Method for finishing crankshafts for motor vehicle engines

摘要

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 ).
