在“独立自主,自力更生”的方针指引下,我厂广大职工会同有关研究部门及机床厂,研制成功了一条加工3～5#电机轴自动生产线。生产拍节为一分钟。这条自动线虽然对发展我国电机生产起到了较大的作用,但在长期生产实践中,发现这条线的最后一道工序──车转子外圆,常因硅钢片迭成的 Guided by the principle of “Independent and Self-Reliance”, a large number of workers in our factory, together with relevant research departments and machine tool plants, successfully developed a 3 ~ 5 # automatic production line for motor shafts. Production beat for one minute. Although this automatic line has played a greater role in the development of China’s motor production, in the long-term production practice, the last process of this line was found - the outer circumference of the rotor of a vehicle, often due to the superposition of silicon steel sheets
