Page 17

WEARING PROPER APPAREL. Do not wear clothing, apparel or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to reduce risk of slipping and losing control or accidentally contacting cutting tool or moving parts.

HAZARDOUS DUST. Dust created by machinery operations may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material. Always wear a NIOSH-approved respirator to reduce your risk.

HEARING PROTECTION. Always wear hearing protection when operating or observing loud machinery. Extended exposure to this noise without hearing protection can cause permanent hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on machinery can become dangerous projectiles upon startup. Never leave chuck keys, wrenches, or any other tools on machine. Always verify removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use this tool for its intended purpose—do not force it or an attachment to do a job for which it was not designed. Never make unapproved modifications—modifying tool or using it differently than intended may result in malfunction or mechanical failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing and balance at all times when operating machine. Do not overreach! Avoid awkward hand positions that make workpiece control difficult or increase the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and bystanders at a safe distance from the work area. Stop using machine if they become a distraction.

GUARDS & COVERS. Guards and covers reduce accidental contact with moving parts or flying debris. Make sure they are properly installed, undamaged, and working correctly BEFORE operating machine.

FORCING MACHINERY. Do not force machine. It will do the job safer and better at the rate for which it was designed.

NEVER STAND ON MACHINE. Serious injury may occur if machine is tipped or if the cutting tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or loss of control. Before starting, verify machine is stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the risk of accidental injury, turn machine OFF and ensure all moving parts completely stop before walking away. Never leave machine running while unattended.

MAINTAIN WITH CARE. Follow all maintenance instructions and lubrication schedules to keep machine in good working condition. A machine that is improperly maintained could malfunction, leading to serious personal injury or death.

DAMAGED PARTS. Regularly inspect machine for damaged, loose, or mis-adjusted parts—or any condition that could affect safe operation. Immediately repair/replace BEFORE operating machine. For your own safety, DO NOT operate machine with damaged parts!

MAINTAIN POWER CORDS. When disconnecting cord-connected machines from power, grab and pull the plug—NOT the cord. Pulling the cord may damage the wires inside. Do not handle cord/plug with wet hands. Avoid cord damage by keeping it away from heated surfaces, high traffic areas, harsh chemicals, and wet/damp locations.

EXPERIENCING DIFFICULTIES. If at any time you experience difficulties performing the intended operation, stop using the machine! Contact our Technical Support at (570) 546-9663.

Additional Safety for Milling Machines

risk of operator injury. If normal safety precautions are overlooked or ignored,

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.

SAFETY ACCESSORIES: Flying chips or debris from the cutting operation can cause eye injury or blindness. Always use safety glasses or a face shield when milling.

WORK HOLDING: Milling a workpiece that is not properly secured to the table or in a vise 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.

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 spindle to gain full speed before beginning the cut.

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.

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.

CHIP CLEANUP: Chips from the operation are sharp and hot, which 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 machine or workpiece and NEVER clear chips while spindle is turning.

MACHINE CARE & MAINTENANCE: Operating the mill with excessively worn or damaged machine parts increases risk of machine or workpiece breakage which could eject hazardous debris at the operator. To reduce this risk, maintain the mill in proper working condition by ALWAYS promptly performing routine inspections and maintenance.

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 risk of personal injury from broken tool debris. Inspect cutting tools for sharpness, chips, or cracks before each use, and ALWAYS make sure cutting tools are firmly held in place before starting the machine.

Like all machinery there is potential danger when operating this machine. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this machine with respect and caution to decrease the

serious personal injury may occur.

SECTION 2: POWER SUPPLY

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrican or qualified service personnel in accordance with all applicable codes and standards.

Electrocution, fire, or equipment damage may occur if machine is not correctly grounded and connected to the power

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.

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

For your own safety and protection of

Note: The circuit requirements listed in this manual apply to 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 that the circuit is properly sized for safe operation.

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power supply circuit used for this machine must be sized to safely handle the full-load current 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.)

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

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

Any extension cord used with this machine must contain a ground wire, match the required plug and receptacle, and meet the following requirements:

Grounding Instructions

This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current.

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

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

The power cord and plug specified under “Circuit Requirements for 220V” has an equipment-grounding wire and a grounding prong. The plug must only be inserted into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances (see figure below).

