Method and device for post-processing a crankshaft

A method for the post-processing of a crankshaft for the purposes of correcting concentricity errors and/or for the purposes of length correction, the method comprising the following steps:

• determining concentricity errors for sectors of the crankshaft and/or determining a length deviation from a setpoint length for at least one portion of the crankshaft;
• introducing an impact force for correcting the concentricity errors and/or the length deviation into at least one defined transition radius between connecting-rod bearing journals and crank webs and/or between main bearing journals and the crank webs of the crankshaft by means of at least one impact tool;
• and
• hardening the transition radii of the crankshaft prior to the determination of the concentricity errors and/or the determination of the length deviation, wherein the portion of the crankshaft in which the length deviation from the setpoint length is determined corresponds to a partial length of the crankshaft.
