Abstract
A finishing device for finish machining of a workpiece, in particular of a crankshaft or a camshaft, comprising a workpiece holder and a rotary drive for rotating the workpiece about the workpiece axis thereof, comprising at least one first finishing tool for machining a main bearing concentric to the workpiece axis and at least one second finishing tool for machining an additional bearing, wherein the finishing tools can be moved along a transport axis which extends via a working area defined by the workpiece holder so that the finishing tools can be moved into an additional area arranged outside the working area.
Claims15
A finishing device for finish machining a workpiece, the device comprising:
- a first workpiece holder;
- a rotary drive configured to rotate the workpiece about a workpiece axis;
- a first finishing tool configured to machine a main bearing concentric to the workpiece axis;
- a second finishing tool configured to machine an additional bearing;
- a second workpiece holder arranged in an additional area outside a working area, the additional area being a portion of an interior of the finishing device that is adjacent to the working area in a direction of a transport axis,
- wherein the finishing tools can be moved along the transport axis which extends via the working area defined by the first workpiece holder so that the finishing tools can be moved into the additional area.
A method for operating a finishing device for finish machining a workpiece, the method comprising:
- providing a first workpiece holder;
- providing a rotary drive configured to rotate the workpiece about a workpiece axis;
- providing a first finishing tool configured to machine a main bearing concentric to the workpiece axis;
- providing a second finishing tool configured to machine an additional bearing;
- providing a second workpiece holder arranged in an additional area outside a working area, the additional area being a portion of an interior of the finishing device that is adjacent to the working area in a direction of a transport axis;
- wherein the finishing tools can be moved along a the transport axis which extends via the working area defined by the first workpiece holder so that the finishing tools can be moved into the additional area;
- moving the finishing tools into the additional area;
- aligning the finishing tools in the additional area, optionally using a setup workpiece;
- subsequently,
- moving the finishing tools in their aligned state into the working area and are used there for finish machining a workpiece.
