Machine Description

The metal lathe is used to remove material from a rotating workpiece, which is held in place on the spindle with a chuck or faceplate. The cutting tool is mounted on the carriage or tailstock and moved against the spinning workpiece to perform the cut.

Models G0602/Z and G0752/Z all require setting gearbox dial positions and positioning V-belts to select the spindle speed. However, the Model G0752/Z features an electronic variable-speed control and digital RPM display that make it possible to select speeds within the selected range while the machine is running.

Model G0602Z and G0752Z are both indentical to their non-"Z" counterparts, but the Z models are equipped with an included X/Z-Axis DRO.

may damage the wires inside. Do not handle

WEARING PROPER APPAREL. Do not wear loose clothing, gloves, neckties, 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 rec-

ommended 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

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 Metal Lathes

mize toxicity, change coolant regularly. When

To reduce risk of

Serious injury or death can occur from getting entangled in, crushed between, or struck by rotating parts on a lathe! Unsecured tools or workpieces that fly loose from rotating objects can also strike nearby operators with deadly force. To minimize the risk of getting hurt or killed, anyone operating this machine MUST completely heed the hazards and warnings below.

CLOTHING, JEWELRY & LONG HAIR. Tie back

long hair, remove jewelry, and do not wear loose clothing or gloves. These can easily get caught on rotating parts and pull you into lathe.

ROTATING PARTS. Always keep hands and body at a safe distance from rotating parts—especially those with projecting surfaces. Never hold anything against rotating workpiece, such as emery cloth, that can pull you into lathe.

GUARDING. Guards and covers protect against entanglement or flying objects. Always ensure they are properly installed while machine is running.

ADJUSTMENT TOOLS. Remove all chuck keys, wrenches, and adjustment tools before turning lathe ON. A tool left on the lathe can become a deadly projectile when spindle is started.

SAFE CLEARANCES. Before starting spindle, verify workpiece has adequate clearance by handrotating it through its entire range of motion.

NEW SETUPS. Test each new setup by starting spindle rotation at the lowest speed and standing to the side of the lathe until workpiece reaches full speed and you can verify safe rotation.

SPINDLE SPEEDS. Using spindle speeds that are too fast for the workpiece or clamping equipment can cause rotating parts to come loose and strike nearby people with deadly force. Always use slow spindle speeds with large or non-concentric workpieces. Never exceed rated RPM of the chuck.

LONG STOCK SAFETY. Long stock can whip violently if not properly supported. Always support any stock that extends from the chuck/headstock more than three times its own diameter.

CLEARING CHIPS. Metal chips can be razor sharp. Avoid clearing them by hand or with a rag. Use a brush or vacuum instead.

SECURE WORKPIECE. An improperly secured workpiece can fly off spindle with deadly force. Make sure workpiece is properly secured before starting the lathe.

CHUCKS. Chucks can be heavy and difficult to hold. During installation and removal, protect your hands and precision bed ways by using a chuck cradle or piece of plywood over the bed ways. Use lifting equipment, as necessary, for large chucks.

STOPPING SPINDLE. Always allow spindle to completely stop on its own, or use a brake, if provided. Never put hands or another object on a spinning workpiece to make it stop faster.

CRASHING. A serious explosion of metal parts can occur if cutting tool or other lathe component hits rotating chuck or a projecting part of workpiece. Resulting metal fragments can strike nearby people and lathe will be seriously damaged. To reduce risk of crashing, ALWAYS release automatic feeds after use, NEVER leave lathe unattended, and CHECK all clearances before starting lathe.

COOLANT SAFETY. Coolant can become very toxic through prolonged use and aging. To mini-

using, position nozzle properly to avoid splashing operator or causing a slipping hazard on floor.

TOOL SELECTION. Cutting with incorrect or dull tooling increases risk of injury from broken or dislodged components, or as a result of extra force required for operation. Always use sharp tooling that is right for the job.

SANDING/POLISHING. To reduce risk of entanglement, never wrap emery cloth around rotating workpiece. Instead, use emery cloth with the aid of a tool or backing board.

MEASURING WORKPIECE.

entanglement, never measure rotating workpieces.

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

or equipment damage may occur if machine is not properly grounded and connected to 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 specified circuit requirements.

For your own safety and protection of

Note: Circuit requirements in this manual apply to

a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, consult an electrician or qualified service personnel to ensure 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.)

