我厂机修车间职工,通过活学活用毛主席著作,解放了思想,克服各种困难,采取工人、技术人员和革命领导干部三结合的方法,自己动手,经过反复试验、改进,终于制造成功了齿轮淬火机,解决了由于没有高频淬火机而影响检修的问题。 Through the study and application of Chairman Mao’s works, our factory mechanics workshop liberated our thinking and overcame all kinds of difficulties. We adopted the three-pronged approach of workers, technicians and revolutionary leading cadres. Through trial and error experiments, we finally succeeded in manufacturing Gear hardening machine, to solve the problem because there is no high-frequency hardening machine and affect maintenance.
