Verfahren und Maschine zum Schleifen von Nockenwellen

摘要

The camshaft is clamped in a workpiece receiver and is rotated around its longitudinal axis while a grinding tool is moved in cutting contact with one or more cams 18a essentially radially to the cam rotational axis in the sense of generation of a desired cam shape. A grinding tool 19 with a grinding surface which is wider than, in particular at least twice as wide as, the cam surface to be ground is employed for grinding the cams. The cams are ground in succession by different axially adjacent grinding surface sections 43a, 43b and 44a, 44b of the grinding tool 18. The service life of the grinding tool is increased considerably and if a grinding belt 19 is employed as the grinding tool, its loading capacity is increased. Both features improve the profitability of the machine and of the process. A grinding disc may also by used instead of a belt. <IMAGE>
