| Type | Code | Performance | Function |
| Ceramics | V | Good heat resistance and corrosion resistance, high porosity, bad flexibility and the profile can be maintained well | Widely used, suitable for the profile grinding (v<35m/s), wheel gear grinding, thread grinding and so on. |
| Resin | B | Good intensity and flexibility, impact resistance, bad sturdiness and heat resistance, low porosity | Suitable for the high-speed grinding (v>50m/s), can be made sheet wheel for mill groove, incision and so on. |
| Rubber | R | Better intensity and flexibility, bad heat resistance, low porosity, caduceus grains | Suitable for the grinding wheel and guide wheel for centerless grinding; as well as sheet wheel and polishing wheel for mill groove, incision and so on |
The grinding wheel is one of the most main grinding tool in abrasive machining. The characteristics parameters of the grinding wheel mainly include abrasive, granularity, hardness, binding agent, shape, size, etc. Due to the grinding wheel is usually work under high speed, and thus it should be tested by turning test before using (to guarantee the grinding wheel not to burst as working at the highest speed) and static balance test (to prevent machine tool from vibration while working). After a period of time, the grinding wheel should be repaired and maintained to recover the grinding performance and the correct geometrical shape.
