在伟大领袖毛主席关于“工业学大庆”的号召下,我厂广大革命职工大搞技术革新,敢想敢干,革新了水泵轴承轴心加工工艺。 以前水泵轴承轴心是采用热轧棒料,其加工工艺复杂,要先经过旋风车削,把φ18毫米的棒料毛坯车至φ17毫米,然后割断（刀口宽有3.5～4毫米）,手工磨轴心尖头以及车断面等,材料浪费不少。 现在,采用冷拉棒料（冷拉至φ16.5毫米）,以一次“冲断”,代替原来的割断和手工磨尖头。节省了外圆的车加工。
Under the call of Chairman Mao, the great leader, on “Daqing in Industry”, the vast majority of revolutionary workers in our factory engage in technological innovation and dare to think hard and make innovations in the processing of pump bearing shaft. Previous pump bearing shaft is the use of hot-rolled bar stock, the processing complexity of the process, the first cyclone turning, the φ18 mm bar stock rough to φ17 mm, and then cut off (knife width 3.5 ~ 4 mm), manual grinding Apex and car section, a lot of material waste. Now, using cold-drawn bar stock (cold-drawn to φ16.5 mm), a “punch” replaces the original cut and hand-polished tip. Save the cylindrical car processing.