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

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

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

Extension cords cause voltage drop, which can 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 be in good condition and contain a ground wire and matching plug/receptacle. Additionally, it must meet the following size requirements:

Site Considerations

Weight Load

Refer to the 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.

Physical Environment

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,

Place this machine near an existing power source. Make sure all power cords are protected from traffic, material handling, moisture, chemicals, or other hazards. Make sure to leave enough space around machine to disconnect power supply or

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

Lifting & Placing

HEAVY LIF T! 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.

Do not attempt to lift or move this lathe without using the proper lifting equipment (such as forklift or crane) or the necessary assistance from other people. Refer to Needed for Setup on Page 16 for details.

To lift and move the lathe:

1. Remove the shipping crate top and sides,

then remove the chip pan, 4-jaw chuck, faceplate, and toolbox from the shipping pallet.

Wrap the lifting straps around the bed and

between the leadscrew and the bedway, as shown in Figure 17, to help prevent bending the leadscrew during lifting.

Figure 17. Example of lifting strap positions.

Attach the lifting straps to the power lifting

equipment, have an assistant steady the load, then lift it just enough to clear any obstacles and move it to its mounting position.

Properly mount the lathe as instructed in the

7. Mounting subsection on Page 21.

Position the chip pan on the selected mount-

ing surface and use it as a template to mark the hole locations for the mounting hardware (refer to Leveling & Mounting on Page 21).

Unbolt the lathe from the shipping pallet.

Only use lifting straps and power lifting equipment rated for at least 500 lbs. and in good working condition. If the lathe falls or tips over while moving it, serious personal injury and property damage could result.

To balance the load for lifting, move the

tailstock and carriage to the extreme right end of the bedway, then lock them in place.

Note: Before attempting to move the car-

riage, make sure the carriage lock is loose and the half nut is disengaged.

-20-

Model G0602/Z, G0752/Z (Mfd. Since 05/24)

Leveling & Mounting

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

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

Leveling

Leveling machinery helps precision components,

such as bedways, remain straight and at during

the lifespan of the machine. Components on a machine that is not level may slowly twist due to the dynamic loads placed on the machine during operation.

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

See the gure below for an example of a high

precision level.

Mounting

The chip pan and the base of the lathe have holes that allow the machine to be mounted to a workbench. You MUST mount your machine to a workbench to prevent it from unexpectedly moving during operation, which could lead to personal injury or property damage.

Follow these guidelines when mounting your lathe to ensure safe and accurate cutting results:

• Make sure that the workbench can adequately support the weight of the machine and materials and that it will not move or vibrate during operation.

• Use a silicon sealant between the lathe and the chip pan to prevent coolant or other fluids from leaking through onto the bench or floor.

To mount the lathe and chip pan to the workbench, drill holes all the way through the workbench, and use hex bolts, washers, and hex nuts to secure the lathe to the workbench, as illustrated in Figure 19.

Congratulations! The test run is complete. Turn the lathe OFF and perform the following Spindle Break-In procedure.

-23-

Spindle Break-In

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

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

Recommended

Adjustments

For your convenience, the adjustments listed below have been performed at the factory. However, because of the many variables involved with shipping, we recommend that you at least verify the following adjustments to ensure the best possible results from your new machine. Step-bystep instructions for these adjustments can be found on the pages referenced below.

Important: Do not perform the break-in procedure independently from the Test Run section—serious damage could occur to the lathe if the controls are set differently than instructed in that section.

To perform the spindle break-in:

Operate the lathe at 150 RPM for 10 minutes.

2. G0602/G0602Z: Repeat Step 1 at each of

the following speeds 300, 560, 720, 1200, and 2400.

G0752/G0752Z: Repeat Step 1 at each of

the following approximate speeds: 800, 1300, and 2000.

When the spindle has come to a complete

using machine.

To complete a typical operation, the operator does the following:

Puts on safety glasses, rolls up sleeves,

removes jewelry, and secures any clothing, jewelry, or hair that could get entangled in moving parts.

Examines the workpiece to make sure it is

suitable for turning, then securely mounts the workpiece in a chuck, between centers, or on the faceplate.

Mounts the tooling, aligns it with the workpiece,

then backs it away to establish a safe startup clearance.

Clears all setup tools from the lathe.

5. Checks for safe clearances by rotating the

workpiece by hand at least one full revolution.

. Sets the correct spindle speed for the opera-

tion.

