ABSTRACT:
Method of grinding a concentrically clamped crankshaft, a crankshaft grinding machine for carrying out the method, and a crankshaft of high-alloy steel or cast material. The method provides for pin journals and main journals of the crankshaft to be ground in one set-up such that first, at least the main journals are rough-ground and then the pin journals are finish-ground and after that the main journals are finish-ground. The crankshaft grinding machine forms a machining center by means of which corresponding rough-grinding and finish-grinding is possible in a single set-up.
