Additional Safety Instructions For Surface Grinders
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.
Like all power tools, there is danger associat­ed with the Model G5963 Surface Grinder. Use the tool with respect and caution to lessen the possibility of mechanical damage or operator injury. If normal safety precautions are over­looked or ignored, serious personal injury may occur.
1. Ensure that the machine sits firmly on the floor before use. Any “wobbles” must be corrected by shimming or blocking before operation.
2. This machine is not designed to process any other material except metals.
3. Never position fingers or hands directly between the grinding wheel and the table.
4. Do not operate surface grinder with cracked or damaged grinding wheels.
5. Always use extreme care in handling grind­ing wheels during installation. Always “ring check” the wheel to determine possible damage.
6. Ensure that the surface grinder is properly adjusted before using.
7. Never load or unload the workpiece while the grinding wheel is rotating or the table is moving.
8. If using coolants for grinding, always read and understand the user information listed on the coolant container. Some coolants used for machining may be hazardous to your health if not used and stored properly.
9. This manual is intended to familiarize you with this grinding machine. It is not, nor was it ever intended to be, a comprehen­sive training manual.
Operation of this equipment has the potential to propel debris into the air which can cause eye injury. Always wear safety glasses or gog­gles when operating equipment. Everyday glasses or reading glasses only have impact resistant lenses, they are not safety glasses. Be certain the safety glasses you wear meet the appropriate standards of the American National Standards Institute (ANSI).

SECTION 2: CIRCUIT REQUIREMENTS
110V Operation
The motor supplied with the G5963 can be oper­ated at either 110V or 220V. The motor comes prewired for 110V. If you wish to operate at 220V, refer to the section at right.
Under normal use, the motor draws approximate­ly 7.4 amps @ 110V. We recommend a 15 amp circuit breaker for 110V operation. This should be satisfactory for normal use, while providing enough protection against motor damage caused by power surges.
Grizzly recommends that the circuit you use should be dedicated, (i.e., the G5963 should pro­vide the only draw from that circuit). If frequent circuit failures occur when using the Surface Grinder, contact our Service Department or your local electrical contractor.
220V Operation
The G5963 Surface Grinder motor can be rewired to operate at 220V. Refer to the wiring diagram supplied with this manual. If converting to operate at 220V, the 110V plug must be replaced with a 220V plug. Plugs and receptacles can be pur­chased at your local hardware store or home cen­ter. The type of plug you choose will depend upon the type of 220V outlet used in your installation. See Figure 2 for a typical plug and outlet. This plug must be rated for at least 15 amp draw.
It is not necessary to change the switch supplied with the G5963 for 220V operation.
Under normal 220V use, the motor draws approx­imately 3.7 amps. We recommend a 10 amp cir­cuit breaker or a 10 amp slow-blow fuse.
Figure 1. Typical 110V plug and outlet.
Figure 2. Typical 220V plug and outlet.
-6- G5963 Surface Grinder
We do not recommend the use of extension cords on 220V equipment. It is much better to arrange the placement of your equipment and the installed wiring to eliminate the need for exten­sion cords. Should it be necessary to use an extension when operating at 110V, make sure the cord is rated Hard Service (grade S) or better. Refer to the chart in Section 1: Safety Instructions to determine the minimum gauge for the exten­sion cord. The extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords when they become worn or damaged.
Extension Cords
This equipment must be grounded. Please ensure that this machine is continuously grounded from the motor to the machine frame and then to a known ground. Verify that any existing electrical outlet and circuit you intend to plug into is actually grounded. If it is not, it will be necessary to run a separate 12 A.W.G. copper grounding wire from the outlet to a known ground. Under no circumstances should the grounding pin from any three-pronged plug be removed. Serious personal injury may occur.
We have covered some basic electrical requirements for the safe operation of your Surface Grinder. These requirements are not necessarily comprehensive. You must be sure that your particular electrical configuration complies with local and state codes. Ensure compliance by checking with your local munic­ipality or a licensed electrician.
Grounding
In the event of an electrical short, grounding reduces the risk of electric shock by providing a path of least resistance to disperse electric cur­rent. This tool is equipped with a power cord hav­ing an equipment-grounding conductor. See Figure 1 and 2. The outlet must be properly installed and grounded in accordance with all local codes and ordinances.
