About This Machine

Foreword

"Most boys should learn a trade in order that they may become skilled workmen. The trained workman is always in demand...When a boy has learned a trade, becomes a skilled mechanic, he has excellent equipment with which to begin life's battle, but he need not stop there. George

Westinghouse, the Wright Brothers, Henry Ford, and the Studebaker Brothers were mechanics, and it was their mechanical training that

made their success possible." —Machine Shop

Equipment, 2nd Ed., 1920, by the O'Brien

Brothers, founders of South Bend Lathe.

Capabilities

This Milling Machine is built for daily, non-stop use in a busy industrial setting, tool room, or school shop. It is easy to set-up, truly accurate, and built to give you long years of service when properly cared for. This milling machine supports workpieces up to 750 lbs. and is perfect for face milling, end milling, planing, slot or keyway cutting, dovetailing, routing, drilling, reaming, and boring to name a few. With the movable ram and tilting head, all these tasks can be performed on horizontal, vertical, and angled surfaces.

When equipped with additional accessories, such as a rotary table or dividing head, this milling machine can do even more.

The first South Bend milling machine debuted in the 1950's. During that time, the milling machine and the already well-established South Bend lathes created the foundation of many tool rooms and school shops across America and beyond her borders. Many young people in those days came of age on South Bend equipment, becoming world-class machinists, mechanical engineers, inventors, and manufacturing visionaries.

Features

This milling machine features 3-axis table movement with built-in longitudinal power feed.

It is constructed with high-grade Meehanite castings, and the saddle and knee ways are

Turcite coated and built with wide dovetails for maximum support and accuracy through the full range of movement.

A lot has changed in the world since then. Those same school shops have mostly been replaced by computer labs. The technology in the rotary dial phone, television set, mechanical calculator, computer, and camera of that decade could barely fit into one large room together—now they fit into a tiny box that is no bigger than a box of breath mints. And the average production machinist spends more time at a computer than at a machine. Technology has been much refined and the world operates on a much faster pace.

But some things haven't changed. The same human ingenuity and passion that created the best mechanical technology of today still exists within us. The core machines of the modern shop, like this South Bend milling machine, are still fundamentally important.

To ensure quality work results, we have equipped this mill with NSK or NTN spindle bearings that are rated to P4 (ABEC-7) tolerances. The spindle taper is R8 and the spindle has powered down feed with fine, medium, and coarse feed controls.

The headstock is mounted on a wide-dovetail movable ram with 13" of travel on the column and 360° rotating capability. The headstock itself can swivel 90° left/right or 45° forward/back so it can be positioned for nearly any setup needed.

To reduce the time spent doing daily lubrication, we have outfitted this milling machine with a one-shot lubrication system that is as quick and easy as one pump of a lever.

When you think about it, the greatest mechanical technology of the future will be what we create today. As the owner of a South Bend milling machine, you are now part of a great legacy.

What will you create with yours?

Quality Allen-Bradley electrical components and attention to detail provide dependable electrical control of the powered movements.

And finally, this milling machine comes with a circulating coolant system with the pump and reservoir in the column base.

Understanding Risks of Machinery

Operating all machinery and machining equipment can be dangerous or relatively safe depending on how it is installed and maintained, and the operator's experience, common sense, risk awareness, working conditions, and use of personal protective equipment (safety glasses, respirators, etc.).

The owner of this machinery or equipment is ultimately responsible for its safe use. This responsibility includes proper installation in a safe environment, personnel training and usage authorization, regular inspection and maintenance, manual availability and comprehension, application of safety devices, integrity of cutting tools or accessories, and the usage of approved personal protective equipment by all operators and bystanders.

The manufacturer of this machinery or equipment will not be held liable for injury or property damage from negligence, improper training, machine modifications, or misuse. Failure to read, understand, and follow the manual and safety labels may result in serious personal injury, including amputation, broken bones, electrocution, or death.

The signals used in this manual to identify hazard levels are defined as follows:

Death or catastrophic harm WILL occur.

Death or catastrophic harm COULD occur.

Moderate injury or fire

MAY occur.

Machine or property damage may occur.

Basic Machine Safety

1. Owner’s Manual: All machinery and machining equipment presents serious injury hazards to untrained users. To reduce the risk of injury, anyone who uses

THIS item MUST read and understand this entire manual before starting.

