The wheel is the main abrasive grinding. The wheel is in the added binding agents, a porous body made by the green compacts, grinding disc and firing the abrasive. Abrasive, bond and manufacturing processes, grinding wheel characteristics vary widely, so grinding machining quality, productivity and economy. The characteristics of the grinding wheel is mainly determined by the abrasive strength, binding agents, hardness, organization, shape, and size and other factors.

The abrasive is the major component of the wheel, it has a high hardness, wear resistance, heat resistance and a certain degree of toughness to withstand the grinding cutting heat and the cutting wheel, and should also have sharp angles in order to facilitate grinding metal.
