遵照毛主席关于“独立自主、自力更生”的伟大教导,一九七○年我厂在兄弟工厂的协助下,制成一台热轧齿轮滚刀毛坯三辊轧机,目前已批量生产,为我厂能进行高速钢的成型轧制,实现少无切削新工艺,迈出了新的一步。过去我们加工一把中等规格的齿轮滚刀,用车床加工螺旋扣形,需要工时60多分钟。采用轧制成型新技术,加工五把需工时20秒,提高工效几十倍,同时还可以节省材 Following Chairman Mao’s great teaching on “independence, self-reliance ”, in 1970, with the help of our brother factory, our factory made a three-high mill for hot rolled gear hob cutter and has been mass-produced for me Plant can be high-speed steel forming rolling, no cutting new technology to achieve a new step. In the past, we machined a medium-sized gear hob that used a lathe to make a spiral-shaped button that required more than 60 minutes of man-hours. Using rolling new technology, processing five to work 20 seconds to improve work efficiency several times, but also can save material
