Additional Safety for Mill/Drills

The primary risks of operating a mill are as follows: You can be seriously injured or killed by getting clothing, jewelry, or long hair entangled with rotating cutter. You can be severely cut or have fingers amputated from contact with the rotating cutter. 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:

UNDERSTAND ALL CONTROLS. 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.

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

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.

PROPERLY SECURE CUTTER. Firmly secure cutting tool or drill bit so it does not fly out of spindle during operation.

USE CORRECT SPINDLE SPEED. 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.

INSPECT CUTTING TOOL. Inspect cutting tools for sharpness, chips, or cracks before each use. Replace dull, chipped, or cracked cutting tools immediately.

ALLOW SPINDLE TO STOP. To minimize your risk of entanglement, always allow spindle to stop on its own. DO NOT stop spindle using your hand or any other object.

PROPERLY SECURE WORKPIECE. 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.

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.

PROPERLY MAINTAIN MACHINE. Keep machine in proper working condition to help ensure that it functions safely and all guards and other components work as intended. Perform 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 all moving parts have come to a complete stop before changing cutting tools or starting any inspection, adjustment, or maintenance procedure.

POWER DISRUPTION. In the event of a local power outage during operation, turn spindle switch OFF to avoid a possible sudden startup once power is restored.

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 lessen the possibility of operator injury. If normal safety precautions are overlooked or ignored, 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 electrician 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.)

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.

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:

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.

Serious injury could occur if you connect

process. DO NOT connect to power until

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).

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.

Lifting & Placing

Another option is a "Direct Mount" (see example below) where the machine is secured directly to the workbench with lag screws and washers.

The base of this machine has mounting holes that allow it to be fastened to a workbench or other mounting surface to prevent it from moving during operation and causing accidental injury or damage.

The strongest mounting option is a "Through Mount" (see example below) where holes are drilled all the way through the workbench—and hex bolts, washers, and hex nuts are used to secure the machine in place.

Bench Mounting

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.

To lift and place machine into position:

1. Move shipping crate next to workbench or

stand, then unbolt machine from pallet.

2. Move machine work table as close to column as possible, and raise headstock to its highest position. This will help balance machine when moving.

Using Spindle

Downfeed Controls

The Model G0795 is equipped with coarse and fine spindle downfeed controls as shown in Figure 14. Coarse downfeed is typically used with drilling operations, and fine downfeed is typically used with milling operations.

Coarse

Fine

Downfeed

Handwheel

Downfeed

Handle

Fine Downfeed

To engage the fine downfeed, turn the downfeed selector knob clockwise until tightened. When fine downfeed is engaged, the spindle only moves up or down when the handwheel is rotated (there is no automatic spindle return to the top position, as with the coarse downfeed controls). This manual level of control makes it easy to precisely lock the spindle height in place with the quill lock lever when milling a flat surface across the face of a workpiece, to ensure the spindle height does not move until the entire milling operation is complete.

The graduated dial measures spindle movement in 0.001" increments, with one full revolution equaling 0.10" of spindle travel.

Using Fine Downfeed Controls

The fine downfeed handwheel allows for a precise amount of material to be removed from the workpiece.

Downfeed

Quill Lock

Selector

Knob

Coarse Downfeed

When coarse downfeed is engaged, pull handles downward to lower the spindle. An internal coil spring will raise the spindle back up when you stop applying downward pressure on the handle.

Note: To maintain control of the upward spindle travel and the rotating bit in your workpiece, always continue holding the handle until the spindle returns to the top position. Letting go of the coarse downfeed handles when the spindle is in the lowered position will cause the spindle to retract too quickly and slam up into the headstock or lift the workpiece and cause it to spin out of control.

In the following example, the fine downfeed controls are used to mill 0.010" off a workpiece:

1. Use headstock elevation crank (see Figure 16 on next page) to adjust cutting tool just

above workpiece surface, then secure the headstock with Z-axis lock levers.

2. Tighten downfeed selector knob (see Figure

14) to engage fine downfeed handwheel.

3. Loosen quill lock lever.

4. Rotate fine downfeed handwheel clockwise

and lower cutting tool so it just touches workpiece.

5. Move workpiece out of the way.

6. Using graduated dial to gauge spindle move-

ment, rotate fine downfeed handwheel clockwise 0.010".

