Abstract
A device for finish-machining a workpiece in the form of a crankshaft or a camshaft includes a workpiece holder and a rotational drive configured to rotate the workpiece about a workpiece axis. A first finishing tool is configured to machine a main bearing which is concentric with the workpiece axis. A second finishing tool is configured to machine an additional bearing which is radially offset from the workpiece axis. A first tool drive is configured to generate an oscillating movement of the first finishing tool in a direction parallel to the workpiece axis. A second tool drive is configured to generate an oscillating movement of the second finishing tool which is independent of the movement of the first finishing tool in a direction parallel to the workpiece axis.
