Additional Safety for Surface Grinders

WHEEL SPEED RATING. Wheels operated at a

faster speed than rated for may break or fly apart. Before mounting a new wheel, be sure the wheel RPM rating is equal or higher than the speed of the grinder.

WHEEL FLANGES. Only use the flanges included with the grinder when mounting wheels. Other flanges may not properly secure the wheel and could cause the wheel to fly off or break apart.

RING T EST. Perform a "ring test" on grinding wheels before installation to ensure that they are safe to use. A wheel that does not pass the ring test may break or fly apart during operation.

STARTING GRINDER. If a wheel IS damaged, it will usually fly apart shortly after start-up. To protect yourself, always stand away from the grinding wheel when turning the machine ON and allow the wheel to gain full speed before standing in front of it.

CRACKED WHEEL. Cracked wheels may break and fly apart during operation. Replace cracked wheels immediately!

PROTECTIVE CLOTHING. Protect skin from flying sparks by wearing close-fitting long sleeves and buttoned-up shirt. In case of falling heavy objects, wear leather, non-skid boots with added toe protection.

GRINDING MAGNESIUM. Grinding material with magnesium content may increase the risk of fire or explosion. Before grinding material with magnesium content, review all available safety information that pertains to grinding magnesium, including the National Fire Protection Association standard NFPA 480, “Storage, Handling and Processing Magnesium.”

WORKPIECE CONTACT. A heavy impact against the grinding wheel can cause it to break or fly apart, causing serious personal injuries. Avoid jamming the workpiece into the wheel to reduce this risk.

LUNG PROTECTION. Grinding produces hazardous dust, which may cause long-term respiratory problems if breathed. Always wear a NIOSH approved dust mask or respirator when grinding, and use coolant when possible to minimize this risk.

HAND/WHEEL CONTACT. Grinding wheels have the capability of removing a lot of skin fast. Make sure the workpiece is securely clamped to the table, then position your hands a safe distance away when grinding. Avoid wearing gloves as they may get caught in the grinding wheel and cause even more serious entanglement injuries.

DUST COLLECTION. DO NOT connect a surface grinder to a dust collection system that is used with woodworking machines. Sparks emitted from the grinding process may ignite wood particles, resulting in fire or explosion. Only use a metal-specific dust collection system with this machine.

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

EYE PROTECTION. Grinding causes small particles to become airborne at a high rate of speed. ALWAYS wear ANSI-approved eye and face protection when using this machine.

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

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:

Site Considerations

Weight Load

Physical Environment

Place this machine near an existing power source.

Shadows, glare, or strobe effects that may distract

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

Space Allocation

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

See below for required space allocation.

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

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

Electrical Installation

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

Lighting

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

or impede the operator must be eliminated.

Wheel Selection

Most grinding wheels from major manufacturers are marked in a somewhat uniform manner. Understanding these markings will help you understand the capabilities of various wheels. Always refer to the manufacturer’s grinding recommendations when selecting a wheel for your project.

The grinding wheel you choose will depend on several factors related to the operation you plan to perform. The hardness of the material you will be grinding and the surface finish you desire are the two primary factors to consider when selecting a grinding wheel.

An example of the basic format for wheel numbering is shown below. The wheel in this example is a “36A60LV”.

Grit Size

The ideal grit for an operation depends on a number of considerations. Use the table below to choose a grit suitable for your desired results.

Wheel Inspection

Ring Test

Do not assume that a wheel is in sound condition just because it is new—damage can often occur during shipping, with age, with prolonged exposure to moisture, or because of improper storage.

To inspect a wheel for damage:

1. Remove wheel flange and sleeve, then look

for any cracks, chips, nicks, or dents in wheel surface. If you see any of these, DO NOT attempt to use wheel.

2. Do a ring test. This test will give you an indication of any internal damage that may not be obvious during a visual inspection.

3. Inspect paper washers on both sides of grinding wheel (see Figure 28).

These washers are cushions between wheel

sleeve and flange and grinding wheel. Without paper washers, cracks can be spawned from center of wheel when the arbor nut is tightened. Over time, these cracks can radiate outward and the wheel may explode during operation, possibly causing injury.

