Types of peening machine

There are 2 types by different abrasive acceleration system.

Centrifugal (impeller) type
Pneumatic type
Pros & Cons
Centrifugal (impeller) type
  • Large processing area
  • Large shot projection volume
  • Less limitation of work shape
  • Adequate for batch treatment
  • Low intensity
  • Not good for spot peening
Pneumatic type
  • High intensity (good for spot peening)
  • Projection conditions (volume/angle) can be adjusted
  • Easy condition control
  • Small processing area
  • Not adequate for mass treatment
