ABSTRACT:
An apparatus for the out-of-round circumferential machining of workpieces includes a tool holder, a tool bit carried by the tool holder and a motor having a rotor operatively coupled to the tool holder for a radial feed of the tool bit. The motor can be numerically and electronically controlled dependent upon a desired out-of-round contour of the workpieces. The moment of inertia of the tool holder, the tool bit and any other component moving with the tool holder as a unit during feed motion is at the most equal to the moment of inertia of the rotor.
