螺旋双径机用铰刀加工对象是在1Cr18Ni9Ti材料的零件上加工Φ16~(+0.12)、180毫米长的通孔,要求表面光洁度▽7。以前使用的是直齿机用标准铰刀,存在两个技术难题: 1.铰刀寿命短,每把铰刀仅能加工3～5个孔,个别的可加工7个孔。 2.铰出的孔多数呈现圆度不佳,严重的甚至出现波浪式多边形。经改进和近两年的生产实践考验,采用螺旋双径机用铰刀有显著效果。铰刀寿命提高了,
Spiral dual-path machine reamer object is processed in 1Cr18Ni9Ti parts of the material Φ16 ~ (+0.12), 180 mm long through-hole, requiring surface finish ▽ 7. Previously used is a standard reamer for spur gear, there are two technical problems: 1. Reamer life is short, each reamer can only process 3 to 5 holes, individual can process 7 holes. 2. Most of the hinged holes show poor roundness, serious or even wavy polygons. After the improvement and the production practice in the past two years, the spiral double-path machine reamer has a significant effect. Reamer life expectancy increased,
