數控銅(tong)排加(jia)工(gong)(gong)(gong)機的(de)(de)精(jing)密(mi)(mi)(mi)化是(shi)為了(le)(le)適應高新(xin)技(ji)(ji)術發展的(de)(de)需要，也是(shi)為了(le)(le)提(ti)高普通(tong)機電產品的(de)(de)性能、質量和可靠(kao)性，減少(shao)其裝配時的(de)(de)工(gong)(gong)(gong)作(zuo)量從而提(ti)高裝配效率(lv)的(de)(de)需要。數控銅(tong)排加(jia)工(gong)(gong)(gong)機新(xin)材料及新(xin)零件的(de)(de)出現(xian)(xian)，更(geng)高精(jing)度(du)要求的(de)(de)提(ti)出等(deng)都需要超(chao)(chao)(chao)精(jing)密(mi)(mi)(mi)加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝，發展新(xin)型超(chao)(chao)(chao)精(jing)密(mi)(mi)(mi)銅(tong)排加(jia)工(gong)(gong)(gong)機，完善(shan)現(xian)(xian)代(dai)超(chao)(chao)(chao)精(jing)密(mi)(mi)(mi)加(jia)工(gong)(gong)(gong)技(ji)(ji)術，以(yi)適應現(xian)(xian)代(dai)科技(ji)(ji)的(de)(de)發展，超(chao)(chao)(chao)精(jing)密(mi)(mi)(mi)加(jia)工(gong)(gong)(gong)主要包(bao)括超(chao)(chao)(chao)精(jing)密(mi)(mi)(mi)切削、超(chao)(chao)(chao)精(jing)密(mi)(mi)(mi)磨(mo)削、超(chao)(chao)(chao)精(jing)密(mi)(mi)(mi)研(yan)磨(mo)拋光以(yi)及超(chao)(chao)(chao)精(jing)密(mi)(mi)(mi)特種加(jia)工(gong)(gong)(gong)。

隨著現(xian)代科學技術(shu)的(de)(de)發(fa)(fa)展，對超精密加工(gong)技術(shu)不斷(duan)提(ti)出了新的(de)(de)要求(qiu)。從精密加工(gong)發(fa)(fa)展到超精密加工(gong)，是(shi)世界(jie)各工(gong)業強國(guo)致力發(fa)(fa)展的(de)(de)方向。數控銅(tong)排加工(gong)機(ji)精度(du)從微米級到亞微米級，乃至納米級，其(qi)應用范圍(wei)日(ri)趨廣泛。母(mu)線(xian)(xian)處于高電(dian)(dian)位，目(mu)前國(guo)內專門(men)用于高壓母(mu)線(xian)(xian)及(ji)電(dian)(dian)接(jie)觸發(fa)(fa)熱測(ce)(ce)量(liang)的(de)(de)儀(yi)器還很(hen)少(shao)。溫(wen)度(du)監測(ce)(ce)的(de)(de)主(zhu)要方法一是(shi)在(zai)電(dian)(dian)接(jie)觸表面涂一層隨溫(wen)度(du)變(bian)化顏色(se)的(de)(de)發(fa)(fa)光材(cai)料，通過觀(guan)察(cha)其(qi)顏色(se)變(bian)化來大致確(que)定(ding)溫(wen)度(du)范圍(wei)，這種方法準(zhun)確(que)度(du)低、可靠性差，不能進行(xing)定(ding)量(liang)測(ce)(ce)量(liang)；根據高電(dian)(dian)壓作(zuo)業環境下溫(wen)度(du)測(ce)(ce)量(liang)的(de)(de)特點，數控銅(tong)排加工(gong)機(ji)母(mu)線(xian)(xian)和電(dian)(dian)接(jie)觸溫(wen)度(du)測(ce)(ce)量(liang)裝置采取溫(wen)度(du)就地(di)測(ce)(ce)量(liang)，數據遙送地(di)面，由計(ji)算機(ji)進行(xing)處理的(de)(de)方法。
