Abstract (en)
[origin: EP2769806A1] The device (10) has a workpiece holder (16) and a rotational drive (22) for rotating a workpiece around its workpiece axis (24). A first finishing tool (56) is provided for machining a main bearing (34), which is concentric to the workpiece axis, and a second finishing tool (58) is provided for machining an additional bearing (36), which is offset relative to the workpiece axis in a radial direction. A tool drive (48) is provided to generate an oscillating movement excluding the finishing tools in a direction parallel to the workpiece axis. An independent claim is included for a system for finish-machining of a workpiece in the form of a crankshaft or a camshaft.
