Abstract
A tool grinding machine has a machine control unit, which by means of a suitable measuring device, which for instance comprises a tracer (9) and a measuring module, first determines the wobble runout with respect to the ideal receptacle axis (C) of a workpiece receptacle. In the grinding machining of the blank (7) or a workpiece, this wobble runout is taken into account and compensated for; that is, the grinding tools are made to trace a tumbling workpiece in such a way that the workpiece is machined to the exact intended dimensions and concentrically.
