Shot peening machine for springs

    Shot-Peening machine, stress peening are used in multi-industries, primarily in the automotive and aeronautical industry. The purpose of the machines is to harden the surface, durability of workpieces and thus exposed them to high alternative bending or torsion tensions for ensuring constant ALMEN parameters standard, to reduce the possibility of the occurrence of micro-fractures and extend the lifespan.

Main features Shot-Peening machine for Coil-Springs:

  • The Shot-Peening machines of coil springs increases the durability of coil springs under dynamic load.
  • Shot-Peening with a wide range of diameter and length of springs, by changing the pitches-interval and distance between rollers.
  • Shot peening of heavy-duty cylindrical coil springs by the newly developed coil spring pitches-pushing system.
  • Individual treatment of each coil spring. The coil springs rotate by rollers along with axial moving-forward through the blasting zone, so the peening is optimal for individual coil springs.
  • Adjustable shot peening parameters by the operation control panel (frequency inverter on shot-wheels projection, rollers’ drive, and pushing system through of VFD).
