Machine Description

The Model G0755 is a free-standing mill/drill that strikes a great balance between being heavy-duty and high-precision.

The spindle is equipped with precision P5 spindle bearings and is driven by an oil-bath-lubricated and gear-driven headstock. The spindle is fully reversible and features both coarse and fine downfeed controls. The six spindle speeds range from 90–1970 RPM and are controlled by convenient gear-change levers.

The headstock tilts 90° left/right and moves in the Z-axis along precision dovetailed ways—with both manual and powered elevation control. The table also features both manual and powered X-axis control, but with a manually-controlled Y-axis. All table movement is along scraped dovetail ways.

Additional Safety for Mill/Drills

UNDERSTANDING CONTROLS. Make sure you

understand the use and operation of all controls before starting the mill/drill.

SAFETY ACCESSORIES. To reduce the risk of injury from flying chips, always use a face shield in addition to safety glasses when using the mill/drill.

CL E AN - U P. Metal chips can cut your hands. DO NOT clear chips by hand or compressed air that can force the chips farther into the machine. Use a brush or vacuum, and never clear chips while the spindle is turning.

SECURING TOOLING. Objects that are thrown by the spinning action of the mill/drill can be deadly missiles. Always firmly secure the cutting tool before starting the machine. Always remove the chuck key, drawbar wrench, and any tools immediately after use.

CUTTING TOOL INSPECTION. Inspect cutting tools for sharpness, chips, or cracks before each use. Replace dull, chipped, or cracked cutting tools immediately. Handle cutting tools with care. Leading edges are very sharp and can cause lacerations.

STOPPING SPINDLE. Serious injury may occur if you try to stop the moving spindle by hand. DO NOT stop the spindle using your hand or any other object. Allow the spindle to stop on its own.

WORK HOLDING. A workpiece that moves unexpectedly during operation can be ejected from the machine, causing personal injury or property damage. Before starting the machine, be certain the workpiece is properly clamped to the table. NEVER hold the workpiece by hand during operation.

MACHINE CARE AND MAINTENANCE. Never operate the mill/drill with damaged or worn parts that can break apart during operation. Maintain your mill/drill in proper working condition. Perform routine inspections and maintenance promptly. Put tools away after use.

MAINTENANCE/ADJUSTMENTS. To avoid possible electrocution or physical injury, make sure the mill 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.

SPINDLE SPEEDS. For safe and good results, select the spindle speed that is correct for the type of work and material. Allow the spindle to reach full speed before beginning a cut.

POWER DISRUPTION. In the event of a local power outage during operation, turn spindle switch OFF to avoid a possible sudden start up 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 decrease the risk of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur.

No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious personal injury, damage to equipment, or poor work results.

Model G0755 (Mfg. Since 1/13)

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.

Serious injury could occur if you connect

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

Lifting & Placing

get help from other people

HEAV Y LIFT! Straining or crushing injury may occur from improperly lifting machine or some of its parts. To reduce this risk,

and use a fork lift (or other lifting equipment) rated for weight of this machine.

Power lifting equipment, steel rods (refer to Page 11), and at least two other people are required to lift and place the mill.

4. Insert steel rods into holes in stand, as shown in Figure 5.

Steel Rods

To move your machine into position:

1. Remove outside crating material from ship-

ping crate, but leave machine bolted to pallet (for now).

2. Move machine next to its intended installation location, then unbolt it from pallet.

3. To help balance machine during moving, position table as close to column as possible, and adjust headstock to its lowest position.

Figure 5. LIfting setup.

5. Evenly position forklift forks under steel rods

on each side of cabinet.

Note: Before next step, make sure all locks

are tight to avoid sudden shifts which could unbalance machine.

6. With help of additional people to steady load, slowly lift machine, remove pallet, then lower machine into position.

Model G0755 (Mfg. Since 1/13)

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.

Anchoring to Floor

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.

Anchoring to Concrete Floors

Assembly

Except for the handwheel handles, the mill/drill was fully assembled at the factory.

Use a slotted screwdriver to attach the handwheel handles, as shown in Figure 7.

Joining Drill Chuck

& Arbor

Lubricating Mill/Drill

An arbor is included for the drill chuck that comes with this machine. The following procedure describes how to install the arbor in the chuck.

After the arbor is installed in the drill chuck, it is very difficult to separate the assembly. If you would like to use a different chuck in the future, we recommend obtaining a new arbor.

Important: DO NOT install the drill chuck and arbor assembly into the spindle until AFTER the test run.

To join the drill chuck and arbor:

1. Use acetone or lacquer thinner to clean drill

chuck and arbor mating surfaces, especially the bore.

2. Retract chuck jaws completely into chuck.

3. Insert small end of arbor into chuck.

GEARBOX MUST

BE FILLED WITH OI L!

OIL MAY NOT BE

SHIPPED WITH MACHINE!

Refer to Lubrication Section

for Correct Oil Type.

The headstock oil reservoir must be properly filled with oil before the mill/drill can be operated for the first time.

Damage caused by running the mill/drill without the proper amount of oil in the reservoir will not be covered under warranty. Refer to the Lubrication section, beginning on Page 30, for details on how to check and add oil.

4. Hold assembly by the arbor and tap chuck onto a block of wood with medium force, as illustrated in Figure 8.

Figure 8. Tapping drill chuck/arbor on block of

Spindle Speed

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

1. DISCONNECT MACHINE FROM POWER!

2. Remove drawbar cap, and only unthread

drawbar from tool holder one full rotation.