No adapter should be used with the required plug. If the plug does not fit the available receptacle, or the machine must

Site Considerations

Weight Load

Physical Environment

Place this machine near an existing power source.

Shadows, glare, or strobe effects that may distract

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

Space Allocation

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

See below for required space allocation.

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

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

Electrical Installation

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

Lighting

Lighting around the machine must be adequate enough that operations can be performed safely.

or impede the operator must be eliminated.

Lifting & Placing

HEAVY LIFT! Straining or crushing injury may occur from improperly lifting machine or some of its parts. To reduce this risk, get help from other people and use a forklift (or other lifting equipment) rated for weight of this machine.

Power lifting equipment rated for at least 50% more than the weight of the machine and at least two other people are required to lift and place the mill.

To lift and move the mill:

Note: After repositioning ram and headstock,

make sure they are locked in place to prevent unexpected movement while lifting.

Torque the four turret lock bolts (two on each

side of ram, as shown in Figure 10) to 47 ft/ lbs. This will help keep ram from unexpectedly moving from force of lifting straps.

Turret Locking Bolts

(2 of 4)

Remove crate from shipping pallet then,

while still on pallet, move machine to installation location.

Rotate ram 180° so headstock faces back-

wards (see Figure 9), then rotate head upright.

Refer to Head Tilt on Page 26 and Ram

Movement on Page 27 for detailed instructions to help with this step.

Figure 10. Locations of turret locking bolts.

Place lifting straps under ram and connect to

a safety hook, as illustrated in Figure 9.

Note: Place protective material between

straps and mill to protect ram and ways, and to prevent cutting lifting straps.

Unbolt mill from shipping pallet.

6. With other people steadying the load to keep

it from swaying, lift machine a couple of inches.

— If mill tips to one side, lower it to the pallet

and adjust ram or table to balance load. Make sure to retighten lock levers and bolts before lifting mill again.

— If mill lifts evenly, remove shipping pallet

and lower mill.

Anchoring machinery to the floor prevents tipping or shifting and reduces vibration that may occur during operation, resulting in a machine that runs slightly quieter and feels more solid.

If the machine will be 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.

If not required by any local codes, fastening the machine to the floor is an optional step. If you choose not to do this with your machine, we recommend placing it on machine mounts, as these provide an easy method for leveling and they have vibration-absorbing pads.

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.

Leveling

Leveling machinery helps precision components, such as dovetail 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 Figure 11 for an example of a high precision level available from Grizzly.

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 mill controls to match the closest 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 25:

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 are a good educational resource.

Tramming the Mill

When your operation requires that the spindle axis be precisely perpendicular to the table, you must tram the mill. Simply adjusting the headstock tilt to the 90° mark on the tilt scale will not be precise enough for highly accurate results.

This procedure involves mounting a dial indicator to the quill or spindle, rotating it around the table, and adjusting the head position so that the spindle axis is 90° to the table X-axis, as illustrated in

Figure 32.

Tools Needed Qty

Dial Indicator (with at least 0.0005" resolution) . 1 Indicator Holder (mounted on quill/spindle) Precision Parallel Block (1-2-3 Blocks)

Note: A precision-ground plate can be substituted for the parallel block. The farther the indicator point can be placed from the spindle axis, the more accurate the alignment measurements will be.

To tram the mill:

— 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 operation you

intend to perform after tramming—preferably centered with the saddle.

— Tighten any table locks that should be tight

during the intended milling operation.

Place the parallel block underneath spindle.

Dial Indicator

Note: Generally, the goal is to get the differ-

ence of the indicator readings between ends of the parallel bar down to 0.0005". However, the acceptable variance will depend on the requirements for your operation.

Rotate the spindle by hand so that the indi-

cator point rests on one end of the parallel block, as illustrated in Figure 34, then zero the dial.

Rotate the spindle so that the indicator point

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

Table

Figure 33. Dial indicator mounted.

Place the parallel block directly under the

spindle and the indicator across the length of the table, as illustrated in Figure 34.

Note: If you must reposition the quill to

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

Table (Top View)

— 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

⁄2 that amount by tilting the head left or right. Repeat Steps 6–7 until you are satisfied with the spindle axis alignment along table X-axis.

