Abstract

The method involves using fast-running, driven cam on which slow running sockets with tools are rotatably located. A combination of at least two counter-balanced tool sockets (3) on only one eccentric shaft (7), either automatically rotate in a striking fashion or do so in a driven manner. Counterweights (5) are provided on the eccentric shafts on which the sockets and tools are balanced. At least two sockets and tools are arranged on an eccentric shaft and are balanced against one another by at least two cams. A central bearing with a drive is provided for each cam with a tool socket. <IMAGE>