2. Personal Protective Equipment: Operating or servicing this item may expose the user to flying debris, dust, smoke, dangerous chemicals, or loud noises. These hazards can result in eye injury, blindness, longterm respiratory damage, poisoning, cancer, reproductive harm or hearing loss.

Reduce your risks from these hazards by wearing approved eye protection, respirator, gloves, or hearing protection.

3. Trained/Supervised Operators Only:

Untrained users can seriously injure themselves or bystanders. Only allow trained and properly supervised personnel to operate this item. Make sure safe operation instructions are clearly understood. If electrically powered, use padlocks and master switches, and remove start switch keys to prevent unauthorized use or accidental starting.

4. Guards/Covers: Accidental contact with moving parts during operation may cause severe entanglement, impact, cutting, or crushing injuries. Reduce this risk by keeping any included guards/covers/doors installed, fully functional, and positioned for maximum protection.

-9-

Model SB1027 S A F E T Y For Machines Mfg. Since 8/09

5. Entanglement: Loose clothing, gloves, neckties, jewelry or long hair may get caught in moving parts, causing entanglement, amputation, crushing, or strangulation. Reduce this risk by removing/securing these items so they cannot contact moving parts.

11. Chuck Keys or Adjusting Tools: Tools used to adjust spindles, chucks, or any moving/ rotating parts will become dangerous projectiles if left in place when the machine is started. Reduce this risk by developing the habit of always removing these tools immediately after using them.

6. Mental Alertness: Operating this item with reduced mental alertness increases the risk of accidental injury. Do not let a temporary influence or distraction lead to a permanent disability! Never operate when under the influence of drugs/alcohol, when tired, or otherwise distracted.

12. Work Area: Clutter and dark shadows increase the risks of accidental injury.

Only operate this item in a clean, nonglaring, and well-lighted work area.

7. Safe Environment: Operating electrically powered equipment in a wet environment may result in electrocution; operating near highly flammable materials may result in a fire or explosion. Only operate this item in a dry location that is free from flammable materials.

13. Properly Functioning Equipment: Poorly maintained, damaged, or malfunctioning equipment has higher risks of causing serious personal injury compared to those that are properly maintained.

To reduce this risk, always maintain this item to the highest standards and promptly repair/service a damaged or malfunctioning component. Always follow the maintenance instructions included in this documentation.

8. Electrical Connection: With electically powered equipment, improper connections to the power source may result in electrocution or fire. Always adhere to all electrical requirements and applicable codes when connecting to the power source.

Have all work inspected by a qualified electrician to minimize risk.

9. Disconnect Power: Adjusting or servicing electrically powered equipment while it is connected to the power source greatly increases the risk of injury from accidental startup. Always disconnect power

BEFORE any service or adjustments, including changing blades or other tooling.

14. Unattended Operation: Electrically powered equipment that is left unattended while running cannot be controlled and is dangerous to bystanders. Always turn the power OFF before walking away.

15. Cancer or Respiratory Hazards: Certain cutting fluids and lubricants, or dust/ smoke created when cutting, may contain chemicals known to cause cancer, respiratory problems, birth defects, or other reproductive harm. Minimize exposure to these chemicals by wearing approved personal protective equipment and operating in a well ventilated area.

10. Secure Workpiece/Tooling: Loose workpieces, cutting tools, or rotating spindles can become dangerous projectiles if not secured or if they hit another object during operation. Reduce the risk of this hazard by verifying that all fastening devices are properly secured and items attached to spindles have enough clearance to safely rotate.

16. Difficult Operations: Attempting difficult operations with which you are unfamiliar increases the risk of injury.

If you experience difficulties performing the intended operation, STOP! Seek an alternative method to accomplish the same task, ask a qualified expert how the operation should be performed, or contact our Technical Support for assistance.

For Machines Mfg. Since 8/09 S A F E T Y Model SB1027

Additional Milling Machine Safety

1. Understanding Controls: The mill is a complex machine that presents severe cutting or amputation hazards if used incorrectly. Make sure you understand the use and operation of all controls before you begin milling.

6. Stopping Spindle: To reduce the risk of hand injuries or entanglement hazards, DO NOT attempt to stop the spindle with your hand or a tool. Allow the spindle to stop on its own or use the spindle brake.

