Abstract
A machining unit for machining, in particular turning and/or milling, workpieces, in particular elongate workpieces, in particular shafts, includes a machining tool. The machining tool can be moved along at least two different, in particular combined, motion paths in a motion plane. The machining until also includes at least one drive unit, which is designed for moving the machining tool along a first motion path and along a second motion path, which is different from the first motion path, possibly in a combined manner.
Claims20
A machining unit for turning or milling an outer surface of a workpiece having a first axis defining a longitudinal axis of the workpiece in a machining device, comprising:
- a housing unit including an inner space, the housing unit (5) including a flange for coupling to a flange of a function unit, the housing unit and the function unit disposed within and moveable with respect to the machining device, the housing unit further being moveable with respect to the workpiece;
- a turning or milling tool, wherein the turning or milling tool can be moved in at least two different combined paths of movement in a horizontal machining plane, wherein the turning or milling tool is at least partly arranged or formed inside the inner space of the housing unit;
- and
- at least one drive unit, equipped for generating a combined movement of the turning or milling tool, in a first path of movement and in a second path of movement which is different from the first path of movement, wherein the at least one drive unit is arranged or formed at or in the housing unit of the machining unit;
- wherein the turning or milling tool is moveable independently of the housing unit to perform trochoidal or cycloid motions in the at least two different combined paths of movement in the horizontal plane independently of the housing unit;
- wherein the machining unit is moveable along a second axis parallel to the first while simultaneously moving in said trochoidal or cycloid motion with respect to the workpiece,
- wherein the turning or milling tool is rotatable about a third axis that is perpendicular to the second axis, and
- wherein the turning or milling tool is moveable unimpeded along the entire length of the workpiece in the second axis;
- and the workpiece is fixed against motion in the first axis;
- the machining unit further comprising a control unit configured to control the turning or milling tool to perform said trochoidal or cycloid motions in the at least two different combined paths of movement in the horizontal plane.
