Shot blasting is a process that uses a high-speed rotating impeller to throw abrasives out to impact the workpiece at high speed to clean the surface; or to distort and deform the crystal lattice on the surface of the workpiece through high-speed impact to increase the surface hardness and strengthen the surface.
Before performing shot blasting treatment, comprehensively check the overall condition of the shot blasting machine, and select reasonable current, projection angle, shot blasting speed, etc. according to different models of shot blasting machine. The quality of the abrasive has a great influence on the quality of the workpiece surface treatment. For example, the hardness, particle size, and metallographic structure of the abrasive will all affect the shot blasting effect.
