Machine tool for bevelling of tooth flanks of a gear

The invention relates to a machine for machining by cutting with workholder and tool holder rotating in positive drive with respect to each other, the axis (z) of which toolholder extending askew to the workholder axis of rotation (x), is swingable and lockable about an axis (y) which intersects the axis of rotation (x) of the workpiece and the axis (z) of the toolholder at right angles, the toolholder being displaceable in the direction of the axis of rotation (x) of the workholder and the axis of swing (y) of the toolholder. In order to be able to carry out other cutting methods of machining in addition to a milling of a workpiece, the invention proposes providign individual electric drives (6, 7) for workholder (2) and toolholder (5), which drives are connected by an electronic positive drive device (13) and can individually be disconnected from it, the toolholder (5) on its part being seated on a tool slide (16) which is displaceable along the axis of the toolholder and on which there is also arranged a supplementary toolholder (18) which can be brought into working position by relative movement with respect to the tool slide (16).
