Abstract: In a method for producing workpieces having inner and/or outer contours deviating from a circular shape, at least one workpiece is clamped on a machine and the workpiece is driven in rotation about a rotational axis of the workpiece at a first constant velocity. At least one tool is arranged on a carriage that is moveable radially to the rotational axis of the workpiece as well as axially in the longitudinal direction of the rotational axis of the workpiece. The tool is rotatably driven about a rotational axis of the tool that deviates from the rotational axis of the workpiece such that an active cutting surface of the tool moves on a circular path at a second constant velocity. The second constant velocity is selected such that its revolutions per minute deviate from the revolutions per minute of the first constant velocity with respect to size and/or rotational direction.

Abstract: A device for eccentrically moving and positioning a tool, workpiece, or measuring instrument in connection with machining or measuring operations where a large outer drum is rotatably arranged inside a headstock and carries in an eccentrically offset parallel bore a smaller inner drum which, in turn, carries a likewise eccentrically offset parallel spindle sleeve and work spindle which are movable axially in relation to the headstock. Each drum and the work spindle have a drive unit and a clamping device, the drive units of the drum including a main drive and a positioning drive.