Check Motor Rotation
After the machine is assembled and properly connected to electrical power, test the motor rota­tion. Cycle the machine on and observe the rota­tion of the grinding wheel. Make sure it rotates in the direction indicated by the arrow on the wheel guard. If it does not, the wiring may not be prop­erly connected at the motor. Disconnect from the power source, and check that the motor wiring agrees with the wiring diagram provided in this manual. Make necessary adjustments, close the motor cover, reconnect to power, and test again.

Clean Up
The unpainted surfaces are coated with a waxy oil to protect them from corrosion during ship­ment. Remove this protective coating with a sol­vent cleaner or degreaser such as Grizzly’s G7895 Citrus-based Degreaser. Avoid chlorine­based solvents as they may damage painted sur­faces should they come in contact. Always follow the usage instructions on the product you choose for clean up.
Follow the safety rules listed below when work­ing with solvents.
1. Read and follow all directions and warn­ings on the solvent label.
2. Work only in a well ventilated area.
3. Do not work near any type of open flame (e.g., pilot lights, kerosene heaters, and so on).
4. DO NOT smoke while working with flam­mable material.
5. Paper towels from the cleaning process are extremely combustible. Dispose of waste towels so they do not create a fire hazard.
Site Considerations
FLOOR LOAD
Your G5963 Surface Grinder represents a large weight load in a small footprint. Most commercial floors are suitable for the Model G5963. Some residential floors may require additional support to accommodate both machine and operator.
WORKING CLEARANCES
Working clearances can be thought of as the dis­tances between machines and obstacles that allow safe operation of every machine without limitation. Consider existing and anticipated machine needs, size of material to be processed through each machine, and space for auxiliary stands and/or work tables. Also consider the rel­ative position of each machine to one another for efficient material handling. Be sure to allow your­self sufficient room to safely run your machines in any foreseeable operation.
LIGHTING AND OUTLETS
Lighting should be bright enough to eliminate shadow and prevent eye strain. Electrical circuits should be dedicated or large enough to handle combined motor amp loads. Outlets should be located near each machine so power or exten­sion cords are not obstructing high-traffic areas. Be sure to observe local electrical codes for prop­er installation of new lighting, outlets, or circuits.
Many of the solvents commonly used to clean machinery can be highly flammable, and toxic when inhaled or ingested. Always work in well­ventilated areas far from potential ignition sources when dealing with solvents. Use care when disposing of waste rags and towels to be sure they do not create fire or environmental hazards. Keep children and animals safely away when cleaning and assembling this machine.
Make your shop “child safe”. Ensure that your workplace is inaccessible to youngsters by closing and locking all entrances when you are away. Never allow visitors in your shop when assembling, adjusting or operating equipment.
-10- G5963 Surface Grinder
This surface grinder is heavy and awkward to move. We recommend that you use the proper equipment to put the surface grinder into posi­tion in your shop or on a mobile base. Lifting without proper equipment or ample assistance could result in serious injury.
SECTION 4: ASSEMBLY
Lifting the Grinder
The majority of the weight of the Surface Grinder is the grinding head. Take great care when lifting this unit from the crate and moving it into position on the stand. Remove the table from the crate first and set it aside until the grinder is complete­ly secured to the stand.
This grinding head unit is very heavy, approxi­mately 400 lbs. There is a lifting eye on the top of the upper unit which can be used with a chainfall or hoist to lift the unit into position. See Figure 3. Do not push on the upright sliding mechanism or get it jammed in any way during movement. This can damage the ways or the cross feed screw if too much pressure is applied to the upright.
Mounting on Stand
Locate the stand as close to its final position as possible. Position the grinding head on the stand, lining up the four holes in the stand with the holes in the base of the head. Use four hex bolts, wash­ers and nuts provided to secure the head to the stand.
Once the head is secured to the stand, loosen the bolt on the back of the upright. This allows the counterweight to move freely (it is locked into position for shipping purposes). This bolt can be completely removed or left in position should the weight need to be locked for future movement.
With the stand in its final location, adjust the lev­eling pads to bring the unit to a level position, making sure there are no wobbles or vibration in the assembly. In some cases, it may be useful to bolt the unit to the floor, or to put vibration isola­tion dampers underneath the feet of the stand to avoid vibration. The more solid the mounting of the unit is, the better the results that can be achieved in the grinding process.