To reduce risk of eye injury from flying chips always wear safety glasses or face shield when operating.

If you are not experienced with this type of machine, WE STRONGLY RECOMMEND that you seek additional training outside of this manual. Read books/magazines or get formal training before beginning any projects. Regardless of the content in this section, Grizzly Industrial will not be held liable for accidents caused by lack of training.

Installation &

Mounting

This lathe is equipped with a threaded spindle nose. With this type of spindle, a chuck or faceplate is screwed directly onto the spindle nose.

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

Loose hair, clothing, or jewelry could get caught in machinery and cause serious personal injury. Keep these items away from moving parts at all times to reduce this risk.

Removal Devices

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

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

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

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

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

4-Jaw Chuck

Refer to the Chuck Installation (see Page 27) and Chuck Removal (see Page 28) instructions to install or remove the 4-jaw chuck.

5. Tighten each jaw in small increments. After

you have adjusted the first jaw, continue tightening the remaining jaws in an opposing sequence, as shown by the sequential order in Figure 33.

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

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

2. Place a chuck cradle or plywood on the

bedway below the chuck to protect the bedway surfaces.

3. Use the chuck key to open each jaw so the

workpiece will lay flat against the chuck face, jaw steps, or into the spindle opening.

With help from another person or a holding

device, position the workpiece so it is centered in the chuck.

Faceplate

Refer to the Chuck Installation (see Page 27) and Chuck Removal (see Page 28) instructions to install or remove the faceplate.

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

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

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

To mount a non-concentric workpiece to the faceplate:

DISCONNECT LATHE FROM POWER!

2. Protect the bedway with a piece of plywood.

3. With help from another person or a holding

device to support the workpiece, position it onto the faceplate and clamp it in place with a minimum of three independent clamping devices (see Figure 35 for an example).

Be sure to take into account the rotational

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

Tailstock

The tailstock (see Figure 36) is typically used to support long workpieces by means of a live or dead center (refer to Centers on Page 36). It can also be used to hold a drill or chuck to bore holes in the center of a part. Custom arbors and tapers can also be cut on your lathe by using the offset tailstock adjustment.

Aligning Tailstock to Spindle Centerline

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

Note: As long as this dead center remains in

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

4. Install a center in the tailstock.

Attach a lathe dog to the test stock from Step

5. 2, then mount it between the centers (see Figure 42 for an example).

Live Centers

A live center (not included) has bearings that allow the center tip and the workpiece to rotate together; it can be installed in the tailstock quill for higher speeds.

Mounting Dead Center in Spindle

1. DISCONNECT LATHE FROM POWER!

2. Thoroughly clean and dry all threads and

mating surfaces of the spindle bore and the center, making sure that no lint or oil remains on these surfaces.

Note: This will prevent the tapered surfaces

from seizing due to operational pressures, which could make it very difficult to remove the center.

Mount a chuck or faceplate onto the spindle,

whichever is correct for your operation.

The spindle taper is an MT#4 and will only receive the MT#4 dead center. The tailstock quill taper is an MT#3 and will only receive the MT#3 dead centers.

Dead Centers

A dead center is a one-piece center that does not rotate with the workpiece and is used to support long, slender workpieces in the tailstock.

A carbide-tipped dead center (not included) can better withstand the effects of friction than a typical dead center and is best used in the tailstock where the workpiece will rotate against it. The tip of a dead center must be generously lubricated during the operation to avoid premature wear and maximize smooth operation. Using low spindle speeds will also reduce the heat and wear from friction.

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

Insert the center into the spindle bore through

the chuck or faceplate.

Figure 46 shows an example photo of a dead

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

Removing Center from Spindle

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

Mounting Center in Tailstock

The included dead center or a live center can be used in the tailstock. Mounting instructions are the same for both. Figure 47 shows an example photo of a dead center mounted in a tailstock.

3. Use the quill handwheel to feed the quill out of the casting approximately 1" (see Figure

1).

Note: The maximum quill travel is 21⁄2", but

we do not recommend extending the quill more than 2" or stability and accuracy will be reduced.

Figure 47. Example photo of using a dead

center installed in the tailstock.

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

To mount a center in the tailstock:

DISCONNECT LATHE FROM POWER!

2. Thoroughly clean and dry the tapered mating

surfaces of the tailstock quill bore and the center, making sure that no lint or oil remains on the tapers.

