Abstract

The invention relates to a method for post-processing a crankshaft (4), in particular in order to correct concentricity errors and/or for a length correction. Sectors (S1,S2,S3,S4,S5,S6) of the crankshaft (4) which produce and/or characterize concentricity errors are detected and/or a length deviation (ΔL1 ΔL2, ΔL3) from a target length (L1,L2, L3) is determined for at least one section of the crankshaft (4). An impact force (Fs) is then introduced into at least one defined transition radius (8) between connecting rod bearing journals (5) and crank webs (7) and/or between main bearing journals (6) and the crank webs (7) of the crankshaft (4) by means of at least one impact tool (16) in order to correct the concentricity errors and/or the length deviation (ΔL1 ΔL2, ΔL3).
