Drehmaschine und Verfahren zum Drehen eines Werkstücks auf einer Drehmaschine

摘要

A lathe includes a frame for supporting rotatable chucking equipment adapted to hold a work piece. The frame further supports at least one lathe tool for machining the work piece. The chucking equipment and the lathe tool are displaceable relative to each other in at least a radial direction. The lathe includes a housing attached to the frame, with the housing extending about a longitudinal axis and having a cylindrical inner space extending from one end of the housing. The inner space has a longitudinal axis parallel to, though offset from, the longitudinal axis of the housing. An angularly displaceable shaft is arranged in the inner space and carries the chucking equipment. A rotatable outer casing peripherally encloses the cylindrical elongate housing. The rotatable outer casing carries the lathe tool. Rotation of the rotatable outer casing causes the lathe tool to effect a radial displacement relative to the chucking equipment.