Tip: Keep one of the tilting hex nuts snug so

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

Retighten the tilting hex nuts.

To reduce risk of shock or

power before adjustments, maintenance, or service.

Schedule

Regular maintenance will help ensure proper care of the equipment. We strongly recommend that all operators make a habit of following the maintenance procedures found in this section. For optimum performance from this machine, this maintenance schedule must be strictly followed.

Ongoing

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

Before Beginning Operations

• Make sure the electric cabinet door is closed

and properly latched.

• Press the Emergency STOP button on the

master control panel to prevent high-speed spindle startup when connected to power.

• Make sure the X-axis power feed is turned

OFF to prevent unintentional table movement when connected to power.

• Check the coolant reservoir in the base. Fill it

or clean it out if necessary (see Page 46).

• Perform all required lubrication tasks (see

Page 41).

• Check table movement in all three axes for

loose/tight gibs. Adjust the gibs if necessary.

Daily, After Operations

• Push the Emergency STOP button, turn the

master power switch OFF, and disconnect the machine from power.

• Vacuum/clean all chips and swarf from table,

slides, and base.

• Wipe down all unpainted or machined sur-

faces with a high-quality rust preventative.

• Loose mounting bolts or fasteners.

• Worn, frayed, cracked, or damaged wires.

• Emergency STOP button not working correctly.

• Worn or loose V-belts (see Page 50).

• Missing or open belt guards/door.

• Coolant not flowing correctly.

• Any other unsafe condition.

Cleaning &

Protecting

Regular cleaning is one of the most important steps in taking good care of this machine. In most shops, 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 it may drive them deeper into moving surfaces and could cause sharp chips to fly into your face or hands.

All visible swarf should be removed from the mill during cleaning.

Besides the ways, all other unpainted and machined surfaces should be wiped down daily to keep them rust-free and in top condition. This includes any surface that is vulnerable to rust if left unprotected (especially any parts that are exposed to water soluble coolant). Typically, a thin film of way oil is all that is necessary for protection (refer to Page 36 for way oil from Grizzly).

Lubrication

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

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.

DISCONNECT MACHINE FROM POWER before performing any lubrication task!

Important: Before adding lubricant, clean the debris and grime from the device and the immediate area to prevent contamination of the new lubricant.

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

Ball Oilers

Oi l Ty p e ......Model T23963 or ISO 32 Equivalent

Oil Amount Lubrication Frequency

Proper lubrication of ball oilers is done with a pump-type oil can that has a plastic or rubberized cone tip (see Page 36 for offerings from Grizzly). We do not recommend using metal needle or lance tips, as they can push the ball too far into the oiler, break the spring seat, and lodge the ball in the oil galley.

Push the tip of the oil can nozzle against the ball oiler to create a hydraulic seal, then pump the oil can once or twice. If you see sludge and contaminants coming out of the lubrication area, continue pumping the oil can until the oil runs clear. Move the components through the entire path of travel a few times to distribute the oil. When finished, wipe away the excess oil.

Hazards

As some coolant ages, dangerous microbes can proliferate and create a biological hazard. The risk of exposure to this hazard can be greatly reduced by replacing the old coolant on a regular basis, as indicated in the maintenance schedule.

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

BIOLOGICAL & POISON

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

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 2 gallons (7.5 liters) of fluid.

Running the coolant pump without adequate coolant in the reservoir may permanently damage the coolant pump, which will not covered by the warranty.

To check/add coolant:

1. DISCONNECT MACHINE FROM POWER!

Clean away debris and grime from the cool-

ant return screen and the surrounding area, then remove the screen from the base, as shown in Figure 64.

Coolant

Return Screen

Figure 64. Coolant return screen removed.

Use a clean metal tool as a dip stick to mea-

sure the level of coolant in the reservoir. If the level is lower than 1 1⁄2", add coolant by pouring it through the hole in the base left by the return screen.

Re-install the return screen before resuming

milling operations.

Tip: As an alternate method, leave the return

screen in place and use a clean, small instrument through the holes in the return screen as a dip stick. If more coolant is necessary, make sure the screen and surrounding area are clean from any containments, then add the coolant through the screen.

