五金加工就是(shi)將原材料(不銹鋼、銅料、鋁料、鐵料)，用(yong)(yong)(yong)車(che)床(chuang)、銑床(chuang)、鉆床(chuang)、磨床(chuang)、拋(pao)光(guang)(guang)(guang)等(deng)(deng)機(ji)械(xie)(xie)按客戶的(de)圖(tu)紙或樣(yang)品(pin)加(jia)工(gong)(gong)(gong)(gong)成(cheng)為(wei)各種零(ling)件(jian)，如：螺絲 、馬達(da)軸、模型(xing)車(che)零(ling)件(jian)、移動電(dian)源外(wai)殼等(deng)(deng)。五(wu)金(jin)表面(mian)加(jia)工(gong)(gong)(gong)(gong)細分可分為(wei)：五(wu)金(jin)噴(pen)漆(qi)加(jia)工(gong)(gong)(gong)(gong)、電(dian)鍍、表面(mian)拋(pao)光(guang)(guang)(guang)加(jia)工(gong)(gong)(gong)(gong)、五(wu)金(jin)腐蝕加(jia)工(gong)(gong)(gong)(gong)等(deng)(deng)等(deng)(deng)。拋(pao)光(guang)(guang)(guang)：原理是(shi)指(zhi)通過有(you)規則(ze)溶(rong)解達(da)到光(guang)(guang)(guang)亮(liang)平(ping)滑；方法(fa)：利(li)用(yong)(yong)(yong)機(ji)械(xie)(xie)、化學(xue)或電(dian)化學(xue)的(de)作用(yong)(yong)(yong)，使工(gong)(gong)(gong)(gong)件(jian)表面(mian)粗糙(cao)度降低，得以是(shi)五(wu)金(jin)加(jia)工(gong)(gong)(gong)(gong)獲得光(guang)(guang)(guang)亮(liang)、平(ping)整(zheng)表面(mian)的(de)加(jia)工(gong)(gong)(gong)(gong)方法(fa)。是(shi)利(li)用(yong)(yong)(yong)拋(pao) 光(guang)(guang)(guang)工(gong)(gong)(gong)(gong)具(ju)和磨料顆粒或其(qi)他拋(pao)光(guang)(guang)(guang)介質(zhi)對工(gong)(gong)(gong)(gong)件(jian)表面(mian)進(jin)行的(de)修飾加(jia)工(gong)(gong)(gong)(gong)。

五(wu)金加工的氧(yang)(yang)化(hua)(hua)(hua)(hua)分為鋁(lv)硬質(zhi)(zhi)氧(yang)(yang)化(hua)(hua)(hua)(hua)、壓鑄(zhu)鋁(lv)氧(yang)(yang)化(hua)(hua)(hua)(hua)、彩色(se)氧(yang)(yang)化(hua)(hua)(hua)(hua)、鋁(lv)陽極氧(yang)(yang)化(hua)(hua)(hua)(hua)、本色(se)氧(yang)(yang)化(hua)(hua)(hua)(hua)等。鈍(dun)化(hua)(hua)(hua)(hua)：原理(li)可以用薄(bo)膜理(li)論(lun)來解(jie)釋，鈍(dun)化(hua)(hua)(hua)(hua)是由于(yu)金屬(shu)(shu)與氧(yang)(yang)化(hua)(hua)(hua)(hua)性(xing)物(wu)質(zhi)(zhi)作用，作用時在(zai)金屬(shu)(shu)表(biao)面(mian)生成(cheng) 一種(zhong)非常薄(bo)的、致密(mi)的、覆蓋性(xing)能良好(hao)的、牢固(gu)地吸附在(zai)金屬(shu)(shu) 表(biao)面(mian)上的鈍(dun)化(hua)(hua)(hua)(hua)膜。與傳統的物(wu)理(li)封閉法(fa)相(xiang)比，鈍(dun)化(hua)(hua)(hua)(hua)處(chu)理(li)后具(ju)有絕(jue)-對不增加工件厚度和改變顏色(se)的特點(dian)、提高了產(chan)品的精密(mi)度和附加值，使(shi)操作更方(fang)便(bian)。

背(bei)膠(jiao)：背(bei)膠(jiao)是郵票(piao)的重要(yao)特征之(zhi)一。機加(jia)(jia)(jia)工(gong)：車削(xue)加(jia)(jia)(jia)工(gong)、刨削(xue)加(jia)(jia)(jia)工(gong)、銑削(xue)加(jia)(jia)(jia)工(gong)、磨削(xue)加(jia)(jia)(jia)工(gong)，滾牙(ya)：牙(ya)使用(yong)兩(liang)個帶有螺紋的棍子來擠壓被加(jia)(jia)(jia)工(gong)的工(gong)件，使零件表面被壓出(chu)螺紋。攻牙(ya)：攻牙(ya)就是板牙(ya)，是用(yong)來加(jia)(jia)(jia)工(gong)或修理外螺紋的，它的內部(bu)是有螺紋的，可手工(gong)加(jia)(jia)(jia)工(gong)也可以用(yong)在套絲機上。電(dian)鍍(du)(du)：電(dian)鍍(du)(du)分(fen)為掛(gua)鍍(du)(du)、滾鍍(du)(du)、連續(xu)鍍(du)(du)和(he)刷鍍(du)(du)等(deng)方(fang)式，主要(yao)與(yu)待鍍(du)(du)件的尺寸和(he)批量有關。
