我厂原生产的万向节轴承滚针套,是用热轧轴承钢棒料,经退火,无心荒车后,在1261M六轴自动车床上车制的。这种工艺材料利用率极低,以804705/01为例,仅达27.8％,大量的轴承钢被车为废屑,同时也大大降低车削效率。针对这种情况,我厂广大革命职工遵照毛主席:“要节约闹革命”,“备战、备荒、为人民”,的伟大教导,在“鞍钢宪法”光辉旗帜的指引下,与轴承研究所等单位在65年底着手进行了用渗碳钢冷挤压滚针套新工艺试验,参加试验人员反复学习了毛主席的光辉哲学著作“矛盾论”和“实践论”,经过由物质到精神,由精神到物质的多次反复,终于在无产阶级文化大革命中试验成功了,今年正式大批投
I plant the original production of universal joint bearings needle roller sets, is the use of hot-rolled bearing steel bar material, after annealing, careless wreck, the 1261M six-axis automatic lathe system. This process material utilization is very low, to 804705/01, for example, only 27.8%, a large number of bearing steel was scrap car, but also greatly reduce the turning efficiency. In response to this situation, the vast majority of our revolutionary workers obey the great teachings of Chairman Mao: “To save the revolution,” “prepare for war, prepare for the poor, and serve the people.” Under the guidance of the glorious banner of the Anshan Steel Constitution, At the end of 65, the unit embarked on a trial of a new technology of cold extrusion needle roller sleeve with carburizing steel. Participants in the experiment repeatedly studied Chairman Mao’s glorious philosophical book Paradox and Practice Theory. From substance to spirit, Many times the spiritual to material repetition has finally succeeded in the Great Proletarian Cultural Revolution. This year, a large number of formal castings