2. Safety Accessories: Flying chips or debris from the cutting operation can cause eye injury or blindness.

Always use a chip guard in addition to your safety glasses or use a face shield when milling.

3. Work Holding: Milling a workpiece that is not properly clamped to the table could cause the workpiece to fly into the operator with deadly force! Before starting the machine, be certain the workpiece has been properly clamped to the table. NEVER hold the workpiece by hand during operation.

4. Spindle Speed: To avoid tool or workpiece breakage that could send flying debris at the operator and bystanders, use the correct spindle speed for the operation. Allow the mill to gain full speed before beginning the cut.

7. Chip Cleanup: Chips from the operation are sharp and hot and can cause burns or cuts.

Using compressed air to clear chips could cause them to fly into your eyes, and may drive them deep into the working parts of the machine. Use a brush or vacuum to clear away chips and debris from the machine or workpiece and NEVER clear chips while the spindle is turning.

8. Machine Care & Maintenance: Operating the mill with excessively worn or damaged machine parts increases the risk of machine or workpiece breakage, which could eject hazardous debris at the operator. Operating a mill in poor condition will also reduce the quality of the results. To reduce this risk, maintain the mill in proper working condition by ALWAYS promptly performing routine inspections and maintenance.

5. Spindle Direction Change: Changing spindle rotation direction while it is spinning could lead to impact injury from broken tool or workpiece debris, and workpiece or machine damage. ALWAYS make sure the spindle is at a complete stop before changing spindle direction.

9. Cutting Tool Usage: Cutting tools have very sharp leading edges—handle them with care!

Using cutting tools that are in good condition helps to ensure quality milling results and reduces the risk of personal injury from broken tool debris. Inspect cutting tools for sharpness, chips, or cracks before each use, and ALWAYS make sure the cutting tools are firmly held in place before starting the machine.

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, we have cleaned thousands of machines and found the following process to be the best balance between efficiency and minimized exposure to toxic fumes or chemicals.

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 area to make sure they will not damage it.

GAS

P R E P A R A T I O N

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.

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.

2. Place the lifting web straps under the ram and connect them to the safety hook, as illustrated in Figure 5.

Note: Place padding between the straps and the mill to protect the ram and ways, and to keep from cutting the lifting straps.

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.

Lifting

Web Straps

The method of lifting and moving the mill described below requires at least two other people for assistance, and a forklift with two lifting web straps rated for at least 3000 lbs. each.

Turret

Lock Bolts

Important: Before lifting the mill, make sure the four turret lock bolts (two on either side of the ram) are torqued to 47 ft/lbs.

Figure 5. Lifting the mill using web straps.

To lift and move the mill:

1. Swing the ram around 180° from the position that it was shipped in, then rotate the head upright, as illustrated in Figure 5

(refer to Ram Movement on Page 33 and

Headstock Movement on Page 29 for detailed instructions).

Note: After re-positioning the ram and headstock, make sure they are locked in place to prevent unexpected movement during lifting and moving.

3. Unbolt the mill from the shipping pallet.

4. With your assistants steadying the load to keep it from swaying, lift the mill a couple of inches.

— If the mill tips to one side, lower it to the ground and adjust the ram or table to balance the load. Make sure to re-tighten the lock levers and bolts before lifting the mill again.

— If the mill lifts evenly, continue to move it to its permanent location.

Bolting to Concrete Floors

Anchor

Bolt

We strongly recommend securing your machine to the floor if it is hardwired to the power source. Consult with your electrician to ensure compliance with local codes.

Lag Bolt and Anchor

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.

To level a machine, place metal shims under the contact points where the machine rests on the floor. 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.

Spindle Break-In


Complete the spindle bearing break-in procedure to avoid rapid deterioration of spindle components when the mill is placed into operation.


Since the mill head was rotated parallel to the table for shipping purposes, you will need to tram the spindle with the table if your first cut requires a 90° alignment. Refer to the

Tramming Spindle section on Page 30 for detailed instructions.

The high-quality bearings and gears used in the mill are manufactured to very close tolerances.

However, this does not guarantee perfect dimensional mating of the bearing components or exact meshing of gear teeth. Before operational stress is placed on these and other moving parts in the mill, complete this break-in procedure to conform these components to one another and ensure trouble-free performance from the mill.

To perform the spindle break-in procedure:

1. Successfully perform all the steps in the

Test Run section beginning on Page 21.

