1. A method for processing a hard-coated and planar workpiece surface of a rotationally disk-shaped symmetrical workpiece (1) with at least one grinding wheel, comprising the following steps:
driving the workpiece (1) into a rotational motion around a workpiece axis of rotation (1.1),
driving a grinding wheel (2a) into a rotational motion around a grinding wheel axis of rotation (2a.1),
angulating the grinding wheel axis of rotation (2a.1) and the workpiece axis of rotation (1.1) to each other so that the grinding wheel axis of rotation (2a.1) and the workpiece axis of rotation (1.1) are not parallel,
processing the workpiece surface with the grinding wheel (2a), wherein the grinding wheel (2a) is in contact with the workpiece surface,
wherein an angle of incidence between the grinding wheel axis of rotation (2a.1) and the workpiece axis of rotation (1.1) is changed during the processing step while the workpiece surface is in contact with the grinding wheel.
