Abstract
A machine for simultaneously milling several grooves in rotating workpieces by means of a rotating one-toothed milling tool, whereby the rotational speeds of the milling tool and workpiece stand in a ratio determined by the number of grooves, and whereby the milling tool in the longitudinal direction from the free end of the workpiece--freely-cutting--is plunged in the workpiece which is advanced in the longitudinal movement. The tool carrier is pivotable about an axis lying perpendicularly to the rotational axis of the workpiece such that the rotational plane of the cutter tool is able to be brought in an acute angle relative to the rotational axis of the workpiece.
