Shot peening machine USF Surface Preparation Group

Shot peening is a specialized blasting process that bombards a metallic work piece with a round abrasive, typically steel shot, glass beads, or ceramic shot, thereby compressing the surface. This compression can greatly improve the strength and fatigue life of the part. An analogy would be the blacksmith that hammers a sword to increase its strength.

Parts that are commonly shot peened include:

- Valve Springs
- Suspension Springs
- Leaf Springs
- Torsion Bars
- Gears
- Connecting Rods

There are many others. Shot peening has the potential to improve the service life of nearly any metallic work piece that is subject to repeated stresses.
