湖光仪器厂某产品的分划圈,原在进口的刻度机上加工,效率很低,7分钟才能加工一件。由于加工数量很大,机床分度付精度损失较快,产品质量难以保征。该厂职工遵照毛主席“独立自主、自力更生”的方针,设计制造了一台简易刻线机。经过生产使用,效果较好。加工精度较高,产品要求圆周划线的累 Huguang Instrument Factory division of a product circle, the original scale machine imported processing, low efficiency, 7 minutes to process a. Due to the large number of processing, the accuracy of the machine sub-pay the loss of faster, difficult to maintain the quality of the product levy. The factory workers in accordance with Chairman Mao “independent, self-reliance,” the principle of design and manufacture of a simple engraving machine. After production use, the effect is better. Processing accuracy is higher, the product requires a circle crossed the tired
