A punching machine has a tool (6) holder (7) which rises, falls and rotates about the lift/lower axis (8) under a spindle (20, 21) power (5) control unit (32). Each spindle is driven by a discrete motor (23, 24), the action being coordinated by the control unit (32). The tool drive elements (14, 15) are linked when moving about the spindle axis of rotation (22). |
