Abstract
A description is given of an apparatus and a method for grinding a workpiece, in particular a shaft part. According to the method, the workpiece is clamped in place for the grinding working and its geometry is subsequently ground in such a way as to maintain its dimensions and shape. According to the invention, at least part of the surface of the workpiece is precision-worked at least partly at the same time as the grinding. The apparatus according to the invention has a work-spindle headstock and a tailstock for clamping the workpiece in place as well as a grinding unit with a grinding wheel for grinding the workpiece. The grinding unit and workpiece are arranged movably in relation to each other in a controlled manner. The apparatus according to the invention additionally has a precision-working unit, which can be moved according to the geometry of the workpiece in such a way that at least part of the surface of the workpiece is able to undergo precision working.
