Research on the Tooth-Surface Controlling and Honing Machining of the Ultral-Precision CBN Gear

With the popularization of precision-machining process by the hard tooth-surface gear, special machining tools have also been developed rapidly, which is mainly manifested in as aspects as the application of new materials and cutting tools’ coating technology, the mature of ultra-hard-grain CBN tools’ preparation technology, and the pefecting day by day of tool-structure design and tool-integration technology and so on. This topic introduces the CBN gear’s honingmachining characteristic and designing principles. And it also contains the application status of the ultra-precision tooth surface and the importance of the tooth-surface morphology in the process of gearing transmitting. At the same time, this topic briefly describes several common processes and key processing technologies in the modern gear-manufacturing
