Beschreibung
Zusammenfassung:	A method for the manufacture or machining of the tooth system of straight or helically toothed, externally or internally toothed, nonhardened or hardened workpiece with a toothed tool, the tooth flanks of which are coated with a cubic boron nitride (CBN). The workpiece and the tool roll along with a single-flank contact and are supported by a guide-gear pair which also roll along with a single-flank contact. The contacting flanks of the workpiece-tool pair are the mating flanks for the contacting flanks of the guide-gear pair. To protect the CNB-coating, the tool is already driven at a speed which is necessary for an optimum chip removal before the tool tooth flanks start to work on the workpiece tooth flanks.
