method for ultrasonic kugelstahlen of grossformatigen annular surfaces of thin-walled workpieces

摘要

The invention concerns a method for ultrasonic shot blasting of large-dimensioned annular surfaces (5) on thin workpieces (1). Said method is characterised in that the surface to be shot blasted (5) performs at least N = five revolutions in front of the shot blaster opening (10) during the shot blasting process, so as to reduce the deformations of the workpiece (1).
