我們过去在鍛造的时候都有些保守思想,鍛件工艺上本来規定的加工余量和公差一般都大一些,而同志們干活还按照工艺上的正公差鍛造。这样做叫做保險尺寸,万一鍛造出来的鍛件檢驗不合格,反正是正公差余量大,重新下爐鍛造几火,还可以达到負公差,于是也就合格了,对金屬材料的浪費和工时的損失都不考虑。今年五月份領导上号召我們提高技术,改进操作,修改旧的工艺規程,制定先进工艺,并且强調鍛工干活推行負公差鍛造。我們全車間同志响应这
We used to have some conservative ideas when forging. The allowances and tolerances that were originally required for forging workmanship were generally larger, and the work of comrades was also forged in accordance with the positive tolerance of workmanship. This is called the insurance size, if forgings forging test failed, anyway, is the positive tolerance margin, re-furnace forging a few fire, you can also reach negative tolerance, so they pass, the waste of metal materials and working hours Loss is not considered. In May this year, leaders called for us to improve our technology, improve our operations, revise the old process regulations, formulate advanced processes, and emphasize that we should work hard to carry out negative tolerance forging. Our whole workshop comrades respond to this
