目前,我厂钢球毛坯生产是在自动压球机或钢球轧机上成型,然后经过锉削加工方法去掉环带和两极点,再进行必要的磨削加工。这种锉削加工方法是苏修的落后工艺,生产效率比较低,噪声大,劳动条件较差,产品质量不高。为了改变这种落后工艺,我厂八车间组成了以工人为主体的三结合技术革新小组,对钢球毛坯初压型胎窝进行了改革,并试制成功一台钢球毛坯精整机,经试用效果良好,钢球经精整后增强了金属密度,提高了耐腐蚀性和耐磨性,压碎负荷也有了显著提高。钢球精整机的创制成功,打破了苏修落后工艺的陈规陋习,为我国钢球生产闯出了一条新路。这是毛主席“打破洋框框,走自己工业发展道路”的伟大教导在我厂结成的丰硕成果,是毛主席革命路线的伟大胜利。 At present, I plant ball blank production is automatic pressure ball machine or ball mill molding, and then after filing method to remove the ring and poles, and then the necessary grinding. This filing method is the Soviet Union’s backward process, the production efficiency is relatively low, noise, poor working conditions, product quality is not high. In order to change this backward technology, I plant eight workshop composed of workers as the mainstay of the three combination of technical innovation group, the initial blanket of steel ball blanks were reform, and trial success of a ball blanking finishing machine, the Trial results are good, the steel ball after finishing the metal density increased, improved corrosion resistance and wear resistance, crushing load has also been significantly improved. The successful creation of the ball finishing machine broke the stereotypes of lagging behind the Soviet Union and broke a new road for the production of steel balls in China. This is a great accomplishment made by Chairman Mao Zedong in the great teachings of “breaking the framework of the world and taking the path of industrial development of our own” and is a great victory of Chairman Mao’s revolutionary line.