This test will give you an indication of any internal damage that may not be obvious during a visual inspection.

To perform a ring test:

1. Make sure wheel that you test is clean and

dry; otherwise, you may get false results.

Note: If wheel is wet with coolant, hang it in a

dry location until it is dry (usually overnight).

2. Remove wheel flange and sleeve.

3. Hang wheel in air with a piece of cord or

string looped through wheel bore, as shown in Figure 29.

Paper Washer

Figure 28. Important wheel paper washer.

Note: If you need to replace or install new

paper washers, replacements can be cut out of any thick construction paper or card stock. Regular notebook paper or paper from a copy machine is not acceptable, as it is too thin to provide required cushion. Be sure to transfer any RPM limitations and wheel type information to the new paper washers.

-26-

Figure 29. Ring test setup.

4. At locations shown with an X in Figure 29,

gently tap wheel with a light non-metallic device such as handle of a screwdriver or a wooden mallet.

An undamaged wheel will emit a clear metal-

lic ring or “ping” sound in each of these spots. A damaged wheel will respond with a dull thud that has no clear tone. If you determine from ring test that wheel is damaged, DO NOT use it!

Model G0763 (Mfg. Since 8/13)

Wheel Balancing

4. Attach wheel sleeve and flange to wheel, as instructed in Mounting/Removing Wheel on Page 28.

An unbalanced wheel can result in a damaged wheel and poor finishes because the edge of the wheel does not contact the workpiece evenly.

Although the new wheel itself is generally balanced by the manufacturer, the addition of the sleeve and flange will require rebalancing. Additionally, the wheel can become unbalanced with wear.

Correctly balancing the wheel assembly will require trial-and-error and patience.

Note: If wheel is wet with coolant, hang it in a

dry location until it is dry (usually overnight).

2. Clean rust and debris from edges of wheel balancing base (see Figure 30).

9. Center nearest weight with line from above

step and secure it in place. This weight will remain in place during following steps.

10. Position remaining two weights evenly around sleeve groove.

11. Place wheel assembly on balancing base. Wheel assembly should not rotate if weights are in correct positions.

— If wheel assembly does rotate, reposition

two weights from Step 10 and repeat this step until wheel assembly no longer rotates when placed on balancing base.

12. When you are satisfied with wheel balancing settings, install wheel assembly on machine and test run for 5 minutes to verify balance.

— If any wobble is detected in wheel as it

rotates on machine, repeat this procedure until it does not.

13. To make sure entire width of wheel edge is parallel to table, redress wheel as instructed in Wheel Dressing on Page 31.

Wheel

Before mounting a grinding wheel (new or used), perform the following procedures:

• Wheel Inspection (Page 26)

• Ring Test (Page 26)

• Wheel Balancing (Page 27)

Do not use a wheel that is suspected of having cracks, or if you can see chips, nicks, or dents in the wheel surface. These conditions can lead to wheel failure where the wheel flies apart at operating speed. Always be sure to use a wheel that is rated for operating at speeds of at least 3450 RPM.

Wheel Dressing

Superior grinding results can only be achieved with a properly balanced and dressed wheel. Do not assume that a wheel will run true on the spindle if it is new or has not been separated from the sleeve and flange.

IMPORTANT: Balance wheel, as instructed on Page 27, before dressing it.

3. Remove arbor nut.

Note: Arbor nut has left-handed threads so it

unthreads clockwise.

4. Thread cap screw on wheel puller out and thread puller onto wheel sleeve, as shown in Figure 37.

Note: Wheel puller has standard right-hand-

ed threads and threads onto sleeve clockwise.

Wheel

Puller

Dressing the wheel correctly will save you from wasting grinding abrasive and shattering the dressing tool diamond. Additionally, with a properly balanced and dressed wheel you can rest assured that if you have finish problems, the grinding wheel is not the culprit.

Depending on the finish required, varying degrees of roughness can be obtained. For example: A fast dressing at a depth of 0.03mm will prepare a wheel surface for rough cuts; or a slow dressing with multiple light passes of the diamond at a depth of 0.01mm will prepare the same wheel for finish cuts.

