Grinding particle thickness – 2 minutes to show you the key factors that affect the grinding effect and surface roughness

The size of grinding particles refers to the particle size of the grinding material, which directly affects the grinding efficiency and surface roughness. Grinding particles are usually made of different materials such as silica, alumina, silicon carbide, diamond, etc., and their fineness is usually expressed by the abrasive grain size. Common indicators of abrasive grain size include FEPA and JIS, etc.
