You can be seriously injured or killed by getting clothing, jewelry, or long hair entangled with rotating cutter/spindle. You can be severely cut or have fingers amputated from contact with rotating cutters. You can be blinded or struck by broken cutting tools, metal chips, workpieces, or adjustment tools thrown from the rotating spindle with great force. To reduce your risk of serious injury when operating this machine, completely heed and understand the following:

SAFETY

For Machines Mfd. Since 11/22

Additional Milling Machine Safety

Make sure you understand the function and proper use of all controls before starting. This will help you avoid making mistakes that result in serious injury.

DO NOT wear loose clothing, gloves, or jewelry, and tie back long hair. Keep all guards in place and secure. Always allow spindle to stop on its own. DO NOT stop spindle using your hand or any other object.

Always wear a face shield in addition to safety glasses. This provides more complete protection for your face than safety glasses alone.

Follow recommended speeds and feeds for each size and type of cutting tool. This helps avoid tool breakage during operation and ensures best cutting results.

Clean Machine Safely: Metal chips or shavings

can be razor sharp. DO NOT clear chips by hand or compressed air that can force chips farther into machine—use a brush or vacuum instead. Never clear chips while spindle is turning.

Secure Workpiece To Table: Clamp workpiece

to table or secure in a vise mounted to table, so workpiece cannot unexpectedly shift or spin during operation. NEVER hold workpiece by hand during operation.

Properly Maintain Machine: Keep machine

in proper working condition to help ensure that it functions safely and all guards and

routine inspections and all necessary maintenance. Never operate machine with damaged or worn parts that can break or result in unexpected movement during operation.

Disconnect Power First: To reduce risk of

electrocution or injury from unexpected startup, make sure mill/drill is turned OFF, disconnected from power, and that all moving parts have come to a complete stop before changing cutting tools or starting any inspection, adjustment, or maintenance procedure.

Remove Chuck Key & Spindle Tools: Always

remove chuck key, drawbar wrench, and other tools used on the spindle immediately after use. This will prevent them from being thrown by the spindle upon startup.

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.

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.

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.)

Leveling machinery helps precision components, such as bed ways, remain straight and ﬂ at 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 ﬁ gure below for an example of a high precision level.

Generally, you can either bolt your machine to the ﬂ oor or mount it on machine mounts. Although not required, we recommend that you secure the machine to the ﬂ oor and level it while doing so. Because this is an optional step and ﬂ oor materials may vary, hardware for securing the machine to the ﬂ oor is not included.

PREPARATION

Leveling & Mounting

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.

Leveling

Anchoring to Floor

Number of Mounting Holes ..........................................4

Diameter of Mounting Hardware

Anchoring machine to the ﬂoor prevents tipping or shifting that may occur during operation with large/heavy workpieces.

If machine is installed in a commercial or workplace setting, or if it is permanently connected (hardwired) to the power supply, local codes may require that it be anchored to the ﬂoor.

Mounting to Concrete Floors

Lag shield anchors with lag screws (see below) are a popular way to anchor machinery to a concrete ﬂoor, because the anchors sit ﬂush with the ﬂoor surface, making it easy to unbolt and move the machine later, if needed. However, anytime local codes apply, you MUST follow the anchoring methodology speciﬁed by the code.

ScaleScale

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 mill 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 cutting tool, as noted in Figure 41:

*Recommended

Cutting Speed (FPM) x 12

Tool Dia. (in inches) x 3.14

Spindle

Speed (RPM)

*Double if using carbide cutting tool

Figure Figure 40. Ram rotating controls.. Ram rotating controls.

Note: In next step, take care not to entangle or

stretch electrical cabling as ram moves around turret.

Push on head to manually rotate it. Use

rotation scale to determine correct position for operation, then tighten (4) lock bolts to secure ram in place.

Figure Figure 41. Spindle speed formula for milling.. 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.

The "Recommended Cutting Speed" varies depending on the type of workpiece material. It is the ideal speed for cutting that material in order to optimize tool life and produce a desirable finish.

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

OPERATION

For Machines Mfd. Since 11/22

Setting Spindle Speed Range

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

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

• Spindle rotation must be turned OFF and spindle must be at a complete stop BEFORE you change spindle speed range.

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

• When changing spindle speed range, direction of spindle rotation will reverse due to change in gear configuration. You will need to use opposite spindle direction buttons when choosing spindle rotation direction.

Note: You MUST properly perform Meshing

Spindle & Spindle Clutch procedure as instructed on Page 37 when using high spindle speed range.

To set spindle speed range:

1. Make sure spindle rotation is turned OFF

and spindle is at a complete stop.

