In order to meet the positioning requirements of high-precision gear processing, CNC lathe is used in the processing of gear blank, and mechanical clamping is used without regrinding the turning tool. The simultaneous processing of the hole diameter, end face and outer diameter is realized under one clamping, which not only ensures the perpendicularity requirements of the inner hole and the end face, but also ensures the small size dispersion of the large batch of gear blank production. Thus, the accuracy of gear blank is improved and the machining quality of subsequent gear is ensured. In addition, the high efficiency of CNC lathe processing also greatly reduces the number of equipment, good economy.
