Grinding Wheels

 

 

 

 

 

 

Always be aware of the condition of your machine. Routinely check the condition of the following items and repair or replace as necessary:

•Damaged or loose grinding wheels.

•Loose mounting bolts or arbor nuts.

•Worn switch.

•Worn or damaged cord.

•Worn or damaged support bearings.

•Any other condition that could hamper the safe operation of this machine.

Lubrication

Sealed and pre-lubricated ball bearings require no additional attention for the life of the bearings. All bearings are standard sizes, and replacements can be pur- chased from our Parts Department or a bearing supply store.

The grinding wheel should be visually inspected before every use. Take care when storing grinding wheels to keep them free from potential damage due to being dropped or having other items dropped on them. Store all grinding wheels in a dry location. Type 1 grinding wheels should be stored vertically with cushioning mate- rial between each wheel.

If a grinding wheel diameter has been reduced to 21⁄2", the wheel must be replaced. Operating a wheel at anything less than this diameter can lead to wheel explosion and serious personal injury.

Grinding wheels will require periodic dressing. Refer to the Wheel Dressing instructions on Page 13 for details on how this is done.

Buffing Wheels

Buffing wheels should be regularly cleaned of compounds to maintain their effectiveness and surface texture. Wool buffing wheels will shed fibers and will need to be replaced eventually. If a buff- ing wheel is reduced to 21⁄2", the wheel must be replaced. Operating a wheel at anything less than this diameter can tear or rip, posing an entangement hazard for the workpiece and operator.
