Abstract
A machining unit having a rotary head that bears pivoting tools for machining a non-rotating part centered on a rotational axis of the head. The supports for the pivoting tools are mounted in the head to pivot about respective axes that are parallel to the rotational axis. Each support has a transversely arranged control lever. A control bushing is mounted coaxially on the machining unit and is arranged to slide axially and adopt a first, advanced position or a second, retracted position. At one end of the control bushing bearing is arranged an ellipsoidal control surface so as to cooperate with helical directing surfaces that are connected to the tools in order to execute a plunging movement of the tools. There is provided a phase-offset device, which is arranged to move the control bushing into two, three or four different predetermined angular positions around its axis.
