1990年12月11日,中国兵器工业总公司在我院主持召开了《模具型腔光整加工》科研课题部级技术鉴定会,全国模具制造方面的一些著名教授和专家参加了鉴定会。我国的模具工业同世界先进的工业国相比,差距较大,主要是模具制造周期长,精度低,使用寿命短。该课题组针对这些问题研制了一套完整、高效、多功能的设备及工作液等,实现了复合加工,对我国模具行业技术进步具有很大促进作用。专家们鉴定认勾,DFM-1型计算机复合模具抛光机具有电解锉削、超声抛光、电解超声复合抛光等功能,配有模具光整加工工艺编制专家系统,设计思想新颖,结构合理,功能多,性能好。该机研制的成功,可使光整加工效率较钳工抛光提高1～10倍,表面粗糙度在Ra0.1μm
December 11, 1990, China Ordnance Industry Corporation presided over in our hospital held a “mold cavity finishing” research project ministry-level technical appraisal, the country’s mold manufacturing some famous professors and experts attended the appraisal. China’s mold industry compared with the world’s most advanced industrial countries, the gap is large, mainly the mold manufacturing cycle is long, low accuracy, short service life. The research group for these problems developed a complete, efficient and versatile equipment and working fluid, etc., to achieve a complex processing, mold technology in China has greatly contributed to technological progress. DFM-1 computer composite mold polishing machine with electrolytic file cutting, ultrasonic polishing, electrolytic ultrasonic polishing and other functions, equipped with a die finishing process expert system, the design of innovative, rational structure, multi-function Good performance. The success of the development of the aircraft, finishing efficiency can be polished more than fitter 1 to 10 times the surface roughness Ra0.1μm
