(1) Since the abrasive wheel itself has high hardness and heat resistance, therefore grinding tool can process high hardness materials, such as hardened steel, carbide, etc.
(2) Grinding wheel and grinding characteristics determine the grinding process can make a uniform system of micro cutting, general ap = 0.001 ~ 0.005mm; high grinding speed, generally up to v = 30 ~ 50m / s; Grinding machine rigidity; With hydraulic drive, so that grinding can economically achieve high machining accuracy (IT6~IT5) and small surface roughness (Ra=0.8~0.2 μ m). Grinding is one of the main methods of finishing parts.
(3) Due to the dramatic friction, grinding temperature is very high.This can cause stress and deformation of the workpiece, even resulting in burns on the surface of the workpiece. It is necessary to inject a large number of grinding coolant to reduce the grinding temperature. Coolant may also play a role of chip and lubrication.