Figure 3. Lifting upper unit with chain hoist.
G5963 Surface Grinder -11-
Handwheel Handles
Table and Handwheel
There are two handwheels which control cross feed and vertical movement. The handles for these handwheels need to be threaded in the hole in the outer edge of the wheel face.
Wipe the V-grooves of the table and the saddle down with way oil (Mobil Vactra #2 or equivalent). The table rests by its own weight on the ways, and is oiled by the lubrication system. Set the sliding table in position on the saddle. Make sure the gear on the underside of the table engages with the gear on the handwheel shaft.
Thread the three spokes of the handwheel onto the hub, and tighten the jam nuts. Turn the hand­wheel back and forth to make sure the table moves freely.
The table dogs should be in position to stop the left and right movement of the table. Test these to make sure the travel is limited so there is no chance of moving the table too far in one direc­tion. See Figure 4.
Guard
Attach the Guard to the left hand side of the table using the socket head cap screws provided. This guard helps to contain debris coming off the rotating wheel during the grinding operation.
Figure 4. Table dogs limit table travel.

DO NOT make adjustments while the surface grinder is running. Ensure that the switch is off, power is disconnected and moving parts have stopped before making adjustments. Failure to comply could result in serious injury or electri­cal shock hazard.
SECTION 5: OPERATIONS
Overview
Once assembly has been completed, the G5963 Surface Grinder is ready for use in the shop.

Wheel Mounting
Before mounting any wheel, check it for integrity by performing a “ring check”. Balance the wheel on one finger, then lightly tap the rim of the wheel with a piece of wood such as the handle of a hammer. The wheel should have a ringing or har­monic type of sound. If it responds with a dull thud it may indicate that the wheel has cracks. Do not use a wheel which is suspected of having cracks, or if there are visual chips, nicks or dents in the wheel surface. These discontinuities can lead to wheel failure where the wheel flies apart at operating speed. Always be sure to use a wheel which is rated for operating at speeds of 3450 RPM.
Figure 6. Cross-section of wheel assembly.
To mount the wheel (Refer to Figure 6):
1. Remove the wheel guard by unscrewing the three cap screws holding the cover in place.
2. With the Pin Wrench engaged in the two holes on the face of the Wheel Sleeve Nut, hold the spindle in position. Use the Adjustable Wrench on the Spindle Nut and loosen, keeping in mind that this is a left­hand thread.
3. If the wheel does not pull easily off of the taper, tap the end of the spindle lightly with a wooden or rubber mallet to loosen the wheel. Slide the wheel off of the taper.
Aluminum oxide and silicon carbide wheels are marked in a somewhat uniform manner by all the major manufacturers. 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 basic format for wheel numbering is:
Prefix Abrasive Grit Grade Bond
Type Size Type
36 A 60 L V
The most common abrasive types used are A for Aluminum Oxide and C for Silicon Carbide, and occasionally SG for seeded gel. The prefix is the manufacturer’s designation for a particular type.
The grit size is a number referring to the size of the abrasive grain in the wheel. The lower the number the coarser the wheel - 10 is a very coarse wheel for roughing and 220 is usually the upper range for fine finish work.
Grade is an indication of the hardness of the wheel, with A being softest to Z the hardest.
Bond Type refers to the type of bonding material used to hold the abrasive material. Most general purpose wheels will have a V indicating Vitrified clay is used, providing a high strength and good porosity. The other most common is B for resin where synthetic resins are used. These are used to grind cemented carbide and ceramic materials
There may be other numbers inserted which have meaning for a particular type of wheel. Refer to the manufacturer’s technical data for a complete explanation.
Wheel Selection
-14- G5963 Surface Grinder
The wheel and sleeve assembly should be bal­anced before mounting onto the Grinder. Generally the wheel itself will be balanced by the manufacturer. The Wheel Sleeve has Balance Weights positioned in a groove which can be moved to accomplish final balance of the assem­bly.
1. Mount the wheel on the sleeve assembly as described in the Wheel Mounting sec­tion. Position the weights so they are even­ly spaced around the groove.
2. Mount the wheel on the Balance Arbor, which has a taper the same as that on the machine spindle. Tighten the nut on the arbor to lock the wheel in place.
