Shot Peening Machine Manufacturer in India

Working Principle of Shot Peening Machine

Shot Peening Machines are designed to improve the fatigue strength, durability, and performance of metal components by bombarding their surfaces with controlled high-velocity steel shots. Unlike conventional shot blasting, shot peening is a cold working process that intentionally induces compressive residual stress on the surface without removing material.

The machine accelerates steel shots using high-speed centrifugal blast wheels or compressed air nozzles, directing them precisely onto the workpiece. Each impact creates a small indentation, producing a uniform compressive stress layer that significantly enhances resistance to fatigue failure, stress corrosion cracking, and wear.

Shot Peening Machines are widely used in the automotive, aerospace, railway, spring manufacturing, defence, heavy engineering, and industrial equipment industries to strengthen gears, crankshafts, connecting rods, coil springs, turbine blades, aircraft components, and other critical parts requiring extended service life.
