Abstract

The invention relates to a method for machining surfaces of the bearing seats of main and pin bearings on crankshafts made of cast steel following the machining of surfaces with an undefined cutting edge by grinding or finishing. The problem of improving the quality of the running surfaces of the bearings of hardened or unhardened crankshafts is solved. This is achieved by irradiating the surfaces with a laser beam.