2. Make sure the spindle is at a complete stop.

3. Set the spindle speed to the low range (refer to Setting Spindle Speed beginning on

Page 34 for detailed instructions).

Tramming Spindle

After positioning the head at an angle and when your operation requires that the spindle axis be precisely perpendicular to the table, you must tram or align the spindle with the table to ensure the spindle is exactly 90° to the table.

This procedure involves mounting a dial test indicator to the quill or spindle, rotating it around the table, and adjusting the spindle axis (Z-axis) 90° to the table X- and Y-axes, as illustrated in Figure 27.

We encourage you to research the many variations of spindle tramming to find the one that works best for you. If you do not already have a preference for performing this operation, use the following widely-used procedure for accurately tramming the spindle to the table.

Keep in mind that all workpiece top surfaces are not exactly parallel with the table top. You may choose to tram the spindle to the top surface of the workpiece after it is mounted instead of that of the table.

Note: A precision-ground plate can be substituted for the parallel blocks. Keep in mind that the farther the indicator point can be placed from the spindle axis, the more accurate the alignment measurements will be.

To tram the spindle to the table:


2. Prepare the mill by performing the following tasks:

• Stone the table to remove all nicks and burrs, then clean off all debris. Verify the table is clean by running your hand over the top of it.

• Position the table for the milling operation you intend to perform after the tramming—preferably centered to the saddle.

• Tighten any table, knee, quill, or ram locks that should be tight during the intended milling operation.

3. Place the parallel block underneath the spindle.

4. Install the indicator holder into the spindle or onto the quill, then mount the indicator onto it so that the point is as parallel to the block as possible (see the illustration in

Figure 28 for an example).

Table

Figure 28. Dial test indicator mounted.

5. To measure spindle alignment along the

X-axis, place the parallel block directly under the spindle and indicator across the length of the table, as illustrated in Figure 29.

Note: If you must re-position the quill or the knee to accommodate the above step, then review the tasks in Step 2 to make sure the mill is properly prepared for the tramming operation.

Note: Generally, the goal in the next steps is to get the difference of the indicator readings between the end of the parallel bar down to

0.0005". However, the acceptable variance will depend on the requirements for your operation.

6. Rotate the spindle by hand so that the indicator point rests on one end of the parallel block, as illustrated in Figure 29, then zero the dial.

7. Rotate the spindle so that the indicator point rests in the same manner on the other end of the block, then read the dial.

— If the indicator dial still reads zero or is within the acceptable variance, continue on with Step 8.

— If the indicator dial has moved from zero beyond the acceptable variance, you will need to compensate for that amount by rotating the head left or right. Repeat

Steps 5–6 until you are satisfied with the spindle axis alignment along the table

X-axis.

9. Place the parallel block directly under the spindle and across the width of the table, as illustrated in Figure 30.

Note: Keep one of the rotation lock bolts snug so that the head does not move loosely while you adjust it small amounts.

8. Re-tighten the rotation lock bolts.

Note: It is a good idea to repeat Steps 5-6 again in case the head moved slightly during the process of re-tightening the lock bolts.

11. Rotate the spindle so that the indicator point rests on the other end of the bar in the same manner, then read the dial.

— If the indicator dial still reads zero or is within the acceptable variance, the spindle is precisely perpendicular to the table in both the X- and Y-axes and the tramming procedure is complete.

— If the indicator dial has moved from zero beyond the acceptable variance, you will need to compensate for that amount by tilting the head forward or back. Repeat

Steps 9–10 until you are satisfied with the spindle axis alignment along the table

Y-axis.

Note: Keep one of the tilt lock bolts snug so that the head does not move loosely while you adjust it small amounts.

12. Re-tighten the tilt lock bolts.

Note: It is a good idea to repeat Steps 9-10 again in case the head moved slightly during the process of re-tightening the lock bolts.

Setting Spindle Speed

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

To avoid damage to the spindle, gears, or cutting tools:

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 mill controls to produce the required spindle speed.

• Spindle rotation must be turned OFF and the spindle must be at a complete stop

BEFORE you change the spindle speed range.

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 cutting tool, as noted in Figure 33:

• The mill is designed to ONLY operate with the spindle speed range selector in either the high or low position. To avoid damaging the moving parts inside the headstock, never start spindle rotation without the range selector detent pin firmly seated in either the high or low position.

