Abstract

The punch (10) advances to cut the wall of the workpiece (8), and returns to free the rotating cutting edge (22) of the tool (2). The movement is superimposed by an oscillating motion, and/or the high pressure engaging on the wall of the workpiece is applied by the pressure medium (D) in the same rhythm as the vibrations. Punching takes place during non/oscillating de/increasing high pressure of the medium.
