So why does this happen? One reason is that abrasives are built to work within a specific range of RPM's, which are usually outlined on the packaging or on the wheel itself. If your wheel exceeds these RPM's or is otherwise used improperly, it can tear apart. Another reason is that some wheels just aren't built to last.
Step 1 Unplug the bench grinder. Secure a lockout tag over the grinder switch set. Step 2 Push the locking button to keep the grinder motor from spinning. Turn the nut holding the grinding wheel to the grinder counterclockwise with an adjustable wrench. Spin the nut off the spindle. Pull the old grinding wheel off the grinder. Step 3
Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.
Grinding wheels on floor stands, pedestals, benches, and special-purpose grinding machines and abrasive cutting-off wheels shall have not less than the minimum exhaust volumes shown in Table D-57.1 with a recommended minimum duct velocity of 4,500 feet per minute in the branch and 3,500 feet per minute in the main.
2.The grinding wheels should be stored on a straw mattress or a soft surface for their safety. Arrange the wheels column wise if there is a large quantity of wheels. Keep the small grinding wheels on the top shelves while keeping the heavier ones on the bottom. The height should not be an issue while arranging the wheels on the bottom shelf.
