西安国营昆仑机械厂在科研产品的试制生产中,某产品六头螺母的加工长期以来是个“细脖子”,车工排扣采用的是原始的加工方法,不但费时、费力,而且产品质量和互换难以保证,加工一个零件光刀就得反复300余次,每次进刀量不得大于0.1mm,还需由技术等级高的工人承担,常常由于这道工序的加工,影响了工厂月计划生产任务的完成。
Xi’an state-run Kunlun Machinery Factory in the trial production of scientific research products, the processing of a product six nuts has long been a “thin neck”, lathe using the original processing method is not only time-consuming, laborious, and product quality and exchange It is difficult to guarantee that the machining of a part knife has to be repeated more than 300 times and the amount of each shot must not exceed 0.1mm. It also needs to be undertaken by workers with high technical level. Often, due to the processing of this procedure, the monthly production plan of the factory is affected carry out.
