本厂机械车间因铣床较少,螺钉及螺帽的六方一向是在刨床上加工,但刨床生产率低、质量差,不易保证六方准确度。尤其是螺钉,在夹持及加工上都很费劲。去年年底,我们去大连化学厂参观了他们在车床上加工六方的装置后,考虑到我厂机械车间的情况,决定也试制一台,现在已基本试制成功,并移交车间投入生产。也许这个经验对其他兄弟厂矿有些用处,所以把它介绍出 The factory machinery shop due to less milling machine, screw and nut six-party has always been in the planer processing, but planer production rate is low, poor quality, not easy to ensure the accuracy of the six parties. Screws in particular are very laborious in clamping and machining. Late last year, we visited the Dalian Chemical Plant visited the six-party machine on the lathe, taking into account the situation of our plant machinery shop, the decision is also a trial of a trial has now been successfully completed and transferred to the workshop into production. Perhaps this experience is of some use to other brother factories and mines, so introduce it
