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.

Before use, check if the wheel is intact. Wear protective goggles and gloves while operating. Do not stand directly in front of the rotating wheel. Avoid excessive force during grinding.

Grinding wheels are mainly used for grinding, polishing and cutting workpieces. They can remove burrs and trim materials. They also serve to sharpen various tools, and are widely used in mechanical processing.
