日前，從“高檔(dang)數控(kong)機(ji)床(chuang)與基(ji)礎制(zhi)造裝備”國家(jia)科技重大(da)專項實施管理辦公(gong)室傳來喜訊，由(you)陜西秦(qin)川(chuan)機(ji)床(chuang)工(gong)(gong)具(ju)集團(tuan)牽(qian)頭承擔的(de)“立式銑車復合加工(gong)(gong)中心”課題(ti)，在用(yong)戶(hu)現(xian)場西安(an)三航(hang)動力(li)科技有(you)限公(gong)司通過了國家(jia)驗收。
銑(xian)車復(fu)(fu)合與(yu)車銑(xian)復(fu)(fu)合加(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心(xin)是(shi)集(ji)高(gao)精(jing)度(du)(du)、高(gao)效率于一體(ti)的(de)先進加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝(yi)技術(shu)方案，是(shi)航空發動機機匣、整體(ti)葉盤、鼓風(feng)機葉輪、葉片等復(fu)(fu)雜曲面零件加(jia)工(gong)(gong)(gong)(gong)的(de)關鍵(jian)設備。經國家機床(chuang)質量(liang)監督檢驗中(zhong)(zhong)心(xin)檢測，課題研發產品的(de)幾(ji)何精(jing)度(du)(du)、位置(zhi)精(jing)度(du)(du)、工(gong)(gong)(gong)(gong)作(zuo)精(jing)度(du)(du)等指標都(dou)達到任務(wu)合同書(shu)的(de)要求(qiu)，機床(chuang)平均無故障時(shi)間（MTBF）超過900小時(shi)。用戶表(biao)示，立式銑(xian)車復(fu)(fu)合加(jia)工(gong)(gong)(gong)(gong)中(zhong)(zhong)心(xin)使(shi)用效果可與(yu)國外同類機床(chuang)相媲美，能夠替代進口。
