我厂生产的315型起动机外壳圆周上共有φ3～φ12.7大小不等孔8个,两端面有二个定位槽.我们原来加工方法是采用铣床铣二定位槽,用2A125钻床加用圆钻模和快换套钻8个孔.由于生产量的增加,原来的加工方法跟不上生产的需要,必须改进设备.毛主席教导我们:“我们是主张自力更生的.我们希望有外援,但是我们不能依赖它,我们依靠自己的努力,依靠全体军民的创造力.”我们革新组全体同志遵循主席这一教
I plant 315 starter shell circumference a total of φ3 ~ φ12.7 size ranging from holes 8, two ends have two positioning slots. Our original processing method is to use milling milling two positioning slots, with 2A125 drilling plus round Drilling and quick change sets of drill holes 8. Because of the increase in production, the original processing methods can not keep up with the production needs, we must improve the equipment.Mr Chairman Mao taught us: “We are advocating self-reliance .We hope to have foreign aid, but We can not rely on it, and we rely on our own efforts to rely on the creativity of all our military and civilian people. ”All of our comrades in the reform group follow the principle of chairmanship