The coarse downfeed hub features a graduated dial that measures spindle movement in 0.001" increments, with one full revolution equaling 0.10" of spindle travel.

Setting 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 spindle speed levers to produce the required 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 the formula shown in

Figure 24.

Setting Spindle Speed

Use the chart below or the one on the headstock when setting the spindle speed. With the spindle completely stopped, position the high/low range and spindle speed knobs as indicated by the spindle speed chart (see Figure 25) to set the desired spindle RPM.

Note: If necessary, rotate the spindle a little by hand to mesh the gears when changing speeds.

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.

Using Tapping Mode

8. Apply any appropriate tapping fluid to contact

point on workpiece.

When the mode switch is set to "Ta p," the spindle rotates clockwise as the tap is lowered into the predrilled hole in the workpiece. Once the depth stop is reached, the spindle automatically changes directions and rotates counterclockwise to unthread the tap from the hole.

Important: Pilot holes must be drilled prior to beginning any tapping operation.

To use the tapping mode:

1. DISCONNECT MACHINE FROM POWER!

2. Clamp workpiece to work table.

3. Install tap.

4. Select spindle speed of 115 RPM (see Setting Spindle Speed on Page 26, if necessary).

5. Loosen quill lock lever and downfeed selector

knob until coarse downfeed handle moves up and down freely.

9. Connect machine to power.

10. Rotate mode switch to "Tap."

11. Press "Left" button to engage spindle.

12. Using coarse downfeed handle, slowly lower

tap into hole until tap begins threading into workpiece. Release the coarse downfeed handle, allowing tap to travel downward on its own.

Tap will self-thread until the depth stop is

reached. When depth stop is reached, spindle rotation will automatically reverse and tap will unthread from hole.

13. Turn machine OFF.

SECTION 6: MAINTENANCE

To reduce risk of shock or accidental startup, always disconnect machine from

Cleaning &

Protecting

power before adjustments, maintenance, or service.

Schedule

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

Daily Check:

• Loose mounting bolts.

• Damaged saw blade.

• Worn or damaged wires.

• Clean debris and built up grime off of machine.

• Any other unsafe condition.

Every 8 Hours of Operation:

• Check/add headstock oil (Page 34).

• Lubricate ball oilers (Page 35).

• Lubricate table and column ways (Page 35).

• Lubricate quill outside surface (Page 36).

Every 40 Hours of Operation:

• Lubricate table leadscrews (Page 36).

Metal chips left on the machine that have been soaked with water-based coolant will invite oxidation and a gummy residue build-up around the moving parts. Use a brush and shop vacuum to remove chips and debris from the working surfaces of the mill/drill. Never blow off the mill/drill with compressed air, as this will force metal chips deep into the mechanisms and may cause injury to yourself or bystanders.

Remove any rust build-up from unpainted cast iron surfaces of your mill/drill and treat with a nonstaining lubricant after cleaning.

Keep unpainted cast iron surfaces rust-free with regular applications of ISO 68 way oil (see Page 28 for offerings from Grizzly).

NOTICE

The recommended lubrication is based on light-to-medium usage. Since lubrication helps to protect value and operation of machine, these lubrication tasks may need to be performed more frequently than recommended, depending on usage.

Every 90 Hours of Operation:

• Lubricate column leadscrew, nut, and pinion gear (Page 37).

• Lubricate quill rack and pinion (Page 37).

Annually:

• Change headstock oil (Page 34).

Model G0795 (Mfd. Since 02/15)

Failure to follow reasonable lubrication practices as instructed in this manual could lead to premature failure of machine components and will void the warranty.

Adjusting Gibs

The gibs affect the accuracy of the work table by restricting slide movements along their ways.

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

The goal of gib adjustment is to remove unnecessary sloppiness without causing binding in the dovetail ways. Tight gibs make the movements more accurate, but harder to perform. Loose gibs make the movements sloppy, but easier to perform. Many experienced machinists adjust the gibs until there is just a slight drag in table movement.

Adjusting Leadscrew

Backlash

Tool Needed Qty

Hex Wrench 4mm (long) .................................... 1

Leadscrew backlash is the amount of free-play movement in the leadscrew (when changing the direction of rotation) before the attached device begins to move.

Leadscrews must have a certain amount of backlash, but over time, this will increase with normal wear. Generally, 0.003"–0.006" leadscrew backlash is acceptable to ensure smooth movement and reduce the risk of premature thread wear.

