航空部六二五所和航天部一一九厂共同研制的加工导弹舵机本体的设备和工艺已通过鉴定。参加鉴定会的有航空部、航天部、兵器部、机械工业部和辽宁省所属厂所院校共二十多个单位40多名代表。代表们听取了研制单位的技术报告,查阅了全部图纸资料、试验报告,并经现场加工零件,实测了零件及机床精度,经过认真讨论一致认为:三工位精密镗床和四工位组合机床解决了导弹舵机本体生产中存在的“三低一高”问题,即加工精度和光洁度低,刀具寿命低,生产效率低,废品率高。一一九厂
The equipment and technology for processing the missile steering gear body jointly developed by 625 Ministry of Aviation and 119 Aerospace Department have passed the appraisal. Participate in the appraisal will be the Ministry of Aviation, Ministry of Space, Ministry of Weaponry, Ministry of Machinery Industry and factories owned by Liaoning Province, a total of more than 20 units more than 40 representatives. Representatives listened to the technical report of the development unit, access to all drawings and information, test reports, and the on-site processing of parts, measured the accuracy of parts and machine tools, after careful discussion agreed that: three-position precision boring machine and four-station combination of machine tools to solve The “three low and one high” problems existed in the production of the missile steering gear, that is, the machining accuracy and finish are low, the tool life is low, the production efficiency is low, and the rejection rate is high.
