MD80/90机头转包生产特种工艺达标攻关

Tackle Key Problems During Specific Processes Got Approval for MD80/90 Nose Subcontract Production

本文论述了特种工艺的定义及其在CAC MD80/90机头制造中的地位和作用,并重点阐述了为满足MD机头转包生产所需的特种工艺种类和在生产MD机头前高温测量技术、表面处理工艺技术、热处理工艺技术和焊接工艺技术与西方先进技术的关键差距所在。经过技术改造和特种工艺技术攻关顺利通过了麦克唐纳-道格拉斯公司的专家鉴定和工艺评审。展望了我国特种工艺技术的发展方向。一年多来的生产实践表明,国际合作是提高特种工艺技术和管理现代化的有效途径。

The definition of specific process and its position and function in CAC MD8O/90 nose productionhave been described.The specific processes required to meet the requirements of MD nose subcontract pro-duction and the main difference in the measuring technique of high temperature,surface treatment,heattreatment,and welding technology between Chengdu aircraft company and Mcdonnell-Douglas aircraftcompany before CAC manufactures MD nose are stated specially.We passed the experts certification andprocess survey of Mcdonnell-Douglas by facility modification and tackling the key problems of processestechnology.Look into the developing direction of our specific process technology,we found that interna-tion cooperational is a effective way in enhancing the specific process technology and modernizing the man-agement of us.