Use chart below to find spindle speed range

that includes required spindle speed for your operation.

Spindle Speed Ranges

Low Range 60–575 RPM

High Range 575–4200 RPM

3. Press spindle speed range lever shown in

Spindle Downfeed

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

For Machines Mfd. Since 11/22

D. Quill Lock Lever: Locks quill in vertical

position.

E. Downfeed Stop & Locking Wheel: Sets depth

of spindle downfeed. The stop is threaded into position, and locking wheel is used to secure it in place.

Downfeed Controls

Refer to Figure 44 and the descriptions below to become familiar with the downfeed components that control spindle downfeed travel.

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

Figure Figure 44. Fine downfeed controls.. Fine downfeed controls.

F. Downfeed Scale: Used with downfeed

stop and quill dog, shows depth of spindle downfeed in inches.

G. Fine/Auto Downfeed Clutch Lever: Engages

fine/auto-downfeed gears.

H. Auto-Downfeed Direction Pin: Starts, stops,

and reverses auto-downfeed direction.

I. Fine Downfeed Handwheel: Manually

controls fine spindle downfeed.

Setting Downfeed Stop

The downfeed stop (see Figure 44) sets the depth of spindle travel for repeat operations. The upper edge of the downfeed stop aligns with marks on the downfeed scale to help you set the approximate depth. However, the downfeed scale functions as a general guide only, and is not intended for low-tolerance, precision results.

To set the downfeed stop, rotate the stop until the upper edge aligns with the desired depth indicated on the scale, then tighten the locking wheel against the stop to secure it.

A. Auto-Downfeed Rate Selector: Selects one of

three auto-downfeed rates.

• 0.0015 in/rev

• 0.003 in/rev

• 0.006 in/rev

B. Downfeed Selector: Sets mill for manual

downfeed or auto-downfeed control.

C. Quill Dog: Moves with quill and spindle, and

disengages downfeed clutch lever when it meets either top or downfeed stop.

South Bend Tools

For Machines Mfd. Since 11/22 Model SB1124F

OPERATION

Using Coarse Downfeed

Coarse downfeed is typically used for drilling because it allows you to quickly lower the spindle with varying speed and pressure, and it automatically retracts the spindle to the top position when released.

To maintain control of upward spindle travel and the rotating bit in the workpiece, always continue holding the handle until the spindle returns to the top position. Letting go of the handle too soon will cause the spindle to retract too quickly and slam up into the headstock.

To use coarse downfeed:

1. DISCONNECT MACHINE FROM POWER!

2. Pull downfeed selector knob out, and rotate

it clockwise until selector pin under knob seats in forward manual (disengaged) position, as shown in Figure 45.

3. Make sure selector pin is firmly seated

in detent by attempting to move selector without pulling knob out.

Make sure pin in coarse downfeed handle

hub is engaged with one of the detents on downfeed sleeve (see Figure 46).

OPERATION

For Machines Mfd. Since 11/22

Using Fine Downfeed

Fine downfeed is used for precise Z-axis positioning of a cutter or end-mill when milling a flat surface across the face of a workpiece. In order to ensure the milled surface remains flat, the quill lock lever should be locked after each adjustment to ensure the spindle height cannot move until the entire milling operation is complete.

To use ﬁne downfeed:

1. DISCONNECT MACHINE FROM POWER!

2. Pull downfeed selector knob out, then rotate

selector clockwise until selector pin seats in forward manual (disengaged) position (see Figure 45).

Note: It may be necessary to turn spindle by

hand while moving selector to enable gears to mesh.

Using 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.

To use auto-downfeed system:

1. Make sure spindle rotation is turned OFF

and spindle is at a complete stop.

Pull downfeed selector knob out, rotate

selector clockwise, and seat pin in rear autodownfeed (engaged) position, as shown in Figure 47.

Set auto-downfeed direction pin (see Figure

44 on Page 38) in neutral (middle) position to disengage fine downfeed handwheel from auto-downfeed gears.

Position downfeed stop for spindle depth that

is correct for your operation, then secure it in place with locking wheel.

Use coarse downfeed lever to slightly lower

spindle until you can pull clutch lever out to left and it locks in place. This will engage fine handwheel with quill and spindle.

Rotate fine downfeed handwheel to raise

or lower spindle. When quill dog meets downfeed stop, clutch lever will disengage and spindle will return to top.

4. Position auto-downfeed direction pin for

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

OPERATION

To avoid risk of gear damage, always start spindle rotation BEFORE using auto-downfeed rate selector.

Note: 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 in and out positions is relative to direction of spindle rotation. Keep in mind that spindle rotation and downfeed direction will reverse when spindle speed range is changed.

