What are the main functions of a shot blasting machine?

The main functions of a shot blasting machine are as follows:
Remove the oxide scale and residue on the surface of the casting to improve its corrosion resistance and wear resistance.
Shot blasting treatment on the surface of heat-treated steel can eliminate internal stress and improve the yield strength and fatigue strength of the steel.
Shot blasting treatment of welded structural components can remove welding slag, spatter, and eliminate stress concentration inside the components during the welding process.
Shot blasting treatment of rust, burrs, and scratches on metal surfaces can remove dirt and improve the wear resistance and surface roughness of workpieces.
Forming a compressive stress layer on the metal surface improves the strength, fatigue life, and wear resistance of the material.
Remove scratches and burrs from the metal surface to make it smoother and even.
