittings are located on either side of the headstock (see

Figure 80).

Before performing any lubrication task,

DISCONNECT LATHE FROM POWER!

Important: Before adding lubricant, clean away any debris or grime from the entry points with mineral spirits to prevent contamination of the new lubricant.

Oil Gun

Proper lubrication of the spindle bearing and chuck fittings is done with a pump-type oil gun 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 fitting, break the spring seat, and lodge the ball into the oil galley. Push the rubber or plastic tip of the oil can nozzle against the ball to create a hydraulic seal, then add the lubricant.

Use the schedule and information in the chart below as a daily guide for lubrication tasks.

Right Spindle

Bearing Fitting

Left Spindle

Bearing Fitting

Figure 80. Spindle bearing lubrication fittings.

Use only an ISO 32 equivalent oil to lubricate the spindle bearings. Using a heavier lubricant such as grease will cause the bearing to run hot and cause excessive machine wear.

The following schedule is based on light-tomedium usage. Some components may need to be lubricated more frequently depending on usage.

Machine Storage

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

To prepare the lathe for storage:


2. Thoroughly clean all surfaces, then apply a heavy coat of way oil to unpainted and bare metal surfaces.

Leadscrew End Play

Adjustment

After a long period of time, you may find that the leadscrew develops a small amount of end play. This end play can be removed with an adjustment of the lock collars on the right end of the leadscrew.

Tools Needed: Qty

Hex Wrench 2.5mm ..............................................1

To remove leadscrew end play:


3.

Lubricate the machine as outlined in

Lubrication, beginning on Page 51, then move/rotate the components through the full range of motion several times to distribute the lubricant.

4. 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 that could damage the surfaces of the lathe.

5.

Once or twice a month, move the carriage, tailstock, and other components mounted on the bedway down the bed to make sure that rust is not beginning to occur. If it is, remove it and re-apply a heavy coat of way oil.

6.

Every few months, repeat Step 3.

2. Insert the hex wrench or similar tool into a hole on the rim of the outside leadscrew lock collar (see Figure 88) to loosen it a couple of turns.

Gib Adjustment

The goal of adjusting the gib screws is to remove sloppiness or "play" from the ways without overadjusting 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.

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.

Before you begin adjusting the gibs, make sure the ways are free of chips and grime, and they are well lubricated so they can move smoothly and without interference.

Saddle Gib

The saddle gib is located underneath the rear of the saddle (see Figure 89). This gib is a flat bar that is sandwiched between the gib plate and the bedway.


Wrench 8mm .........................................................1

Hex Wrench 2.5mm ..............................................1

To adjust the saddle gib:


2. Make sure the carriage lock is loose and the half nut is disengaged so that the carriage can move freely.

3. Loosen the hex nuts on the gib screws, then loosen the gib screws two or three turns.

4.

Use the handwheel to move the carriage back and forth—this will ensure the gib is loose.

5.

Re-tighten the gibs screw evenly until a slight resistance is felt, then use the handwheel to test carriage movement.

— Loosen or tighten the gib screws evenly until you are satisfied with the gib adjustment.

6. Without moving the gib screws, re-tighten the hex nuts to secure the settings.

Cross Slide & Compound Rest

Gibs

The gibs for the cross slide and compound rest are flat bars that are held between the component and the dovetail way by the gib screws (see Figures 90–91).

Adjust these gib screws in the same manner as the carriage gib screws.
