Zusammenfassung:The invention relates to a technical solution for the fine-machining of pre-machined bearing seats of the main bearings and crank pin bearings of crankshafts, the cutting tools being guided over different regions of the bearing surface of the respective bearing. The aim of the invention is to devise a technical solution which allows different surface geometries to be produced on the main bearings and on the crank pin bearings while producing precise workpiece surfaces on preferably unhardened crankshafts with high dimensional accuracy and surface quality and in an environmentally friendly manner by dry machining. This aim is achieved by a specific order of method steps and a device for carrying out said method.