Figure 1. Dead center inserted into tailstock.

Insert the center into the tailstock quill.

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

Note: Only apply enough pressure with the

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

Secure the quill lock lever and tailstock lock

nut.

Removing Center from Tailstock

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

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

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

Below are two common methods:

• Move the tailstock center over the cross slide and use a dial indicator to measure the distance from the surface of the cross slide to the tip of the center. Adjust the cutting tool height so it is the same distance above the cross slide as the tailstock center.

Align the tip of the cutting tool with a tailstock

Spindle Speed

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

Setting Spindle Speed

Selecting one of the available six spindle speeds (Model G0602/G0602Z) or one of the three spindle speed ranges (Model G0752/G0752Z) is performed by repositioning the V-belt(s) between the pulleys.

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

Determining Spindle Speed

Many variables affect the optimum spindle speed to use for any given operation, but the two most important are the recommended cutting speed for the workpiece material and the diameter of the workpiece, as noted in the formula shown in Figure 57.

Use a low RPM when machining heavy eccentric workpieces; securely clamp your workpiece and remove the chuck key! Objects thrown from a lathe can cause serious injury or death to the operator or bystanders.

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

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

The books Machinery’s Handbook or Machine Shop Practice, and some internet sites, provide excellent recommendations for which cutting speeds to use when calculating the spindle speed. These sources also provide a wealth of additional information about the variables that affect cutting speed and they are a good educational resource.

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

press the ON button.

Adjust the spindle speed dial until the spindle

speed display reads 150 RPM.

The carriage has power feed capability when it is engaged with the lead screw. The rate that the carriage moves (feed rate) is controlled by V-belt, change gear, and gearbox dial configurations.

Feed rate and spindle speed must be considered together when determining the proper cutting speed for a given workpiece. The sources you use to determine the optimum spindle speed for an operation will also provide the optimal feed rate to use with that spindle speed.

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

The carriage can alternately be driven by the leadscrew for threading operations. However, this section only covers using the power feed option for the carriage for non-threading operations. To learn how to power the carriage for threading operations, refer to Threading on Page 46.

SECTION 6: MAINTENANCE

Daily, After Operations

• Turn the spindle direction switch to STOP,

Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury.

and press the Emergency STOP button (to prevent accidental startup).

• Vacuum/clean all chips and swarf from bed and slides.

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

• Add oil to the ball oilers (Page 53).

Schedule

Ongoing

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

• Loose mounting bolts or fasteners.

• Worn, frayed, cracked, or damaged wires.

• Guards or covers removed.

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

• Damaged or malfunctioning components.

Daily, Before Operations

• Check/add gearbox oil (Page 52).

• Add oil to the ball oilers (Page 53).

• Clean/lubricate the leadscrew and carriage rack (Page 54).

• Lubricate the bedways (Page 54).

• Compound slide (Page 54).

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

• Ensure carriage lock bolt is loose.

Annually

• Change the gearbox oil (Page 52).

• Lubricate the change gears (Page 55).

• Check/level bedway (Page 21).

Cleaning/Protecting

Because of its importance, we recommend that the cleaning routine be planned into the workflow schedule.

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

All 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 parts that are exposed to water soluble cutting fluid). Use a quality rust protectorate such as SLIPIT Boeshield

to prevent corrosion.

Model G0602/Z, G0752Z (Mfd. Since 05/24)

Lubrication

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

................................1 or 2 Squirts/Fill

................................. Daily

This lathe has 10 ball oilers that should be oiled on a daily basis before beginning operation.

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

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

Refer to Figures 82–86 to identify the location of each ball oiler.

Figure 89. Change gears.

To lubricate the change gears:

DISCONNECT LATHE FROM POWER!

Open the change gear cover and remove all

the change gears shown in Figure 89.

Clean the change gears thoroughly with min-

eral spirits to remove the old grease. Use a small brush if necessary to clean between the teeth.

Clean the shafts, and wipe away any grease

splatters in the vicinity and on the inside of the change gear cover.

Using a clean brush, apply a thin layer of

grease on the gears. Make sure to get grease between the gear teeth, but do not fill the teeth valleys.

Install the change gears and mesh them

together with 0.003"–0.008" backlash. Once the gears are meshed together, apply a small dab of grease between them where they mesh together—this grease will be distributed when the gears rotate and re-coat any areas scraped off during installation.

