Shot Peening Explained: Process, Benefits & Applications

Shot peening is a cold working process to induce compressive stress on the surface of a material with sphere shots of steel, ceramic or glass media pneumatically propelled at relatively high velocities. These shot particles create a series of overlapping dimples on the material's surface which put the upper layers of the material into compression, and help to prevent fatigue failure in the material.

CNC SHOT PEENING MACHINE

MEC CNC Peening Machine

MEC CNC peening machine is designed for effective peening on components used in Aerospace, Aero engine components, Oil & gas, Gas turbine, Automotive, etc applications and is compliant with SAE AMS-2432, MIL-S-13165 standard & all major OEM computerized peening specifications. To generate the controlled compressive stress to the surface and to enhance the surface properties, increase fatigue strength by creating small pores, increase life of components and prevent galling, fretting, cracking & corrosion
