Abstract

The method involves fixing a support system (23) of an acoustic assembly (3) at a rotating machine or in a common recess to be processed, without complete disassembling of a rotor (R) of the machine, where the system has a hinge (28) permitting the rotation of the acoustic assembly around an rotation axis coinciding with an rotational axis (X) of the rotor of the machine. A region of the machine is shot blasted using projectiles set in movement by the acoustic assembly. The acoustic assembly is displaced in rotation on 360 degree around the rotational axis of the rotor. An independent claim is also included for a shot blasting system for processing a rotating machine comprising a rotor.