Make sure clutch lever is all the way right in

disengaged position so spindle will not travel when rotation is started.

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

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

Select one of three downfeed rates (see

Figure 48) by pulling auto-downfeed rate selector knob out, positioning selector over appropriate detent, and releasing knob. Make sure pin is firmly seated by attempting to move selector without pulling knob out.

H = 0.006 in./rev. L = 0.0015 in./rev. M = 0.003 in./rev.

Maintenance

MAINTENANC E

Maintenance Schedule

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

For optimum performance from your machine, follow this maintenance schedule and refer to any specific instructions given in this section.

Ongoing

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

• Check/correct loose mounting bolts.

• Check/correct damaged or dull tools.

• Check/repair/replace worn or damaged wires.

• Clean/protect unpainted cast-iron surfaces.

• Clean dust or debris around machine.

• Resolve other unsafe conditions.

For Machines Mfd. Since 11/22

Daily After Operations

• Press EMERGENCY STOP button, turn master power switch to OFF position, and disconnect machine from power.

Vacuum/clean all chips and swarf from table,

• slides, and base.

Wipe down all unpainted or machined

• surfaces with a high-quality rust preventative.

Cleaning & Protecting

Regular cleaning is one of the most important steps in taking good care of this mill. 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.

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 this may drive them deeper into moving surfaces and could cause sharp chips to fly into your face or hands.

Daily Before Operations

• Turn master power switch to OFF position, and press EMERGENCY STOP button to prevent spindle startup when connected to power.

Move fine downfeed clutch lever to right

• (disengaged) position to prevent spindle from unexpectedly auto-downfeeding when spindle rotation begins.

Ensure X-axis power feed is turned OFF to

• prevent unintentional table movement when connected to power.

Check table movement in all three axis

• directions for loose/tight gibs. Adjust gibs as necessary (see Page 59).

Perform lubrication tasks as directed in

• Lubrication (see Page 50).

Check coolant reservoir in base. Fill it

• or clean it out as instructed in Coolant Reservoir (see Page 55).

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 any surface 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.

Keep tables rust-free with ISO 68 way oil.

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.

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 MACHINE 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.

Use the schedule and information in Figure 67 as a 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.

Coolant Reservoir

Hazards

As some coolant ages, it develops dangerous microbes which eventually proliferate and create a biological hazard. The risk of exposure to this hazard can be greatly reduced by cleaning out the coolant reservoir on a monthly basis or sooner, if needed based on your daily inspection.

The important thing to keep in mind when working with coolant is to minimize exposure to your skin, eyes, and respiratory system by wearing the proper personal protective equipment, which includes splash-resistant safety glasses, long-sleeve gloves, protective clothing, and a NIOSH-approved respirator.

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. However, be sure to follow the coolant manufacturer's instructions when checking, adding, or changing coolant.

The coolant reservoir holds approximately 20 liters of ﬂuid.

Running coolant pump without adequate coolant in reservoir may permanently damage coolant pump. This action is considered abusive and is not covered by warranty.

3. For a dip stick, use a clean, metal tool that

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 spindle to table:

1. DISCONNECT MACHINE FROM POWER!

2. Prepare mill by performing following tasks:

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

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

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

Place parallel block underneath spindle.

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: Generally, the goal in next steps is to

get difference of indicator readings between end of parallel block down to 0.0005". However, acceptable variance will depend on requirements for your operation.

Rotate spindle by hand so indicator point

rests on one end of parallel block, as illustrated in Figure 84, then zero dial.

Rotate spindle so indicator point rests in

same manner on other end of block, then read dial.

— If indicator dial still reads zero or is

within acceptable variance, proceed to Step 8.

— If indicator dial has moved from zero

beyond acceptable variance, you will need to compensate for that amount by rotating head left or right. Repeat Steps 6–7 until you are satisfied with spindle axis alignment along table X-axis.

Note: If you must re-position quill or knee to

accommodate above step, then review tasks in Step 2 to make sure mill is properly prepared for tramming operation.

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.

— If indicator dial still reads zero or is

within acceptable variance, spindle is precisely perpendicular to table in both X- and Y-axes, and tramming procedure is complete.

— If indicator dial has moved from zero

beyond acceptable variance, you will need to compensate for that amount by tilting head forward or back. Repeat Steps 10– 11 until you are satisfied with the spindle axis alignment along the table Y-axis.

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 MACHINE FROM POWER BEFORE ADJUSTING 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 86–88 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 gib adjustment screws.

Note: Keep one of the tilt lock bolts snug

so head does not move loosely while you adjust it in small amounts.
