五金加工就是(shi)將原材料(liao)(不(bu)銹鋼、銅料(liao)、鋁料(liao)、鐵料(liao))，用(yong)(yong)車床、銑床、鉆(zhan)床、磨(mo)床、拋(pao)(pao)光(guang)(guang)(guang)等(deng)(deng)機(ji)械按客戶的圖(tu)紙或樣品加(jia)工(gong)(gong)(gong)(gong)成為(wei)各種零(ling)(ling)件(jian)，如：螺絲 、馬達(da)軸、模(mo)型車零(ling)(ling)件(jian)、移動(dong)電源外殼等(deng)(deng)。五(wu)金表(biao)(biao)面加(jia)工(gong)(gong)(gong)(gong)細分(fen)可分(fen)為(wei)：五(wu)金噴漆加(jia)工(gong)(gong)(gong)(gong)、電鍍、表(biao)(biao)面拋(pao)(pao)光(guang)(guang)(guang)加(jia)工(gong)(gong)(gong)(gong)、五(wu)金腐(fu)蝕加(jia)工(gong)(gong)(gong)(gong)等(deng)(deng)等(deng)(deng)。拋(pao)(pao)光(guang)(guang)(guang)：原理是(shi)指通過有(you)規則溶(rong)解(jie)達(da)到光(guang)(guang)(guang)亮(liang)平滑；方法(fa)：利用(yong)(yong)機(ji)械、化(hua)學或電化(hua)學的作用(yong)(yong)，使(shi)工(gong)(gong)(gong)(gong)件(jian)表(biao)(biao)面粗糙度(du)降低，得(de)以是(shi)五(wu)金加(jia)工(gong)(gong)(gong)(gong)獲得(de)光(guang)(guang)(guang)亮(liang)、平整表(biao)(biao)面的加(jia)工(gong)(gong)(gong)(gong)方法(fa)。是(shi)利用(yong)(yong)拋(pao)(pao) 光(guang)(guang)(guang)工(gong)(gong)(gong)(gong)具和磨(mo)料(liao)顆粒或其他拋(pao)(pao)光(guang)(guang)(guang)介質(zhi)對工(gong)(gong)(gong)(gong)件(jian)表(biao)(biao)面進行的修(xiu)飾加(jia)工(gong)(gong)(gong)(gong)。

五金加(jia)工(gong)的(de)(de)(de)(de)氧(yang)化(hua)(hua)(hua)(hua)分為鋁硬質氧(yang)化(hua)(hua)(hua)(hua)、壓(ya)鑄鋁氧(yang)化(hua)(hua)(hua)(hua)、彩色(se)氧(yang)化(hua)(hua)(hua)(hua)、鋁陽(yang)極氧(yang)化(hua)(hua)(hua)(hua)、本色(se)氧(yang)化(hua)(hua)(hua)(hua)等(deng)。鈍化(hua)(hua)(hua)(hua)：原(yuan)理(li)(li)可以用(yong)薄膜(mo)理(li)(li)論來解釋，鈍化(hua)(hua)(hua)(hua)是由于金屬與(yu)氧(yang)化(hua)(hua)(hua)(hua)性(xing)物(wu)質作用(yong)，作用(yong)時在金屬表面生(sheng)成 一種非常薄的(de)(de)(de)(de)、致密(mi)的(de)(de)(de)(de)、覆蓋性(xing)能良(liang)好的(de)(de)(de)(de)、牢固地吸附在金屬 表面上(shang)的(de)(de)(de)(de)鈍化(hua)(hua)(hua)(hua)膜(mo)。與(yu)傳統的(de)(de)(de)(de)物(wu)理(li)(li)封閉法相(xiang)比，鈍化(hua)(hua)(hua)(hua)處(chu)理(li)(li)后具有絕-對不(bu)增加(jia)工(gong)件厚度(du)和(he)改(gai)變顏色(se)的(de)(de)(de)(de)特點、提高了(le)產(chan)品的(de)(de)(de)(de)精密(mi)度(du)和(he)附加(jia)值(zhi)，使操作更方便。

背(bei)膠(jiao)：背(bei)膠(jiao)是(shi)郵(you)票的重要特征之一。機加(jia)工(gong)：車削(xue)(xue)加(jia)工(gong)、刨削(xue)(xue)加(jia)工(gong)、銑(xian)削(xue)(xue)加(jia)工(gong)、磨削(xue)(xue)加(jia)工(gong)，滾牙(ya)(ya)：牙(ya)(ya)使(shi)用兩個帶(dai)有(you)螺(luo)紋的棍子(zi)來擠壓被加(jia)工(gong)的工(gong)件，使(shi)零件表面被壓出螺(luo)紋。攻(gong)牙(ya)(ya)：攻(gong)牙(ya)(ya)就(jiu)是(shi)板(ban)牙(ya)(ya)，是(shi)用來加(jia)工(gong)或修理外螺(luo)紋的，它的內(nei)部是(shi)有(you)螺(luo)紋的，可手工(gong)加(jia)工(gong)也可以用在套絲機上。電鍍：電鍍分為掛鍍、滾鍍、連續(xu)鍍和刷鍍等方式(shi)，主(zhu)要與(yu)待鍍件的尺(chi)寸(cun)和批量有(you)關(guan)。
