ABSTRACT:
In a method and machine for balancing centering a workpiece, such as a crankshaft, to be machined only at certain portions and in which the workpiece is transversely displaced with respect to an axis of rotation so as to minimize any unbalance and is subsequently cut to length, after which centering bores are formed in the opposite end faces of the workpiece to define the axis of rotation, the final balancing after the finishing machining of the workpiece is optimized by pre-balancing the workpiece in a manner which takes into account only the unbalance of those workpiece portions which will not be machined to determine the extent and direction of the transverse displacement.
