Wheelabrator NC Shot Peen Machine
Shot peening is a cold working process used to produce a compressive residual stress layer and modify the mechanical properties of metals. It entails impacting a surface with shot (round metallic, glass, or ceramic particles) with a force sufficient to create plastic deformation. Peening a surface spreads it plastically, causing changes in the mechanical properties of the surface.
The main benefit of shot peening is the delay or prevention of cracks in highly tensile stressed alloy components.
