　　鏡面拋光加工工藝(yi)主要是用來(lai)降(jiang)低(di)工件(jian)的表面粗糙程度,對金屬工件(jian)進(jin)行選擇拋光工藝(yi)方法時(shi),根(gen)據不同(tong)(tong)需求可以選不同(tong)(tong)的方法,以下是拋光鏡面加工工藝(yi)常見的幾種(zhong)方法。

　　電解拋光：

　　鏡面(mian)拋(pao)光(guang)加工廠家表(biao)示，電解拋(pao)光(guang)基本(ben)原(yuan)理(li)與化(hua)學拋(pao)光(guang)相同(tong),即(ji)靠(kao)選(xuan)擇性(xing)的溶解材料表(biao)面(mian)微小凸出部分(fen),使表(biao)面(mian)光(guang)滑。與化(hua)學拋(pao)光(guang)相比,可(ke)以消(xiao)除陰(yin)極(ji)反應的影響,效果較好。電化(hua)學拋(pao)光(guang)過程分(fen)為(wei)兩步:

　　(1)、宏(hong)觀(guan)整(zheng)平(ping) 溶(rong)解(jie)產物向電(dian)解(jie)液中擴散,材料表面幾何粗糙下降,Ra>1μm。

　　(2)、微(wei)觀(guan)平整(zheng) 陽(yang)極(ji)極(ji)化,表面光亮度提高(gao),Ra<1μm。

　　電致伸縮精(jing)整鏡面拋光(guang)：

　　作為加(jia)(jia)工(gong)(gong)(gong)的(de)新工(gong)(gong)(gong)藝，在很多(duo)種(zhong)類金屬(shu)零部件加(jia)(jia)工(gong)(gong)(gong)方面具有獨特的(de)優勢。可(ke)(ke)替代傳(chuan)統(tong)的(de)磨(mo)床、滾壓、鏜滾、珩磨(mo)、拋(pao)光(guang)機(ji)、砂帶機(ji)等其(qi)(qi)它金屬(shu)表(biao)面光(guang)整(zheng)加(jia)(jia)工(gong)(gong)(gong)設備及(ji)工(gong)(gong)(gong)藝;使(shi)金屬(shu)工(gong)(gong)(gong)件高(gao)光(guang)潔度(du)加(jia)(jia)工(gong)(gong)(gong)變得易如反掌。電致伸縮(suo)精整(zheng)不(bu)僅僅可(ke)(ke)以(yi)拋(pao)光(guang)，還可(ke)(ke)以(yi)帶來很多(duo)附加(jia)(jia)的(de)好(hao)處(chu)：可(ke)(ke)使(shi)被加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)件表(biao)面光(guang)潔度(du)提高(gao)5級以(yi)上(粗糙度(du)Ra值輕(qing)松(song)達(da)到0.1微米以(yi)下(xia));且(qie)工(gong)(gong)(gong)件的(de)表(biao)面顯微硬度(du)提高(gao)5%-20%以(yi)上;并大(da)大(da)提高(gao)了(le)工(gong)(gong)(gong)件的(de)表(biao)面耐磨(mo)性和耐腐蝕性。延(yan)長工(gong)(gong)(gong)件的(de)使(shi)用(yong)(yong)壽命，電致伸縮(suo)精整(zheng)可(ke)(ke)用(yong)(yong)于處(chu)理(li)各種(zhong)不(bu)銹鋼(gang)、銅(tong)、鋁、鈦合(he)金及(ji)其(qi)(qi)它金屬(shu)工(gong)(gong)(gong)件。
