在伟大领袖毛主席关于“独立自主、自力更生”,“打破洋框框,走自己工业发展道路”的光辉思想指导下,我厂二车间铣工小组的革命工人,发扬敢想、敢干的革命精神,群策群力,土法上马,克服重重困难,制造成功齿轮粗铣机。齿轮加工中对分齿精度的要求是严格的。过去加工齿轮大多数是用格里森机床,粗铣切齿的关键,也是要求分度精确。黄河150型汽车半轴齿轮,就是一个齿一个齿地铣出来的,加工时有振动,质量差,效率低,而且工人劳动强度很大。革命工人对这种少慢差费的陈旧工艺看在眼里,急在心上。
Guided by the glorious ideology of great leader Chairman Mao on “independence, self-reliance,” “breaking the framework of the foreign trade and following our own industrial development path,” the revolutionary workers of the second workshop milling group of our factory carry forward the revolutionary spirit of daring to think and dare to do their own best and make concerted efforts , Soil law launched, to overcome numerous difficulties, the successful manufacture of gear roughed mill. Gear teeth on the processing accuracy requirements are strict. In the past, most of the machining gears were made with Gleason machines, the key to roughing and cutting teeth, and the need for precise indexing. Yellow 150 car semi-axle gear, is a tooth milling toothed, processing, vibration, poor quality, low efficiency, but also a great labor intensity. The revolutionary workers are blind to this slow-moving old process.
