Method and device for processing a hard-coated workpiece surface of a rotationally symmetrical workpiece

A device for processing a hard-coated and planar workpiece surface of a rotationally disk-shaped symmetrical workpiece (1), comprising:

• a workpiece driving device (3) for generating a rotational motion around a workpiece axis of rotation (1.1),
• at least one grinding wheel driving device (4a, 4b) for generating a rotational motion around at least one grinding wheel axis of rotation (2a.1, 2b.1) of at least one grinding wheel (2a, 2b),
• at least one infeed device (5) for bringing the at least one grinding wheel (2a, 2b) into contact with the workpiece surface, and
• at least one angulating device (6a, 6b) for angulating the at least one grinding wheel axis of rotation (2a.1, 2b.1) and the workpiece axis of rotation (1.1) to each other, so that the at least one grinding wheel axis of rotation (2a.1, 2b.1) and the workpiece axis of rotation (1.1) are not parallel, and
• a controller configured to change an angle of incidence between the grinding wheel axis of rotation (2a.1) and the workpiece axis of rotation (1.1) during a processing operation while the workpiece surface is in contact with the grinding wheel.
