Vor- und Fertigschleifen einer Kurbelwelle in einer Aufspannung

摘要

The present invention relates to a method for grinding a centrally clamped crankshaft (1). The invention also relates to a grinding machine (43) for crankshafts for carrying out said method and a crankshaft (1) consisting of high-alloy steel or cast. According to the inventive method, lifting bearings (12) and main bearings (11) of the crankshaft (1) are ground in a clamping in such a way that at least the main bearings (11) are rough-ground and subsequently the lifting bearings (12) and then the main bearings (11) are finish-ground. The grinding machine (43) for crankshafts forms a working centre by means of which corresponding rough-grinding and finish-grinding are possible in one single clamping.
