细长轴由于其刚性差,加工时容易弯曲和振动,高速切削难度较大。笔者根据多年的实际经验,对细长轴的高速切削加工作了一些总结,现介绍如下。1工艺过程 (1)检查毛坯弯曲度,如全长超过3～4m须进行调直。 (2)按图纸要求截出毛坯,伸入车床主轴孔,尾部用卡盘找正,车端面,打中心孔;然后调头,用同样方法找正,并车出与卡爪等长的工艺台 Slender shaft because of its poor rigidity, easy bending and vibration processing, high-speed cutting more difficult. The author based on years of practical experience, the slender shaft made some high-speed machining, are presented below. 1 Process (1) Check the curvature of rough, such as the total length of more than 3 ~ 4m to be straightened. (2) according to the requirements of the drawings cut off rough, into the lathe spindle hole, the tail with the chuck to find the car face, hit the center hole; then U-turn, with the same method to find positive,