DISCONNECT MACHINE FROM POWER BEFORE ADJUSTING THE GIBS!

Make sure all table locks are loose. Then, loosen one gib adjustment screw (see Figure 57) and tighten the opposing screw the same amount to move the gib, while at the same time using the handwheels to move the table until you feel a slight drag in that path of movement.

Y-Axis Gib Screw

(1 of 2)

X-Axis Gib Screw

(1 of 2)

The X- and Y-axis leadscrew backlash is adjusted by using a long hex wrench to tighten/loosen the cap screw on the leadscrew nut. This adjusts the force that the split leadscrew nut exerts on the leadscrew threads.

The X-axis leadscrew nut shown in Figure 58 is accessed from underneath the left side of the table.

The Y-axis leadscrew nut is similar and is accessed from underneath the machine base.

Tightening Return

Eye injury hazard! Always

Spring Tension

The return spring moves the spindle back up when the coarse downfeed handles are released. The tension of this spring was adjusted at the factory, but it may need to be tightened during the life of the mill/drill.

Important: Do not perform this procedure unless it is absolutely necessary. The high amount of spring tension involved can make this a difficult procedure. Return spring tension is adjusted at the factory and should be suitable for most applications.

If the return spring should come loose from the spring cap and rapidly unwind, laceration or impact injuries could occur. Always

wear safety glasses when using this machine.

wear heavy leather gloves and safety glasses when adjusting the return spring tension.

To adjust the return spring tension:

1. DISCONNECT MACHINE FROM POWER!

2. Wipe off any oil on spring cover so it does not

slip when you hold it during adjustments.

3. Mark slot on cover that engages roll pin—this is the factory setting.

4. Put on heavy leather gloves to protect your hands from lacerations if spring uncoils during next step.

Note: Keep a good grip on spring cover dur-

ing next step. Letting go of cover when roll pin is not engaged will cause spring to rapidly uncoil.

5. While holding spring cover against side of headstock so spring will not unwind, loosen

thumb screw approximately

⁄4".

6. Pull cover out just enough to disengage it with roll pin, then rotate it clockwise to engage roll pin in next slot in cover.

7. Retighten thumb screw to secure setting.

During this procedure, you will loosen the spring cover thumb screw (see Figure 59) just enough to pull the cover back to clear the roll pin, then rotate the cover clockwise to fit the roll pin in the next slot.

Tramming Spindle

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

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!

This procedure involves mounting a dial test indicator to the quill or spindle, rotating it around the table, and adjusting the spindle axis (Z-axis) 90° to the table X- and Y-axis, as illustrated in Figure 60.

Spindle

Z-Axis

Y-Axis

Figure 60. Spindle Z-axis perpendicular to the

table X- and Y-axis.

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

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

2. Prepare mill for tramming by performing following tasks:

• Verify the table is clean by running your

hand over the top of it. If necessary, stone the table to remove all nicks and burrs, then clean off all debris.

• Position the table for the milling operation

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

• Tighten the quill lock lever used during

intended milling operations.

3. Place parallel block underneath spindle.

4. Install indicator holder in spindle or on quill,

then mount indicator so that point is as parallel to block as possible (see Figure 61).

5. To measure spindle alignment along X-axis, place parallel block directly under spindle and indicator across length of table, as illustrated in Figure 62.

Note: If you must re-position the quill or the

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

Note: Keep one of the rotation lock bolts

just snug so the head does not move loosely while you adjust it. Remember to tighten all the rotation lock bolts after adjusting the head.

8. Place parallel block directly under spindle and across width of table, as illustrated in Figure 63.

Note: Your general goal in the next steps

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

6. Rotate spindle by hand so that indicator point rests on one end of parallel block, as illustrated in Figures 61–62, then zero the dial.

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

— If the indicator dial still reads zero or is

within the acceptable variance, continue on with Step 8.

— If the indicator dial has moved from zero

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

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

— If the indicator dial still reads zero or is

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

— If the indicator dial has moved from zero

beyond the acceptable variance, you will need to compensate for that amount by tilting the head forward or backward. Repeat Steps 9–10 until you are satisfied with the spindle axis alignment along the table Y-axis.

Note: Keep one of the tilt lock bolts just snug

so the head does not move loosely while you adjust it. Remember to tighten all the tilt lock bolts after adjusting the head.
