Abstract
The present invention concerns a method of finishing machining rotary parts which are at least partially subjected to a hardening process until they are in a condition of being ready for use. The rotary parts may be crankshafts, or bearing surfaces of crankshafts, in particular automobile crankshafts. The object of the invention is to simplify the removal of material when machining bearing locations of a crankshaft which is to be hardened. After the original shaping operation, removal of material is effected at most by cutting machining with a given cutting edge.