Machine Storage

The machine 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 mill remains in good condition for later use.

Note: When taking the machine out of storage, repeat the Test Run and the Spindle Break-In.

2. Place the catch pan on the table, position the coolant nozzle into the pan, then use the coolant pump to drain the reservoir.

Note: When the catch pan is near full, empty

it into a 5 gallon bucket, then repeat the process until the reservoir is empty.

Tip: Alternately, slide a rubber hose onto

the coolant nozzle and point it into 5 gallon bucket.

DISCONNECT MACHINE FROM POWER!

4. Clean away debris and grime from the cool-

ant return screen and the surrounding area, then remove the screen from the base.

Thoroughly clean out the reservoir. Make

sure the interior is completely dry before adding new coolant.

Note: Use a shop vacuum and a cleaning

solution that is compatible with type of coolant. For instance, if you are using a waterbase coolant, then use a water-base cleaning solvent. Also, use magnets to remove any metal chips left behind.

When the reservoir is clean and dry, fill the

reservoir with new coolant through the hole in the base left by the return screen.

Tip: Place a couple of magnets inside the

reservoir under the return screen to collect metal particles and keep them out of the coolant pump.

To prepare the machine for storage:

DISCONNECT MACHINE FROM POWER!

2. Lubricate the machine as directed in Lubrication, beginning on Page 41.

Clean out coolant reservoir as directed in

3. Changing Coolant on this page.

Thoroughly clean all unpainted, bare metal

surfaces, then coat them with quality rust preventative. Take care to ensure these surfaces are completely covered but 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 in place of rust preventative.

Loosen belts to prevent them from stretch-

ing during storage. Post a reminder on the machine that belts need to be re-installed or tensioned before resuming operations.

Place a few moisture-absorbing desiccant

packs inside the electrical cabinet.

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.

Re-install the return screen before resuming

milling operations.

V-Belt Service

After approximately 16 hours of use, the V-belts stretch slightly and seat into the pulleys. It is important to check and adjust them to compensate for this initial wear. Check the tension thereafter on a regular basis. If the belts become excessively worn or damaged, replace them.

All V-belts can be replaced by releasing the tension and rolling them off the pulleys, then rolling the new belts back onto the pulleys.

Note: Replace the upper horizontal spindle V-Belts as a matched pair. This will ensure even wear and power transmission.

Adjusting Gibs

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

Correctly positioning gibs is a matter of trial and error and patience. Tight gibs make table movement more accurate but stiff. Loose gibs make table movement sloppy but easier to do. The goal of gib adjustment is to remove unnecessary sloppiness without causing the ways to bind.

Many experienced machinists adjust the gibs just to the point where they can feel a slight drag in table movement.

The Z-axis gib has only one adjustment screw on the top of the gib (see Figure 70) that moves the gib up and down. Use the same method of adjustment as the other gibs with the one screw.

Note: Remove the way cover behind the table to gain access to the Z-axis gib adjustment screw.

Z-Axis

Gib Screw

Screws on each end of the gib allow gib adjustment to increase or decrease the friction between the sliding surfaces.

DISCONNECT MACHINE FROM POWER BEFORE ADJUSTING THE GIBS!

Make sure all table locks are loose. For the X- and Y-axis gibs, loosen one gib adjustment screw (see Figure 69) and tighten the opposite screw the same amount to move the gib, while at the same time rotating the handwheel to move the table until you feel a slight drag in that path of movement.

Note: Remove the way cover behind the table to gain access to the rear Y-axis gib adjustment screw.

Adjusting Leadscrew

Backlash

The X-axis leadscrew nut shown in Figure 71 is accessed from underneath the right side of the table.

Leadscrew backlash is the amount of free play movement in the leadscrew (when the leadscrew moves but the table does not) after changing the direction of rotation.

A leadscrew must have a certain amount of backlash to rotate easily, but over time, it increases with wear. Generally, 0.003"–0.006" leadscrew backlash is acceptable to ensure smooth movement and reduce the risk of premature thread wear.

The X-axis leadscrew backlash is adjusted using a long 4mm hex wrench to tighten/loosen the cap screws on the leadscrew nut. This adjusts the force the leadscrew nut exerts on the leadscrew threads.
