我厂过去一直沿用车削挑丝后淬火,再用螺纹磨床精加工的工艺来生产螺纹环规,生产周期长,效率低,成品率不高,因而环规供不应求,成为生产关键。为了解决这个问题,我厂采用了螺纹环规淬火后挑丝新工艺,环规精度达2a级,光洁度达▽8以上,完全符合图纸要 In the past, our factory used the turning quenching after pick-up of the wire, and then used the thread grinder finishing process to produce the thread ring gauge. The production cycle was long, the efficiency was low, and the finished product rate was not high. Therefore, the ring gauge was in short supply and became the key of production. In order to solve this problem, I plant the use of thread ring quenching after tapping new technology, ring gauge accuracy of 2a, finish ▽ 8 or more, in full compliance with the drawings
