拋光的本質是使用拋光材料通過物理作(zuo)用或電、磁及(ji)化(hua)學方(fang)(fang)法使工件表面光滑(hua)的(de)研磨工藝(yi)。拋(pao)(pao)光可分(fen)為粗(cu)拋(pao)(pao)、中拋(pao)(pao)和精拋(pao)(pao)，拋(pao)(pao)光的(de)每個過程用的(de)拋(pao)(pao)光材料是(shi)不(bu)(bu)(bu)同的(de)，甚至不(bu)(bu)(bu)同拋(pao)(pao)光的(de)過程中的(de)地點也是(shi)分(fen)開的(de)，比如說粗(cu)拋(pao)(pao)地點和精拋(pao)(pao)地點分(fen)是(shi)在不(bu)(bu)(bu)同的(de)地方(fang)(fang)完成的(de)。

還需要(yao)(yao)注意(yi)的(de)是(shi)使用不同拋光材料(liao)(liao)(liao)的(de)每(mei)道(dao)拋光工(gong)(gong)(gong)序完成后(hou)必(bi)須要(yao)(yao)清(qing)理上一道(dao)工(gong)(gong)(gong)序在工(gong)(gong)(gong)件(jian)表(biao)面(mian)的(de)殘留物。拋光材料(liao)(liao)(liao)對工(gong)(gong)(gong)件(jian)進(jin)行粗(cu)拋后(hou)達(da)到了粗(cu)拋的(de)工(gong)(gong)(gong)藝(yi)要(yao)(yao)求(qiu)，接下來就要(yao)(yao)進(jin)行精拋，一旦進(jin)行精拋，工(gong)(gong)(gong)件(jian)就需要(yao)(yao)在環境要(yao)(yao)求(qiu)更高拋光材料(liao)(liao)(liao)更細的(de)無(wu)塵車間(jian)進(jin)行，確(que)保(bao)空氣中(zhong)無(wu)灰塵微粒粘在工(gong)(gong)(gong)件(jian)表(biao)面(mian)。

精拋工(gong)(gong)(gong)藝完成(cheng)后工(gong)(gong)(gong)件(jian)表(biao)面(mian)要做好(hao)防塵處(chu)理(li)，同(tong)時還需要清除(chu)拋光材料及其他添加物的(de)(de)殘留，保證工(gong)(gong)(gong)件(jian)表(biao)面(mian)潔凈(jing)，最(zui)后的(de)(de)話就(jiu)是(shi)對(dui)工(gong)(gong)(gong)件(jian)噴涂防銹(xiu)涂層，防止工(gong)(gong)(gong)件(jian)由于長時間不用或工(gong)(gong)(gong)作環(huan)境的(de)(de)原因發生生銹(xiu)，影響使用壽命。
