Shot peening equipment

 

 

 

Shot peening equipment is used to cold - work metal parts to harden their surfaces and remove residual stresses. It applies compressive stresses to the peened surface to increase fatigue strength and resistance to stress - corrosion cracking. It can also be used to improve oil - retention properties, such as on gear teeth.

The working process of shot peening equipment is similar to that of shot blast machines. Metal shots or glass beads are propelled at high speed to impact the surface of the workpiece. The difference is that the purpose of shot peening is mainly to improve the mechanical properties of the material surface rather than just for cleaning.

There are strict requirements for the shot size, intensity, and coverage in the shot peening process. For example, the shot size is the nominal diameter of the shot in inches, and the intensity is represented by the arc height value of the Almen test strip after peening. Different applications and materials require different parameter settings to achieve the best peening effect. Shot peening equipment is widely used in the aerospace, automotive, and mechanical manufacturing industries to improve the performance and service life of key components.