Note: Do not fully unthread tool holder from

drawbar, or drawbar and tool holder threads could be damaged during the next step.

3. Tap top of drawbar with hammer to unseat taper.

4. Hold onto tool holder with one hand and fully unthread drawbar with the other hand.

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 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 the formula shown in Figure 26.

*Recommended

Cutting Speed (FPM) x 12

Tool Dia. (in inches) x 3.14

Spindle

Speed (RPM)

*Double if using carbide cutting tool

Figure 26. Spindle speed formula for mill/drills.

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.

Model G0755 (Mfg. Since 1/13)

Setting Spindle Speed

The chart below explains how to position the spindle range and speed levers to set the desired spindle speed.

Spindle Speed Range Lever Speed Lever

90 RPM L 1

210 RPM L 2

345 RPM L 3

670 RPM H 1

118 0 RPM H 2

1970 RPM H 3

Change spindle speed ONLY when the spindle is completely stopped. Otherwise, machine damage could occur.

With the spindle completely stopped, position the spindle range and speed levers (see Figure 27) to set the spindle speed.

Note: If the levers will not move to the desired position, rotate the spindle by hand while applying pressure on the lever. When the gear teeth align, the lever will move into place.

SECTION 6: MAINTENANCE

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

Cleaning and

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 tooling.

• 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 31).

• Lubricate ball oilers (Page 32).

• Lubricate table/column ways and quill (Page

32).

Metal chips left on the machine 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 27 for offerings from Grizzly).

Lubrication

An essential part of lubrication is cleaning the components before lubricating them.

Every 40 Hours of Operation:

• Lubricate table leadscrews (Page 33).

Every 90 Days of Operation:

• Lubricate quill rack and pinion (Page 33).

• Lubricate Z-axis leadscrew (Page 34).

Annually:

• Change headstock oil (Page 31).

-30-

This step is critical because grime and chips build up on lubricated components, which makes them hard to move. Simply adding more lubricant will not result in smooth moving parts.

Clean all exterior components in this section with mineral spirits, shop rags, and brushes before lubricating.

DISCONNECT MACHINE FROM POWER BEFORE PERFORMING LUBRICATION.

NOTICE

Follow reasonable lubrication practices as outlined in this manual. Failure to do so could lead to premature failure of your machine and will void the warranty.

Proper lubrication of ball oilers (shown in Figures 45–46) is done with a pump-type oil can that has a plastic or rubberized cone tip (see Page 27 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.

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.

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!

Adjusting Leadscrew

Backlash

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

Leadscrews 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- and Y-axis leadscrew backlash is adjusted using a long 4mm hex wrench to tighten/ loosen the cap screw on the leadscrew nut. This adjusts the force the leadscrew nut exerts on the leadscrew threads.

The X-axis leadscrew nut shown in Figure 54 is accessed from underneath the left side of the table.

Make sure all table locks are loose. Then, loosen one gib adjustment screw (see Figure 53) and tighten the opposing 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.

Tramming Spindle

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

Tools Needed Qty

Dial Indicator (with at least 0.0005" resolution) . 1

Indicator Holder (mounted on quill/spindle) ....... 1

Precision Parallel Block (1-2-3 Blocks) .............. 1

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.

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 55.

Spindle

Table

Figure 55. Spindle centerline properly trammed

to the table.

Note: Keep in mind that the top surface of your workpiece will not likely be exactly parallel with the table top. Depending on your operation, you may choose to tram the spindle to the top surface of the workpiece after it is mounted instead of tramming to the table.

Z-Axis

X-Axis

To tram the spindle with the table:

1. DISCONNECT MACHINE FROM POWER!

2. Prepare machine by performing the following

tasks:

— Stone table to remove all nicks and burrs,

then clean off all debris. Verify table is clean by running your hand over the top of it.

— Position table for the operation you intend

to perform after tramming—preferably centered with saddle.

— Tighten any table locks that should be tight

during intended milling operation.

3. Place parallel block underneath spindle.

4. Install indicator holder into spindle or onto

quill, then mount indicator onto it so that the point is as parallel to the block as possible (see the illustration in Figure 56 for an example).

Note: If you must re-position quill to accom-

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

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.

Brushes

The X-axis power feed motor has a carbon brushes that will wear with normal use. There is one on the top of the power feed (see Figure 58) and one on the bottom.

6. Rotate spindle by hand so that the indicator point rests on one end of parallel block, as illustrated in Figure 57, then zero dial.

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

— If indicator dial still reads zero or is within

the acceptable variance, continue on with Step 8.

— If indicator dial has moved from zero

beyond the acceptable variance, you will need to compensate for that amount by tilting head left or right. Repeat Steps 6–7 until you are satisfied with 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.

If, over time, the power feed starts to seem sluggish or will not operate, check the carbon brushes. If they are less than with new ones (Part No. P0755501-6).

Note: For proper performance, replace both carbon brushes at the same time.

Use a flat screwdriver to unthread (turn counterclockwise) the cap covering the carbon brush, replace the brush assembly, then secure it with the cap.

Tightening Return

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.

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 the roll pin at the top—this is the factory setting.

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

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 counterclockwise to fit the roll pin in the next slot.