Positioning is critical for the dressing tool so you will not shatter the diamond or have poor dressing results. For best results and safe use, the dressing tool must be positioned in the trailing zone of the wheel, as shown in Figure 38. If the tool is positioned on the leading side of the wheel, the diamond will be shattered or even grabbed by the wheel and drawn under the grinding wheel, causing severe damage or injury to the operator or bystanders.

5. To break taper mating between wheel sleeve

and arbor, tighten puller cap screw.

The X- and Y-axis power feeds are designed to work together. When correctly set up, the Y-axis power feed will move the table a specific distance when the table completes a side-to-side cycle along the X-axis. Eventually, the entire workpiece surface will be ground.

Refer to Figure 39 and following descriptions to become familiar with the power feed controls and their functions.

Learning to set the controls is a matter of experience, patience, and trial and error. Use the instructions below for a typical setup to understand how to use the controls to attain the desired results.

Tool Needed Qty

Hex Wrench 5mm .............................................. 1

To set up the power feeds to work together:

1. DISCONNECT MACHINE FROM POWER!

2. Position X- and Y-axis limit stops (see Figures 40–41) so that grinding wheel will

cover desired length and width of workpiece surface.

Note: When limit stops contact limit switch,

table travel will reverse.

B. X-Axis Speed Control Knob: Controls the

speed of table movement along the X-axis.

C. Y-Axis Speed Control Knob: Controls the

speed of table movement along the Y-axis.

D. Y-Axis Mode Selector Switch: Selects the

mode of operation for the Y-axis—jog (the “T”), manual (the “hand”), or automatic (the “table” symbol).

E. Y-Axis Reverse Button: Reverses the direc-

tion of Y-axis table movement.

3. Rotate both speed controls knobs all the way counterclockwise. This will prevent power feeds from starting table movement when power feed unit is turned ON.

4. Reconnect machine to power.

5. Position grinding wheel above workpiece

without making contact. This position will be used to test run limit stop setup.

6. Select automatic operation by turning X-axis mode selector switch to the right (pointing at “table” symbol).

9. Stop X-axis table travel by rotating X-axis speed control all the way counterclockwise.

10. Hold Y-axis mode selector all the way to left (pointing at “T” symbol) to jog Y-axis table movement, and make sure grinding wheel travels the desired distance over workpiece in the Y-axis.

— If grinding wheel does not travel the desired

distance over workpiece, rotate Y-axis mode selector to the center (pointing at “hand” symbol), then reposition Y-axis limit stops.

7. Turn X-axis speed control knob clockwise to slowly begin table travel.

8. Make sure grinding wheel travels desired distance over workpiece in X-axis.

— If grinding wheel does not travel desired

distance over workpiece, rotate X-axis speed control knob all the way counterclockwise to stop table travel, then reposition X-axis limit stops.

To prevent damage to power feed unit, ONLY stop table travel by rotating speed control knobs all the way counterclockwise. Do NOT use ON/OFF switch or mode selector switches to stop table travel.

11. Using the Z-axis handwheel, lower grinding

wheel until it just touches the highest point of workpiece surface.

Note: Better results are attained with multiple

light passes than a few deep passes.

12. Start coolant flow and grinding wheel rotation.

13. With both mode selector switches rotated to the right (pointing at “table” symbol), rotate the speed control knobs to the desired table travel speed.

Note: When table completes one side-to-side

cycle in X-axis path, then table will travel for a short time along the Y-axis path and stop. The distance the table travels along Y-axis path depends upon setting of Y-axis speed control knob.

You can reverse Y-axis direction any time by

pushing the Y-axis reverse button.

-32-

14. Allow the grinding wheel to surface the desired workpiece surface until there are no more sparks generated before lowering the grinding wheel with Z-axis crank for additional surfacing.

Do NOT leave machine unattended when operating in power feed mode to prevent an unexpected occurrence from damaging machine/workpiece or causing a safety hazard.

SB1365—South Bend Lathe Way Oil, 12 oz. T23962—ISO 68 Moly-D Machine/Way Oil 5-gal T23963—ISO 32 Moly-D Machine Oil 5-gal

Moly-D oils are some of the best we've found for maintaining the critical components of machinery because they tend to resist run-off and maintain their lubricity under a variety of conditions—as well as reduce chatter or slip. Buy in bulk and save with 5-gallon quantities.