*

Recommended

Cutting Speed (FPM) x 12

Tool Dia. (in inches) x 3.14

*

Double if using carbide cutting tool

= SpindleSpeed (RPM)

• When changing the spindle speed range and the direction of spindle rotation reverses, you will need to either change the cutting tool for the direction of spindle rotation or use the spindle direction switch to compensate for the change.

Figure 33. Spindle speed formula for milling.

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

Setting Spindle Speed Range

Setting the spindle speed range involves using a lever to engage/disengage the spindle spline with the bull gear.

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.

To set the spindle speed range:


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.

2. Use the chart below to find the spindle speed range that includes the required spindle speed for your operation.

Low Range

High Range

Spindle Speed Ranges

60–575 RPM

575–5000 RPM

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 all applicable variables to determine the best spindle speed for the operation.

When the spindle speed range is changed, the direction of spindle rotation will reverse.

ALWAYS know which way the spindle is rotating before beginning the cutting operation.

-34-


3. Press the spindle speed range lever shown in Figure 34 toward the head to release the detent pin from the detent plate, move selector so that the pin is over the other detent, then release the selector.

— When the lever is pointing to the rear and the front detent is engaged, the low speed range is selected. Conversely, when the lever is pointing toward the front and the rear detent is engaged, the high speed range is selected.

Note: It may be necessary to turn the spindle by hand as you move the range lever to enable the gears to mesh.

Downfeed Controls

Spindle downfeed movement on the mill is controlled by three mechanisms: 1) The coarse downfeed handle, 2) the fine downfeed handwheel, and 3) the auto-downfeed system.

B. Fine Downfeed Handwheel: Manually controls fine spindle downfeed.

When the spindle rotation is reversed, either by changing the spindle speed range or by using the spindle direction switch, the direction of spindle auto-downfeed will reverse.

C. Auto-Downfeed Direction Pin: Starts, stops, and reverses the auto-downfeed direction.

D. Fine Downfeed Clutch Lever: Engages the fine/auto-downfeed gears.

E. Downfeed Scale: Used with the quill dog, shows the depth of spindle downfeed in inches.

F. Quill Lock Lever: Secures the quill in place for increased stability during operations.

G. Downfeed Stop & Locking Wheel: Sets the depth of spindle downfeed. The stop is threaded into position, then the locking wheel is used to secure it in place.

H. Quill Dog: Moves with the quill and spindle and disengages the downfeed clutch lever when it meets either the top or downfeed stop.

I. Downfeed Selector: Sets the mill for manual downfeed or auto-downfeed control.

Using the Fine Downfeed

Handwheel

1. Make sure that the spindle rotation is turned

OFF and the spindle is at a complete stop.

2. To set the downfeed for manual control, pull the downfeed selector knob out, then rotate the selector clockwise until the selector pin seats in the forward manual (disengaged) position.

3. Set the auto-downfeed direction pin in the neutral (middle) position to disengage the fine downfeed handwheel from the autodownfeed gears.

4. Position the downfeed stop for the spindle depth that is correct for your operation, then secure it in place with the locking wheel.

5. Use the coarse downfeed lever to slightly lower the spindle until you can pull the clutch lever out to the left and it locks in place. This will engage the fine handwheel with the quill and spindle.

6. To lower the spindle, rotate the fine downfeed handwheel. When the quill dog meets the downfeed stop, the clutch lever will disengage and the spindle will return to the top.

-37-


Using the Auto-Downfeed System

When using the auto-downfeed system, the spindle will move in the direction you choose with the auto-downfeed direction pin. When the quill dog reaches the top or meets the downfeed stop, the downfeed clutch lever releases. Then, if the spindle was traveling upward, the movement simply stops. If the spindle was traveling downward, then the spindle moves back to the top at a rate controlled by the return spring on the left side of the head.

1. Make sure that the spindle rotation is turned

OFF and the spindle is at a complete stop.

4. Position the auto-downfeed direction pin for the spindle travel that is correct for your operation. It may be necessary to rock the fine downfeed handwheel back-and-forth to move the pin all the way in or out.

Note: The direction pin has three positions: 1)

In for one downfeed direction, 2) middle for neutral or no movement, and 3) out for the reverse direction. The direction of spindle travel for the in and out positions is relative to the direction of spindle rotation. Keep in mind that spindle rotation and downfeed direction will reverse when the spindle speed range is changed.

