Classification of grinding wheels

There are many types of grinding wheels. According to the abrasive used, it can be divided into ordinary abrasive (corundum and silicon carbide) grinding wheel and natural abrasive super-hard abrasive and (diamond and cubic boron nitride) grinding wheel; according to the shape, it can be divided into flat grinding wheel, oblique side grinding wheel, cylindrical grinding wheel, Cup-shaped grinding wheel, dish-shaped grinding wheel, etc.; according to the bonding agent can be divided into ceramic grinding wheel, resin grinding wheel, rubber grinding wheel, metal grinding wheel and the like. The characteristic parameters of the grinding wheel mainly include abrasive, particle size, hardness, binder, shape and size. Since the grinding wheel usually works at high speed, the rotation test should be carried out before use (to ensure that the grinding wheel does not break at the working speed) and the static balance test (to prevent the machine from vibrating during work). After the grinding wheel has been in operation for a period of time, it should be trimmed to restore the grinding performance and the correct geometry.
