Abstract
The device comprises a shock wave generator (1, 2, 3) of the ballistic type comprising a projectile (1) provided to execute a to and fro movement within a guide tube, under the control of pneumatic means (13, 14, 5) disposed at one end of this guide tube. A waveguide (4, 19) exhibits an entrance interface (9) situated at the other end of the guide tube (2) and provided to be struck periodically by the projectile and thus to generate, by ballistic effect, ultrasonic shock waves. This waveguide per se is formed by a metal rod, one end of which forms the abovementioned entrance interface and can oscillate longitudinally within a guide (12), while its other end is provided to act by impact on the object (21) to be destroyed or to be processed.
