What is Shot Peening?
Process of shot peening involves accelerating a steel shot or other hard media (metal, ceramics, glass) toward a component’s metal surface at high velocities. The impact of the media with the metal surface causes a plastic deformation which changes the mechanical properties of the surface. The mechanical change of the metal surface produces compressive residual stresses and crack initiation is prevented or slowed down.
Used to induce residual compressive stress in the surface of components that are prone to cyclic and repetitive loads, the process also reduces stress corrosion cracking.
-Shot Peen Forming
This process compresses and extends the superficial layer of the component causing it to bow. Typical applications include the formation of skins, wing flaps, access panels, and sections of fuselage.
-Correction Of Distortion
(The reverse of shot peen forming) Shot peening is used to stretch and compress a localised area to achieve perfect flatness after a part has been distorted by heat or machining. Complex structural parts, ribs and spars typically undergo this process.
Shot Peening Media Used
Media used for the shot peening include: steel, ceramics and glass.
Ceramic Peening Services – Used to improve the wear properties of gears, ceramic and virgin media is used to blast the gear. The resulting dimples retain beneficial oils and eliminate geartooth pitting.
Metal Deburring Services – Our metal deburring services offer different types of media to remove burrs and other imperfections from the part.
Glass Bead Peening Services – Using glass beads, this process produces a clean, bright satin finish to the metal part.
Steel Shot Peening Services – Steel shot peening is used to deburr and clean metal parts while improving the fatigue life of the part.
Shot Peening Application
Our automated equipment is custom built to fit your requirements and application, from shot peening gears and turbine/jet engine blades to drills and engine blocks:
Shot peening machine for springs is used for shot peening various types of springs. Shot peening increases durability of springs, which are exposed to high alternative bending or torsion tensions. Shot peening of coil springs increase durability of coil springs under dynamic load. Shot peening machine has throwing wheels with frequency converters to set the outlet speed of abrasive. This indirectly provides adequate shot peening intensity of workpieces surface.
shot peening machine is designed for effective peening on Gears and Shaft. To generate the controlled compressive stress to the surface and to enhance the surface properties, increase fatigue strength by creatring small dimples which increase life of components. Shot peening is a cold working process in which the surface of the component being proceessed is bombarded with small spherical media. Each piece of shot striking the surface of the component acts as a minuscule peening hammer, deforming the component surface and causing a small indentation or dimple. The overlapping dimples develop a thin layer of metal in rsidual compressive stress at or near the surface. Since nearly all fatigue and stress corrosion failures start at the surfae of a part, the compressive stresses induced by shot peening can considerably increase component service life.
