　　鏡面拋光加工工(gong)藝主(zhu)要是用(yong)來降低工(gong)件的表面粗糙程度,對金屬工(gong)件進行(xing)選擇拋(pao)光工(gong)藝方(fang)法(fa)時,根(gen)據(ju)不同需求可以選不同的方(fang)法(fa),以下是拋(pao)光鏡面加工(gong)工(gong)藝常見的幾(ji)種方(fang)法(fa)。

　　電解拋光：

　　鏡(jing)面拋(pao)(pao)(pao)光(guang)加工廠家表示，電解拋(pao)(pao)(pao)光(guang)基本原(yuan)理(li)與(yu)化學(xue)拋(pao)(pao)(pao)光(guang)相同,即靠選擇(ze)性的(de)溶(rong)解材料表面微小(xiao)凸(tu)出部(bu)分(fen),使表面光(guang)滑。與(yu)化學(xue)拋(pao)(pao)(pao)光(guang)相比,可以(yi)消除陰極反應的(de)影響,效果較好(hao)。電化學(xue)拋(pao)(pao)(pao)光(guang)過程分(fen)為兩(liang)步(bu):

　　(1)、宏觀整平 溶解產物(wu)向電解液中擴(kuo)散,材料(liao)表面幾(ji)何(he)粗糙下(xia)降,Ra>1μm。

　　(2)、微(wei)觀平整 陽極極化,表面(mian)光亮度提高,Ra<1μm。

　　電致伸(shen)縮精整鏡面拋光：

　　作(zuo)為加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)新工(gong)(gong)(gong)(gong)(gong)藝(yi)，在(zai)很多(duo)(duo)種類金(jin)(jin)屬(shu)(shu)零部件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)方面(mian)具有(you)獨(du)特的(de)(de)(de)優勢。可(ke)替代傳(chuan)統的(de)(de)(de)磨床(chuang)、滾(gun)壓、鏜滾(gun)、珩磨、拋光(guang)(guang)機、砂(sha)帶(dai)機等其它金(jin)(jin)屬(shu)(shu)表面(mian)光(guang)(guang)整(zheng)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)設(she)備及工(gong)(gong)(gong)(gong)(gong)藝(yi);使(shi)金(jin)(jin)屬(shu)(shu)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)高光(guang)(guang)潔度加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)變得易如反掌。電(dian)(dian)致(zhi)伸縮(suo)精整(zheng)不僅僅可(ke)以(yi)拋光(guang)(guang)，還可(ke)以(yi)帶(dai)來(lai)很多(duo)(duo)附(fu)加(jia)(jia)的(de)(de)(de)好(hao)處：可(ke)使(shi)被加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)表面(mian)光(guang)(guang)潔度提(ti)高5級以(yi)上(粗糙度Ra值輕松達到(dao)0.1微(wei)米以(yi)下);且工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)的(de)(de)(de)表面(mian)顯微(wei)硬度提(ti)高5%-20%以(yi)上;并大(da)大(da)提(ti)高了工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)的(de)(de)(de)表面(mian)耐磨性(xing)和耐腐蝕性(xing)。延長工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)的(de)(de)(de)使(shi)用壽(shou)命(ming)，電(dian)(dian)致(zhi)伸縮(suo)精整(zheng)可(ke)用于(yu)處理各種不銹(xiu)鋼、銅、鋁、鈦合金(jin)(jin)及其它金(jin)(jin)屬(shu)(shu)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)。