T23964—Armor Plate with Moly-D MultiPurpose Grease, 14.5 oz. (NLGI#2 Equivalent)

Armor Plate with Moly-D is a rich green moly grease that provides excellent stability and unsurpassed performance under a wide range of temperatures and operating conditions. Armor Plate grease is entirely unique due to the fact that the moly in it is solubilized, which provides superior performance to other greases containing the black solid form of molybdenum disulfide.

SECTION 6: MAINTENANCE

accidental startup, always disconnect machine from

Cleaning &

To reduce risk of shock or

power before adjustments, maintenance, or service.

Schedule

To keep this machine in the best operating condition, make sure to complete the following maintenance items within the minimum intervals listed below.

Daily:

• Use/fill one-shot oiler (Page 36).

• Check/fill coolant tank.

• Check/correct loose mounting bolts.

• Check/replace damaged or cracked grinding wheel.

• Check/correct worn or damaged wires.

• Clean and protect machine.

• Correct any other unsafe condition.

Protecting

Typically, the easiest way to clean swarf from the table is to use a wet/dry shop vacuum that is dedicated for this purpose only. 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 it may drive them deeper into moving surfaces and could cause sharp chips to fly into your face or hands.

The magnetic chuck and the unpainted table surface underneath the chuck should be wiped down daily to keep them rust-free and in top condition. Then apply a thin film of ISO 32 oil to provide protection (see Page 34 for an offering from Grizzly).

Monthly:

• Drain oil sump (Page 36).

• Lubricate table ball bearing strips (Page 36).

• Check/change coolant (Page 37).

-34-

Model G0763 (Mfg. Since 8/13)

Lubrication

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.

One-Shot Oiler

Type ............Model T23963 or ISO 32 Equivalent

Amount .............................................. 1–2 Pumps

Lubrication Frequency ...... 4–8 Hrs. of Operation

The one-shot oiler provides lubrication to the vertical leadscrew, the cross feed ways, and the cross feed leadscrew.

Oil Sump

As the one-shot oiler sends oil to the cross feed ways, any excess oil will exit tubes in the rear and drain into a sump in the column. Check and drain the sump at least once a month to avoid overflow.

To drain the oil sump, use a 10mm hex wrench to remove the drain plug on the rear of the column (see Figure 46).

To use the one-shot oiler, pull the pump handle out (see Figure 45) and push it back in with moderate force. Move the grinding head up and down a few times through the full Z-axis path to distribute the oil on the leadscrew. Do the same with the Y-axis handwheel.

Table Ball Bearing Strips

Type ......................T23964 or NLGI#2 Equivalent

Amount .............................................. As Needed

Lubrication Frequency .............................Monthly

To lubricate table ball bearing strips:

1. DISCONNECT MACHINE FROM POWER!

2. Remove table to expose ball bearing strips

(see Figure 47).

Ball Bearing Strips

Figure 47. Table ball bearing strips exposed.

3. Use mineral spirits, stiff brush, and shop rags

to clean old grease and grim from strips, saddle ways, and table ways.

Coolant System

Hazards

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

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

BIOLOGICAL & POISON

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

4. When dry, apply a medium coat of NLGI#2

grease to strips.

5. Re-install table.

6. Move table back and forth several times to

distribute lubrication.

A small amount of coolant is lost during normal operation. Check the coolant tank 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.

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

-36-

Model G0763 (Mfg. Since 8/13)

Check/Adding Coolant

Lift the coolant tank lid shown in Figure 48 to check the coolant level. If necessary, add coolant until the level is a couple of inches from the top of the tank.

The coolant tank holds approximately 8 gallons of fluid.

Wheel Storage

Store grinding wheels in a dry area that is not subject to extreme temperature changes or freezing. Some abrasive bonds may be adversely affected by excessive humidity, dampness, or extreme temperature changes.

Store the wheels on edge (vertically) in racks that provide a cushioned two-point cradle support to prevent rolling. Also, provide partitions that prevent the wheels from tipping over.

Use a high-quality, water-soluble oil coolant that is non-flammable. Generally, synthetics last longer.
