Grinding wheel wear is generally composed of abrasive grains held together by a bond structure which contain some amount of porosity. The grinding wheel typically operates at high rotational speeds. The wheel speed depends several factors, some of which included the grindability of the wheel, the shape of the part, and the material of the workpiece. These properties will affect important parameters such as the surface finish, surface integrity, and wheel wear. Likewise, the grinding wheel speed will depend on which abrasive process is needed and which finishing process is desired. A worn grinding wheel can be dressed to restore its grinding properties.
