Machine Description

The Model G0751 is a fully-featured drill press that strikes a great balance between being heavy-duty and high-precision.

The spindle is fully reversible, features both coarse and fine downfeed controls, tapping controls that can be set for repeatable production, and a digital read out. The six spindle speeds range from 90–1970 RPM and are controlled by convenient levers in an oil-bath-lubricated and gear-driven headstock.

The headstock tilts 90° left/right and moves in the Z-axis on a massive column. The table features a built-in recycling coolant system, movement in all three paths, and rotation around the column so the workpiece can be mounted on the base for those really big jobs.

Additional Safety for Drill Presses

To avoid loss of drilling

Serious injury or death can occur from getting clothing, jewelry, or long hair entangled in rotating spindle or bit/cutting tool. Contact with rotating bit/cutting tool can result in severe cuts or amputation of fingers. Flying metal chips can cause blindness or eye injuries. Broken bits/ cutting tools, unsecured workpieces, chuck keys, or other adjustment tools thrown from rotating spindle can strike nearby operator or bystanders with deadly force. To reduce the risk of these hazards, operator and bystanders MUST completely heed hazards and warnings below.

EYE/FACE/HAND PROTECTION. Flying chips

created by drilling can cause eye injuries or blindness. Always wear a face shield in addition to safety glasses. Always keep hands and fingers away from drill bit/cutting tool. Avoid awkward hand positions, where a sudden slip could cause hand to move into bit/cutting tool.

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

REMOVING ADJUSTMENT TOOLS. Chuck key, wrenches, and other tools left on machine can become deadly projectiles when spindle is started. Remove all loose items or tools used on spindle immediately after use.

CORRECT SPINDLE SPEED. Using wrong spindle speed can cause bits/cutting tools to break and strike operator or bystanders. Follow recommended speeds and feeds for each size/type of bit/cutting tool and workpiece material.

SECURING BIT/CUTTING TOOL. Firmly secure bit/cutting tool in chuck so it cannot fly out of spindle during operation or startup.

DRILLING PREPARATION. control or bit breakage, only drill into a flat surface that is approximately perpendicular to bit. Clear table of all objects before starting spindle. Never start spindle with bit pressed against workpiece.

SECURING TABLE AND HEADSTOCK. To avoid loss of control leading to accidental contact with tool/bit, tighten all table and headstock locks before operating drill press.

WORKPIECE CONTROL. An unsecured workpiece may unexpectedly shift, spin out of control, or be thrown if bit/cutting tool “grabs” during operation. Clamp workpiece to table or in tablemounted vise, or brace against column to prevent rotation. NEVER hold workpiece by hand during operation. NEVER start machine with bit/cutting tool touching workpiece; allow spindle to gain full speed before drilling.

INSPECTING BIT/CUTTING TOOL. Damaged bits/cutting tools may break apart during operation and hit operator or bystanders. Dull bits/cutting tools increase cutting resistance and are more likely to grab and spin/throw workpiece. Always inspect bits/cutting tools for sharpness, chips, or cracks before each use. Replace dull, chipped, or cracked bits/cutting tools immediately.

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.

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.

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: 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.)

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 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:

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

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).

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

The unpainted surfaces of your machine are coated with a heavy-duty rust preventative that prevents corrosion during shipment and storage. This rust preventative works extremely well, but it will take a little time to clean.

Be patient and do a thorough job cleaning your machine. The time you spend doing this now will give you a better appreciation for the proper care of your machine's unpainted surfaces.

There are many ways to remove this rust preventative, but the following steps work well in a wide variety of situations. Always follow the manufacturer’s instructions with any cleaning product you use and make sure you work in a well-ventilated area to minimize exposure to toxic fumes.

Before cleaning, gather the following:

• Disposable rags

• Cleaner/degreaser (WD•40 works well)

• Safety glasses & disposable gloves

• Plastic paint scraper (optional)

Basic steps for removing rust preventative:

Cleanup

Gasoline and petroleum products have low flash points and can explode or cause fire if used to clean machinery. Avoid using these products to clean machinery.

Put on safety glasses.

Coat the rust preventative with a liberal

amount of cleaner/degreaser, then let it soak for 5–10 minutes.

Wipe off the surfaces. If your cleaner/degreas-

er is effective, the rust preventative will wipe off easily. If you have a plastic paint scraper, scrape off as much as you can first, then wipe off the rest with the rag.

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.

The machine must be fully assembled before it can be operated. Before beginning the assembly process, refer to

7. handwheel (J) to control spindle travel.

