全国高技术产业化协作组织（ＣＨＣ）推出了双圆锥前刀面插齿刀。该刀适应于各机械制造厂、各工具厂。 插齿是齿轮加工的重要方法之一，传统上使用的插齿刀切削角度过小，不能发挥其最佳性能。增大切削角度又带来过大的齿形误差，使被加工齿轮的齿形精度降低。本插齿刀用双圆锥 National High-Tech Industrial Collaboration (CHC) has introduced a double cone rake face shaper. The knife adapted to the machinery factory, the tool factory. Gear shaper is an important method of gear processing, the traditional use of gear shaper cutting angle is too small, can not play its best performance. Increase the cutting angle has brought too much tooth-shaped error, the gear to be processed to reduce the accuracy of tooth shape. The gear cutter with double cone
