3-PHASE CRANKSHAFT MACHINING |
摘要 |
The present invention relates to a method and an apparatus for the finish-machining of the bearing diameters, particularly the main bearing diameters and of the adjoining cheek side surfaces on crankshafts and similar workpieces in a single chucking. In order that this machining can be carried out rapidly and nevertheless with a high quality of production, the following method steps are carried out, one after the other: milling of the cheek side surfaces to nominal size up to the bearing diameter; turning of the bearing diameter down to a small oversize; turning-broaching of the bearing diameters to nominal size in order to obtain a good quality surface, and possibly turning/turning-broaching of recesses, clearance cuts and undercuts in the region of the bearings.
