对于φ100～400,深度L≤605毫来的大花键孔的加工,可采用单刀插削或单刀拉削,但精度差,效率低;采用花键拉刀拉削,需要很长拉刀,制造复杂,成本高,而且需要大动力拉床。为此,我厂在总结设计和制造小型花键插刀的基础上,为四川东方电机厂设计并共同制造了加工键槽外径240毫米、底径225毫米、键宽28毫米、齿数为12的多刀刃大型花键孔插刀,其加工精度达精密级,累积误差0.035毫米,光洁度达
For φ100 ~ 400, the depth of L ≤ 605 milliseconds to the large spline hole processing, single-insert or single-broach can be used, but the accuracy is poor, low efficiency; using spline broaching broaching need a long broach, Complex manufacturing, high cost, and need large power broaching. Therefore, on the basis of summarizing the design and manufacture of small spline knife, our factory designs and co-manufactures for Sichuan Dongfang Electrical Machinery Factory, the outer diameter of keyway is 240mm, the bottom diameter is 225mm, the key width is 28mm and the number of teeth is 12 Multi-blade large spline hole knife, the processing precision of precision grade, the cumulative error of 0.035 mm, finish up to
