Patent ID: 6926591

Claim:
A method of machining crankshaft-like workpieces with one machine, said method comprising the following steps: machining both concentric and eccentric rotationally symmetrical surfaces of the workpiece by means of material removing wherein the workpiece includes at least one side and rotationally symmetrical surfaces which are arranged both concentrically and eccentrically with respect to a central axis of the workpiece clamping the workpiece on a central axis and driving the workpiece rotationally in all machining steps on the central axis of the workpiece; machining the concentric rotationally symmetrical surfaces of the workpiece according to a desired cutting speed which is achieved primarily by the rotational speed of a workpiece; and machining when desired the eccentric rotationally symmetrical surfaces of the workpiece according to a cutting speed produced primarily by rotational movement of a tool; selectively driving the workpiece from only one end at high speeds of rotation if machined according to a desired cutting speed being achieved by a rotational speed of the workpiece and from the other end at low speeds of rotation and maintaining defined rotational positions of the workpiece around the axis of rotation of at least one spindle according to a cutting speed produced primarily by rotational movement of a tool.
