Verfahren zur spanenden Bearbeitung rotationssymmetrischer Werkstückflächen, insbesondere von Kurbelwellen, sowie Werkzeug zur Durchführung eines solchen Verfahrens

摘要

The rotationally symmetric workpiece surface (9) rotates during the machining and is first of all rough-machined and then finish-machined by means of a cutting tip (8). During this finish machining, the workpiece surface (9) is machined by a divided cutting-edge arrangement (22 to 28) of the cutting tip (8) by the longitudinal turning process. The tool (1) is fed in radially to the workpiece surface (9) during the finish machining and is moved in the axial direction of the workpiece surface (9) for the longitudinal turning by means of the cutting tip (8). The cutting tip (8) has at least two cutting edges (22 to 28) which lie axially next to one another at a distance apart and with which the finish machining is effected. The finish machining by longitudinal turning has the advantage that the cutting edges (22 to 28) do not change their position relative to the workpiece surface (9) during the finish machining and can be arranged in such a way that only slight forces result. The cutting edges are subjected to only slight wear, and the corresponding workpiece is only slightly deflected. A tendency to chatter during the finish machining is thereby avoided and a high machining accuracy is achieved.
