The purpose is to prepare for the next step, that is, to ensure the roughness requirements of the next process, and also for the consistency of the surface, the shot peening has on the workpiece. For reinforcement, sand blasting is not obvious. Generally, shot peening is a small steel ball, and sand blasting is quartz sand. According to different requirements, the number of points.
