“120”齿輸箱生产关键之一是加工摩擦片内齿形,由于摩擦片採用高强度合金钢,材料很硬,用通常的插齿办法,刀具寿命短,生产效率低。用拉刀拉,不但要做又粗又大的拉刀,而且我厂没有这样的设备,这个办法又不行,怎么办?粉冶车间革命职工分析了影响内齿加工各方面的因素,遵循毛主席“研究任何过程,如果存在着两个以上矛盾的复杂过程的话,就要用全力找出它的主要矛盾·捉住了这个
One of the keys to the “120” gearbox production is the processing of the toothed profile of the friction plate. Since the friction plate is made of high-strength alloy steel, the material is very hard. With the conventional gear-cutting method, the tool has a short service life and low production efficiency. Pull with a broach, not only to do bold and big broach, but I plant does not have such equipment, this approach can not do, how to do? Revolutionary staff of powder metallurgy workshop analysis of various factors affecting the internal tooth processing, follow the hair Chairman "To study any process, if there is a complicated process of more than two contradictions, we should try our best to find out its main contradiction.
