随着轴承工业的发展,辗扩工艺在轴承套圈毛坯的生产中日益广泛地得到应用,对辗扩设备—扩孔机也提出了更高的要求.以前我厂生产的D51—160型扩孔机,结构比较复杂,制造工艺性较差,机床的性能也不能满足使用要求.在厂党委的正确领导下,以工人为主体的三结合设计小组,遵循毛主席关于“中国人民有志气,有能力,一定要在不远的将来,赶上和超过世界先进水平” 的教导,狠批了“爬行主义”、“洋奴哲学”,发扬了
With the development of the bearing industry, rolling process in the bearing ring rough production increasingly widely used, the rolling equipment - reaming machine also made higher requirements. In the past I plant the D51-160 expansion Hole machine, the structure is more complex, manufacturing technology is poor, the performance of the machine can not meet the requirements.Under the correct leadership of the factory party committees, the three combined design team with workers as the main body, follow Chairman Mao on “Chinese people ambition, Capable, must in the near future, catch up with and surpass the world’s advanced level ”, severely criticized the“ creepism ”and“ foreign slave philosophy ”and carried forward
