Shot peening utilizes a technique to improve the surface durability of metals. It involves striking the workpiece with small, hard media at high velocity. This process creates a compressive stress layer on the surface, which effectively enhances its resistance to fatigue crack initiation. Shot peening can boost the fatigue life of metal components

Shot peening machines are widely applied in various industries for enhancing the performance of metallic components. The process involves striking tiny metal or ceramic shots onto the surface of a workpiece at high speed. This impact creates compressive stresses on the material's surface, which in turn strengthens its fatigue resistance, wear resi
