摘要

A tool holder is mounted upon the crossfeed arrangement of a machine tool, e.g. a lathe, and have a swing part which is rotatable about one axis, a cutter head which is rotatable relative to the swing part about a second axis perpendicular to the first axis, the first axis being orthogonal to a plane of displacement of said crossfeed arrangement. Means is provided for the programmed positioning of the head relative to the swing part and the swing part relative to the crossfeed arrangement so that the angular positions of the cutter can be effected under programming control within wide range of angular orientations and receiving outside the X-Z plane is possible.
