在批林批孔运动的推动下,我们实行工人、技术人员、领导干部三结合,发挥敢想敢干的革命精神,经过反复试验,在较短的时间内,试验成功了人造金刚石磨头。三号磨头经过一段时间的使用,性能良好,完全可以代替碳化硅磨头,而且具有磨削效率高、耐磨性好的特点。为水磨石生产的机械化,为生产更多更好的水磨石创造了条件。一、问题的提出随着毛主席革命路线的胜利,国内外形势一派大好,水磨石的出口、援外和国内的需要量急剧增长。在大好形势的推动下,经 Driven by the pro-Lin bidding exercise, we implemented the combination of workers, technicians and leading cadres to give full play to the revolutionary spirit of daring to think and dare. After repeated tests, we succeeded in testing the artificial diamond grinding heads in a relatively short period of time. After a period of grinding head on the 3rd, the performance is good, can replace the silicon carbide grinding head, but also with high grinding efficiency, good wear resistance. For the production of terrazzo mechanization, to produce more and better terrazzo to create the conditions. I. PROBLEM PROPOSITION With the victory of Chairman Mao’s revolutionary line, the situation at home and abroad is fantastic. Exports of terrazzo, foreign aid and domestic demand have risen sharply. Under the impetus of the good situation, after
