我厂每年承担的汽车标准件生产任务中,各种不同规格的槽形螺母占有相当大的比重。槽形螺母三个开口销槽的加工,一般在铣床上采用切口片铣刀进行铣削。过去多年来,由于工艺方法落后,每只螺母需经过三次走刀铣出三槽,辅助时间长,效率低,占用铣床多台,还不能完成生产任务,因而长期来一直成为生产中的薄弱环节。去年,我厂职工在厂党委的领导下,以批修整风为纲,深入进行了思想政治路线教育,进一 I assume every year the factory car standard parts production tasks, a variety of different sizes of trough nuts occupy a large proportion. Slotted nut three open pin slot processing, the general use of a milling cutter on the milling cutter. In the past many years, due to the backward technological process, each nut had to go through three passes to make three troughs. The auxiliary time was long, the efficiency was low, it took more than one milling machine and could not complete the production tasks. Therefore, it has long been a weak link in production . Last year, under the leadership of the factory party committee, our factory workers, taking the practice of rectifying and rectifying the rectification as the key link, conducted in-depth education on ideological and political routes and entered a