3. Place the arbor across two parallel, level bars so the wheel is freely suspended. The wheel will turn until the heaviest side is down. Mark the heavy side with a chalk mark.
4. Loosen the setscrew on one of the Balance Weights opposite the chalk mark, and move it so it is 180˚ opposite the chalk mark.
5. Place back on the bars and observe whether one side is still heavy. It may be necessary to repeat Steps 3 - 5 several times until the wheel is balanced. When the arbor does not roll across the bars at all, then the wheel is in balance.
6. Remove the wheel from the Balance Arbor. Make sure the Balance Weight setscrews are firmly secured. Install wheel in the grinder.
Make certain the wheel has a tight fit on the Wheel Sleeve, and that the Sleeve Nut and Spindle Nut are properly tightened on the Spindle. Improper assembly of the grinding wheel can cause failure of the wheel which can result in a wheel breaking apart and causing injury from flying debris. Always have the Wheel Guard installed, even when test running the machine.
4. Remove the Wheel Sleeve from the back side of the wheel.
5. Take the new grinding wheel and insert the Wheel Sleeve into the bore from the back of the wheel. Most wheels will have a paper disc on each side, this helps to equalize the clamping pressure. Do not remove these discs! The Wheel Sleeve should fit snugly in the bore of the wheel. If it is too loose, do not attempt to fill the gap with any other types of material. The wheel will not main­tain proper balance. If it is too tight, do not attempt to force the wheel onto the Sleeve, as it may cause cracking of the wheel.
6. Thread the Wheel Sleeve Nut onto the opposite side of the wheel. Tighten enough to get a good seat on the sleeves against the paper discs, this helps to assure the wheel will not slip in operation. Do not over­tighten, however, as this can cause stress on the wheel.
7. Slide this assembled wheel onto the spin­dle, making sure the wheel sleeve hole and the spindle taper are clean and free of any foreign material, dents or nicks.
8. Tighten the Spindle Nut using the Pin Wrench to hold the Sleeve and the Adjustable Wrench to tighten the Nut. Do not overtighten.
9. Replace the Wheel Guard and secure with three cap screws.
10. Run the wheel at full speed for at least one minute before doing any grinding. If there is a structural problem with the wheel, it will generally occur during the initial runup.
Wheel Balancing
G5963 Surface Grinder -15-
Dressing is performed on the face of the grinding wheel to sharpen the abrasives or to remove material which has imbedded in the surface. Dressing also makes the circumference of the wheel true to its centerpoint, thus insuring good grinding results. Wheels should always be dressed when first installed on the machine, and also periodically as the wheel is used. The fre­quency will depend upon the types of materials being ground, and the severity of the grinding operations. A wheel which will not balance prop­erly may need to be dressed to true first to assure concentricity.
1. Insert the Dressing Diamond into the Dressing Fixture and attach the fixture to the table so that it is just right of the center line of the grinding wheel. See Figure 7.
Figure 7. Dressing fixture mounted on magnetic chuck.
2. Lower the Vertical Adjustment Handwheel so the grinding wheel just comes in contact with the Dressing Diamond.
3. Move the Cross Feed Handwheel so the Dresser is in front of the wheel. Make cer­tain there is no movement of the Longitudinal Handwheel during the dress­ing operation.
4. Turn the grinder on and let the wheel spin for at least one minute. Then advance the Cross Feed so the Dresser sweeps across the wheel. Lower the wheel .001" and repeat. Continue successive passes until the entire edge of the wheel is being cut. A better finish will result if the last couple of passes are less than .001".
5. Turn the machine off and remove the Dressing Fixture.
Wheel Dressing
-16- G5963 Surface Grinder
NOTICE
If a cut is taken that is too large, the surface grinder will bog down noticeably. The motor may even stall. If this happens, turn off the power immediately. Re-adjust the wheel height to allow a lighter cut and repeat the operation.
Typical Operation
Operation of the grinder is controlled through the location and movement of the three handwheels. The Vertical Adjustment Handwheel controls the up and down movement of the grinding head. It is generally this axis which governs the amount of stock removal which will take place. Never attempt to remove too much material in one pass, much better results can be achieved with multiple passes.
