Abstract
A machine tool head comprises a fork fitted to a support having a plurality of degrees of freedom, and a tool unit hinged to the fork. The tool unit contains equipment designed to control a tool carrier so that it can traverse along an axis, and equipment designed to perform controlled tool rotation around that axis. The tool carrier is in the form of a shaft which is mounted on a bushing to which a crown gear is connected. The crown gear engages a first pinion which meshes with a second pinion that is connected to a gear motor. The gear motor and the first and second pinions are mounted as a unit on a hinge to the structure which supports the bushing and a biasing mechanism is provided for urgening the first pinion into meshing engagement with the crown gear.
