Working principle and application of shot blasting machine

Shot blasting machine is a machine tool that uses projectiles to strengthen the surface of workpieces, and is an important equipment widely used in industrial sectors such as mechanical manufacturing, automobiles, and tractors. It is widely used in industries such as shipbuilding, bridge construction, and steel structure manufacturing, playing an important role in rust removal and strengthening treatment of metal structural components. The shot blasting cleaning process uses the friction between the high-speed shot ejected by the shot blasting machine and the workpiece to remove the rust layer and its dirt on the surface of the workpiece. Due to the impact and cutting of the projectile, as well as the grinding effect of the abrasive, a layer of oxide skin with high hardness and a certain thickness is formed on the inner and outer surfaces of the workpiece; At the same time, due to the high temperature, the iron material undergoes plastic deformation, which improves the plasticity of the material.