2. To set the mill for auto-downfeed, pull the downfeed selector knob out, then rotate the selector clockwise and seat the pin in the rear auto-downfeed (engaged) position, as illustrated in Figure 40.

5. Make sure the clutch lever is all the way to the right in the disengaged position so that the spindle will not travel when rotation is started.

Auto-Downfeed (Engaged) Position

Note: We recommend that you complete the remaining steps without a cutting tool installed, without a workpiece in place, and the table lower than the maximum spindle downfeed travel. This will enable you to test and confirm the settings before beginning the actual cutting operation.

To avoid damage to the system gearing, never use the auto-downfeed system with spindle speeds over 3000 RPM.

Figure 40. Downfeed selector in the auto-downfeed

(engaged) position.

3. Position the downfeed stop for the spindle depth that is correct for your operation, then secure it in place with the locking wheel.

6. Set the mill for the correct spindle speed, then begin spindle rotation.

Spindle Brake

When pressed backward, the spindle brake lever

(see Figure 42) activates a switch that turns the spindle motor OFF and engages drum-type brake pads to stop spindle rotation.

7. Select one of the three downfeed rates by pulling the auto-downfeed rate selector knob out, position the selector over the appropriate detent, then release the knob.

Make sure the pin is firmly seated by attempting to move the selector without pulling the knob out.

Note: Refer to the illustration in Figure 41 when selecting the downfeed rate.

Cleaning

Regular cleaning is one of the most important steps in taking good care of this machine. Each operator is responsible for cleaning the machine immediately after using it or at the end of the day. We recommend that the cleaning routine be planned into the workflow schedule, so that adequate time is set aside to do the job right.

Lubrication

The mill has numerous moving metal-tometal contacts that require regular and proper lubrication to ensure efficient and long-lasting operation, and to protect your investment.

Typically, the easiest way to clean swarf from the ways and table is to use a wet/dry shop vacuum that is dedicated for this purpose only. The small chips leftover 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.

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.

Before performing any lubrication task,

DISCONNECT THE MILL FROM POWER!

Important: Before adding lubricant, clean the debris and grime from the oil cup or grease fitting and the immediate area to prevent contamination of the oil cups, grease fittings, or new lubricant.

All visible swarf should be removed from the mill during cleaning. Remember, personal neatness gives you personality!

Unpainted & Machined Surfaces

Besides the ways and elevation leadscrew, all other unpainted and machined surfaces should be wiped down daily to keep them rust-free and in top condition. This includes surface you can find that could be vulnerable to rust if left unprotected (this especially includes any parts that may be exposed to water soluble cutting fluids). Typically with these parts, a thin film of oil is all that is necessary for protection.

Use the schedule and information in Figure 45 as a daily guide for lubrication tasks.

The following recommended lubrication schedule is based on light to medium mill usage. Keeping in mind that lubrication helps to protect the value and operation of the mill, you may need to perform the lubrication tasks more frequently depending on your usage.

Use the correct personal protection equipment when handling cutting fluid. Follow federal, state, and fluid manufacturer requirements for proper disposal.


To check the coolant level:


2. Clean away debris and grime from the coolant drain screens on the base of the mill

(see Figure 56), then insert a clean and dry piece of wire through one of the screens to check the level of the coolant.

A small amount of coolant is lost during normal operation. Check the coolant reservoir regularly and fill it if necessary. We recommend changing the coolant every three months or sooner if it develops an unpleasant odor.

The coolant reservoir holds approximately five gallons (19 liters) of fluid.

Note: When the catch pan is full, empty it into the 5 gallon bucket, then repeat the process.


4. Remove the coolant reservoir access panel from the rear of the column.

Figure 57. Location of coolant pump.

6. Use rags, scrapers, and cleaning solvent to thoroughly clean out the bottom of the reservoir and the base of the pump. Make sure that the interior is completely dry before adding new coolant.

Note: Use a cleaning solvent that is compatible with the type of coolant. For instance, if you are using a water-base coolant, then use a water-base cleaning solvent.

7. When the reservoir and pump are clean and dry, replace the pump, access panel, and the drain plug.

8. Clean away debris and grime from the coolant drain screens on the base of the mill

(see Figure 56 on the previous page), then pour the coolant through one of the screens to fill the reservoir.