To handle and care for the change gears:

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

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

7. Close the change gear cover before re-con-

necting the lathe to power.

Model G0602/Z, G0752Z (Mfd. Since 05/24)

Machine Storage

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

To prepare the lathe for storage:

Run the lathe and bring the gearbox reservoir

to operating temperature, then drain and refill with clean oil.

DISCONNECT LATHE FROM POWER!

3. Thoroughly clean all unpainted, bare metal

surfaces, then apply a liberal coat of way oil, heavy grease, or rust preventative. Take care to ensure these surfaces are completely covered but that the rust preventative or grease is kept off of painted surfaces.

5. Loosen or remove all belts so they do not

become stretched during the storage period. (Be sure to place a maintenance note near the power button as a reminder that the belts have been loosened or removed.)

Cover the lathe and place it in a dry area that

is out of direct sunlight and away from hazardous fumes, paint, solvents, or gas. Fumes and sunlight can bleach or discolor paint.

Every few months do the following:

Rotate by hand all gear-driven components

• a few times in several gear selections. This will keep the bearings, bushings, gears, and shafts well lubricated and protected from corrosion—especially during the winter months.

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

Lubricate the machine as outlined in the

4. Lubrication section beginning on Page 52.

Be sure to use an oil can to purge all ball oilers and oil passages with fresh oil.

Backlash Adjustment

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

Reducing backlash to less than 0.002" is impractical and can lead to accelerated wear to the leadscrew and other components. Avoid the temptation to overtighten the backlash nut or screw while adjusting.

The cross slide backlash is adjusted by loosening the cap screw shown in Figure 91. The screw pushes down on a wedge and forces the leadscrew nut apart, taking up lash between the nut and leadscrew.

Cap Screw

The compound rest backlash is adjusted by loosening or tightening the nut and set screw shown in Figure 90 to remove play between the handwheel and the leadscrew collar.

To adjust the backlash, loosen the compound rest nut and set screw, turn the handwheel counterclockwise until the compound rest moves, then tighten the nut until the backlash is approximately

0.002"–0.003", as indicated on the graduated dial. Tighten the set screw to secure the setting.

Figure 91. Cross slide backlash adjustment cap

screw.

To adjust the backlash, remove the compound rest. Then, rock the cross slide handwheel back and forth, and tighten the cap screw slowly until the backlash is approximately 0.002"–0.003" as indicated on the graduated dial.

If you end up adjusting the nut too tight, loosen the cap screw, turn the handwheel back and forth until it turns freely—then try again.

Re-install the compound rest when you are finished.

Gib Adjustment

The goal of adjusting the cross slide and compound slide gibs is to remove sloppiness or "play" from the ways without making them overly stiff and difficult to move.

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

Note: Turning the set screws clockwise will

tighten the gib, and turning them counterclockwise will loosen the gib.

When you are satisfied with the gib adjust-

ment, keep the set screws from moving and re-tighten the hex nuts to secure the settings.

Re-check the movement of the slide and, if

Half Nut Adjustment

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

Leadscrew Shear Pin

Replacement

The longitudinal leadscrew is secured to the feed rate gearing in the headstock with the use of a soft-metal shear pin (see Figure 95). The shear pin is designed to break and disengage power to the leadscrew to help protect more expensive lathe components if you crash your carriage or take too large of a cut and overload the lathe.

Contact Grizzly Customer Service at (570) 5469663 to order a replacement shear pin (Part # P0602815).

Shear Pin

Loosen the two adjustment hex nuts shown

in Figure 94, then adjust the set screws in small, even increments so one end of the gib does not become tighter than the other.

Half-Nut

Adjustment

Fasteners

Figure 94. Typical half nut gib adjustment.

4. Engage/disengage the half nut several times

and notice how it feels. The adjustment is correct when the half nut has a slight drag while opening and closing. The movement should not be too stiff or too sloppy.

Repeat Steps 3–4, if necessary, until you are

satisfied with the half nut pressure.

While keeping the set screws from moving,

re-tighten the hex nuts, then re-install the thread dial.

2. Rotate the leadscrew so the shear pin faces

up and down. If the connecting collar rotates independently from the leadscrew, then rotate the collar so the shear pin holes align with those in the leadscrew.

Use the punch and hammer to drive out the

pieces of the old shear pin.

Make sure the holes in the collar and

leadscrew are aligned, then tap the new shear pin completely through the holes in the collar and leadscrew.