Tapping Downfeed

Tapping downfeed allows the downward spiraling of the tap to control spindle travel. The depth is controlled by adjusting the tapping limit stops (C) in relation with the tapping limit switches (D).

Note: Use the fine downfeed graduated dial

(I) and the attached thumb screw to measure the relative amount of spindle travel.

Auto-Downfeed

The auto-downfeed feature uses headstock gears to control powered downfeed in rates of 0.004,

0.007, and 0.010 inches per spindle revolution.

To use auto-downfeed:

Make sure spindle is completely stopped.

2. Loosen depth graduated dial lock handle (G).

This will disengage depth graduated dial from the operation.

Rotate auto-downfeed ON/OFF knob (A) to

ON position.

Rotate auto-downfeed rate selector knob (B)

clockwise to desired downfeed rate.

5. Loosen coarse handle lock-down thumb screw (E) and pull coarse downfeed handles (F) away from headstock.

Rotate mode selection switch on control

panel to Drilling/Milling position.

To use tapping downfeed:

Make sure spindle is completely stopped.

2. Rotate the auto-downfeed ON/OFF and auto-

downfeed rate selector knobs to the OFF position.

Adjust depth graduated dial (H) to allow for

maximum spindle travel and tighten depth graduated dial lock handle (G) to secure it.

Push coarse downfeed handles (F) toward

headstock and tighten coarse handle lockdown thumb screw (E) to hold them in place.

Use a 5mm hex wrench to adjust tapping limit

stops (C) in relation to tapping limit switches (D).

— The shorter limit stop is used to reverse

spindle rotation when desired depth is reached. This will happen when this limit stop contacts outer limit switch.

— The longer limit stop is used to stop spindle

rotation for repetitive operations. This will happen when this limit stop contacts inner limit switch. Adjust limit stop in relation to inner limit switch so that spindle rotation stops when the tap is no longer engaged with workpiece.

When using auto-downfeed, the spindle will not automatically stop or reverse when it reaches the bottom depth of travel. To avoid machine damage, manually stop spindle rotation before this happens.

7. Start spindle forward rotation to engage the

auto-downfeed.

When desired depth of spindle travel is

reached, stop spindle travel.

Push coarse downfeed handles toward head-

stock and use them to return spindle to top.

Model G0751 (Mfd. Since 07/15)

Rotate mode selection switch on control

panel to Tapping position.

Note: Position tap just slightly above the

workpiece when the spindle is at the top most position. This will prevent the tap breaking when spindle rotation is started.

Start spindle forward rotation.

8. Use coarse downfeed handles to slowly lower

tap into workpiece until it engages workpiece and the downward spiraling action of tap controls spindle travel, then release manual pressure on coarse downfeed handles.

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 operation, 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 21.

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 R P M H 2

1970 RPM H 3

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

Figure 21. 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.

With the spindle completely stopped, position the spindle range and speed levers (see Figure 22) 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 power before adjustments,

maintenance, or service.

Schedule

For optimum performance from this machine, this maintenance schedule must be strictly followed.

Daily:

• Check/repair loose mounting bolts.

• Check/replace damaged tooling.

Check/repair worn or damaged wires.

•

Clean debris and built up grime off of machine.

•

Check/resolve any other unsafe condition.

•

Cleaning &

Protecting

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 31 for offerings from Grizzly).

Every 8 Hours of Operation:

• Check/add headstock oil (Page 34).

Lubricate table ball oilers (Page 35).

•

• Lubricate dovetail ways (Page 35).

• Lubricate downfeed gears (Page 36).

• Check/add coolant (Page 38).

Every 40 Hours of Operation:

• Lubricate quill and column surfaces (Page 36).

Lubricate table leadscrews (Page 37).

•

Every 90 Days of Operation:

Lubricate quill rack and pinion (Page 37).

•

• Lubricate column racks (Page 38).

Model G0751 (Mfd. Since 07/15)

Lubrication

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

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.

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 checking the coolant regularly, 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.

When dry, use a brush to apply a thin coat of grease to the teeth, then raise/lower the headstock and table to distribute the grease.

Note: Re-apply oil to the column smooth surfaces that was removed during the cleaning process.

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 1⁄2 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.

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 it increases with wear over time. 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 47 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 46) 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 the operation requires that the spindle axis be precisely perpendicular to the table, the spindle must be trammed 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) 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.

.............. 1

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 48.

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.

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 49 for an example).

Spindle

— 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.

Retighten tilting hex nuts.

Rotate spindle by hand so that the indicator

point rests on one end of parallel block, as illustrated in Figure 50, then zero dial.

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.

Mark slot on cover that engages the roll pin at

the top—this is the factory setting.

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 51) 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.