Machine Storage

To avoid rust problems or corrosion damage, use the following information to protect your investment when storing the mill for any length of time.

• DISCONNECT MILL FROM POWER!

• Lubricate the mill as directed in the

Lubrication section beginning on Page 43.

• Clean out the coolant reservoir in the base of the mill as directed in the Changing

Coolant section on Page 49.

• Thoroughly clean all unpainted, bare metal surfaces, then coat them with a light weight grease or rust preventative. Take care to ensure these surfaces are completely covered but that the grease or rust preventative is kept off painted surfaces.

Note: If the machine will be out of service for only a short period of time, use way oil or a good grade of medium-weight machine oil

(not auto engine oil) in place of the grease or rust preventative.

• Loosen the belts to prevent them from stretching during storage. Post a reminder on the mill that the belts need to be reinstalled or tensioned before resuming operations.

• Place a few moisture absorbing desiccant packs inside the electrical and control panel boxes.

• Cover and place the machine 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 plastic parts.

• At least once a month, start the mill and run all gear-driven components for a few minutes. This will keep the bearings, bushings, gears, and shafts well lubricated and protected from corrosion, especially during the winter months.

Adjusting Gibs

Gibs are tapered lengths of metal between two dovetail sliding surfaces. Gibs control the gap between these surfaces and how they slide past one another. Correctly adjusting the gibs is critical to producing good milling results.

Tight gibs make table movement more accurate but stiff. Loose gibs make moving the table sloppy but easier to do. The goal of gib adjustment is to remove unnecessary sloppiness without causing the ways to bind.

Gibs are adjusted with a screw on each end of the gib, that move the tapered gib back-andforth to increase or decrease the friction pressure between the sliding surfaces. The process of properly adjusting the gibs requires trial-anderror and patience.

DISCONNECT MILL FROM POWER BEFORE

ADJUSTING THE GIBS!

Make sure all table and knee locks are loose.

Then, loosen one gib adjustment screw and tighten the other the same amount to move the gib. Use the handwheel/crank to move table/ knee until you feel a slight drag in that path of movement.

Refer to Figures 58–60 on the next page to identify the locations of the table, saddle, and knee gibs, and one of the two adjustment screws for each.

Note: It will be necessary to remove small parts, such as way wipers and covers, to access the gib adjustment screws.

Adjusting Leadscrew

Backlash

Leadscrew backlash is the amount the leadscrew rotates before the attached device begins to move.

Although the mill is equipped with doublebronzed longitudinal and cross leadscrew nuts to minimize backlash, leadscrews will always have a certain amount of backlash that will increase with normal wear.

Generally, 0.005"–0.010" leadscrew backlash is acceptable to ensure smooth movement and reduce the risk of premature thread wear.

However, if you find it necessary to adjust leadscrew backlash, perform the procedures listed below.

Electrical Safety Instructions

These pages are accurate at the time of printing. In the constant effort to improve, however, we may make changes to the electrical systems of future machines. Study this section carefully. If you see differences between your machine and what is shown in this section, call Technical Support at (360)

734-1540 for assistance BEFORE making any changes to the wiring on the machine.

1.

Shock Hazard:

Working on wiring that is connected to a power source is extremely dangerous. Touching electrified parts will result in personal injury including but not limited to severe burns, electrocution, or death. Disconnect the power from the machine before servicing electrical components!

2.

Wire Connections:

All connections must be tight to prevent wires from loosening during machine operation. Double-check all wires disconnected or connected during any wiring task to ensure tight connections.

3.

Modifications:

Using aftermarket parts or modifying the wiring beyond what is shown in the diagram may lead to unpredictable results, including serious injury or fire.

5.

6.

7.

Circuit Requirements:

You MUST follow the requirements at the beginning of this manual when connecting your machine to a power source.

Capacitors/Inverters:

Some capacitors and power inverters store an electrical charge for up to 10 minutes after being disconnected from the power source. To reduce the risk of being shocked, wait at least this long before working on capacitors.

Wire/Component Damage:

Damaged wires or components increase the risk of serious personal injury, fire, or machine damage. If you notice that any wires or components are damaged while performing a wiring task, replace those wires or components before completing the task.

4.

Motor Wiring:

The motor wiring shown in these diagrams is current at the time of printing, but it may not match your machine.

Always use the wiring diagram inside the motor junction box.
