Abstract: The invention relates to a process for finish-machining of the bearing positions (11) on main bearing journals and connecting rod bearing journals of crankshafts (1) for motor car engines, whereby the crankshafts (1) have roundings (14) between the bearing positions and the transitions (7) adjacent in each case to the bearing positions (11). The roundings (14) are deep rolled with a deep rolling tool and then, maintaining a distance interval (17) to the individual transition (7) in each case the bearing position (11) concerned is machined with removal of material with a small cutting depth (18, 20).
