Abstract (en)

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).

Abstract (fr)

L'invention propose un procédé de grenaillage dit "par ultrasons" pour grenailler des surfaces (5) annulaires de grandes dimensions sur des pièces (1) minces. Un tel procédé est remarquable en ce que la surface à grenailler (5) effectue au moins N = cinq révolutions devant l'ouverture (13) de l'enceinte de grenaillage (10) pendant le grenaillage, afin de réduire les déformations de la pièce (1). <IMAGE>
