A grinding wheel is a key abrasive tool. It is used for grinding, cutting and polishing metals, stone and ceramics.It is widely used in mechanical manufacturing and tool maintenance.

Cut off power immediately and evacuate operators. Remove broken wheel scraps, check guard and spindle fault. Discard damaged wheel entirely and install new qualified one, test run before reuse.

Dry grinding wheels with large pores cool by air for rough grinding of steel and cast iron. Dense wet grinding wheels work with coolant to get smooth surface for precision machining of stainless steel.

Inspect new wheels for cracks via tapping check and speed marking first. Fit intact pads and matched flanges, align bore properly, avoid over-tightening nuts and run idle before grinding.

Grinding wheels work well on hard materials like steel, iron, copper, stone, glass and ceramics. Different wheels are chosen for different workpieces. They are not fit for soft materials such as rubber.

Grinding wheels are mainly classified by abrasive material, shape and grain size. Different types include alumina and silicon carbide wheels. They also vary in form and coarseness to fit different tasks.
