Can be divided into the ordinary abrasive (corundum and silicon carbide) Wheel and natural abrasive superhard abrasive (diamond and cubic boron nitride) grinding wheels with abrasive;

       Shape can be divided into level grinding wheel, bevel grinding wheel, cylindrical grinding wheel, cup wheel, cutting wheel; binder can be divided into ceramic grinding wheel, resin grinding wheel, rubber wheel, metal grinding wheel. The characteristic parameter of the wheel main abrasive, viscosity, hardness, binding agent, shape, size and so on.

       Due to the grinding wheel usually work at high speed, and thus should be carried out before use rotation test (to ensure that the wheel at the highest speed, not broken) and static balance test (to prevent work caused by machine vibration). Grinding wheel after working for a period of time should be trimmed in order to restore the grinding performance and correct geometry.