The Cross Feed Handwheel controls the front to back movement of the table. When grinding a large surface, it will be necessary to sweep the wheel over the surface, then move the table, then take another sweep. Repeat this process until the entire surface is ground. See Figure 9.
The Table Travel Handwheel (the one with the three spokes) moves the table from left to right. This allows the ability to traverse the part back and forth underneath the grinding wheel.
Figure 9. Grinding multiple pieces.
DO NOT make adjustments while the surface grinder is running. Ensure that the switch is off, power is disconnected and moving parts have stopped before making adjustments. Failure to ensure that power is disconnected could result in serious injury or electrical shock hazard.
Figure 8. One-shot oil lubrication pump.
Oil Pump
The critical components of the machine are lubri­cated by means of the oil pump located on the left hand side of the machine. See Figure 8. Check the oil level periodically. Add new oil (Use a Way Oil such as Mobil Vactra #2 or equivalent) as needed to maintain the fluid level in the Oil Pump.
Pull the handle of the Pump out. Do not attempt to push it back in! The pump handle will slowly return to its original position as the lubricant is dispensed. Operate the Oil Pump at the start of each day the grinder is used. The grinding wheel does not need to be turned on for the Oil Pump to work.
G5963 Surface Grinder -17-
Once the assembly is complete and the adjust­ments are done to your satisfaction, you are ready to test the machine.
Turn on the power supply at the main panel. Press the START button. Make sure that your fin­ger is poised on the STOP button, just in case there is a problem. The surface grinder should run smoothly, with little or no vibration or rubbing noises. Strange or unnatural noises should be investigated and corrected before operating the machine further.
Test Run
NOTICE
Before starting any grinding job, run the sliding table back and forth with the motor off! Check to make sure there will be adequate clear­ances between the wheel and the holding fix­tures or portions of the part which are not intended to be ground.
Operation of this equipment has the potential to propel debris into the air which can cause eye injury. Always wear safety glasses or gog­gles when operating equipment. Everyday glasses or reading glasses only have impact resistant lenses, they are not safety glasses. Be certain the safety glasses you wear meet the appropriate standards of the American National Standards Institute (ANSI).

Accessories
In order to properly use this machine it is necessary to purchase some type of holding fixture. The workpiece must be firmly secured before beginning any type of grinding operations. Refer to the current Grizzly cata­log for options. The most versatile holding device is a magnetic chuck. See Figure 10. With the throw of a lever anything magnetic can be firmly attached to the table without having jaws or fingers which might inter­fere with the grinding wheel.
Some types of grinding will also be aided by the addi­tion of some type of lubricant or coolant. These can be introduced into the process by means of a spray device operated by hand or by a pump of some sort. The Grizzly catalog has several different options for adding coolant capability to your grinder.

SECTION 6: MAINTENANCE
Make a habit of inspecting your Surface Grinder each time you use it. Check for the following con­ditions and repair or replace when necessary:
1. Loose mounting bolts.
2. Worn switch.
3. Worn or damaged cords and plugs.
4. Damaged Grinding Wheel.
5. Any other condition that could hamper the safe operation of this machine.
General
Grinding Wheels
The grinding wheel should be inspected before every use. Use the ring check method noted in the Grinding Wheel section in Operations to veri­fy the structural integrity. If using coolant during grinding, always run the wheel for 5-10 minutes at the end of the operation to remove any coolant from the wheel. Take care in storing grinding wheels to keep them free from potential damage by being dropped, or having other items drop on them.
Table
The table and other non-painted surfaces on the Model G5963 should be protected against rust and pitting. Wiping the table surface with a slight­ly oily rag will protect bare metal surfaces from moisture.
Periodically lift the sliding table off of the ways and make sure the V-grooves and the helical gear underneath are free of debris and metal dust. Wipe the V-grooves of the table and the saddle down with way oil (Mobil Vactra #2 or equivalent) prior to reassembly.
Lubrication
Besides the one-shot lubrication system, the Model G5963 features factory-sealed bearings. A sealed bearing requires no lubrication during its lifetime. Should a bearing fail, your surface grinder will probably develop a noticeable rumble, which will increase when the machine is put under load. If allowed to get worse, overheating of the journal containing the bad bearing could occur. If the bad bearing is not replaced, it will eventually seize - possibly doing damage to other parts of the machine. Bearings are standard sizes and can be replaced through Grizzly.
