METHOD FOR FINISHING CRANKSHAFTS FOR MOTOR VEHICLE ENGINES

摘要

The crankshafts have rounded areas (14) between the bearing points and the transitions (7) adjoining same which are then roller-burnished with a roller-burnishing tool. Whilst keeping a distance (17) from the relevant transition the bearing point (11) is then machined with a shallow cutting depth (18, 20). The rolling depth when roller burnishing the rounded areas (14) is preferably 0.2 mm and the cutting depth is preferably 0.25 mm. Independent claim describes crankshaft (1) which has touching radii (15) between the transitions and the relevant bearing points.
