ABSTRACT:
A process for successive grinding of crankpins of crankshaft by a grinder includes clamping the crankshaft at two spaced center journals thereof and rotating the crankshaft around the axis of a crankpin to be ground. To enable the maintenance of highly acurate production tolerances even for small quantities and large crankshafts in an economical manner, only crankpins directly adjacent to the center journals that are clamped are ground. Different clamping positions of the crankshaft are offset axially from one another by the center-to-center distance between two adjacent crankpins of the center journals or a multiple thereof.
