The machine adopts full digital control,. And with EGB electronic gear box, it replaces the function of ordinary machine tools to exchange various gears. Through the software control can realize the internal gear, external gear, helical gear and other process switching, but also can realize the drum, taper and additional asymmetric features of the gear processing, but also can be applied to the scraping processing of the hard tooth surface, can be partially replaced by the grinding process, especially the internal gear grinding.
