Grinding wheel introduction

Grinding wheel is a circular fixed abrasive tool, which is made of abrasive and binder. The characteristic of the grinding wheel is determined by the factors such as abrasive, grain size, hardness, bond, shape, size and so on. A wide variety of grinding wheel, according to the abrasive can be divided into ordinary abrasive (corundum and silicon carbide, etc.) grinding wheel and natural abrasive super hard abrasive and (diamond and cubic boron nitride, etc.) grinding wheel; Shape can be divided according to flat shaped wheel, bevel wheel, wheel cylinder, cup wheel, disc wheel, etc., and according to the bond can be divided into ceramic grinding wheel, resin grinding wheel, rubber wheel, grinding wheel, metal.

The characteristic parameters of the grinding wheel mainly include abrasive, grain size, hardness, bond, shape, size and so on. Since the grinding wheel usually work at high speed, it should be carried out before the use of rotary test (to ensure that the grinding wheel at the maximum operating speed, not broken) and static balance test (to prevent the work caused by machine vibration). After working for a period of time, the grinding wheel should be trimmed to restore the grinding performance and the correct geometry.
