五金加工就是(shi)將原(yuan)材料(不銹(xiu)鋼、銅料、鋁料、鐵料)，用(yong)(yong)(yong)車床(chuang)(chuang)、銑床(chuang)(chuang)、鉆床(chuang)(chuang)、磨(mo)床(chuang)(chuang)、拋(pao)光等(deng)(deng)(deng)機(ji)械按客(ke)戶的圖紙(zhi)或樣品加(jia)工(gong)(gong)(gong)成為各種零件，如：螺(luo)絲(si) 、馬達(da)(da)軸、模型車零件、移動電(dian)(dian)源外殼等(deng)(deng)(deng)。五(wu)金(jin)表(biao)(biao)面(mian)加(jia)工(gong)(gong)(gong)細分可分為：五(wu)金(jin)噴漆加(jia)工(gong)(gong)(gong)、電(dian)(dian)鍍、表(biao)(biao)面(mian)拋(pao)光加(jia)工(gong)(gong)(gong)、五(wu)金(jin)腐(fu)蝕加(jia)工(gong)(gong)(gong)等(deng)(deng)(deng)等(deng)(deng)(deng)。拋(pao)光：原(yuan)理是(shi)指(zhi)通過(guo)有規則(ze)溶解達(da)(da)到光亮平(ping)滑；方法：利(li)(li)用(yong)(yong)(yong)機(ji)械、化學或電(dian)(dian)化學的作用(yong)(yong)(yong)，使工(gong)(gong)(gong)件表(biao)(biao)面(mian)粗(cu)糙度(du)降(jiang)低，得(de)以是(shi)五(wu)金(jin)加(jia)工(gong)(gong)(gong)獲(huo)得(de)光亮、平(ping)整表(biao)(biao)面(mian)的加(jia)工(gong)(gong)(gong)方法。是(shi)利(li)(li)用(yong)(yong)(yong)拋(pao) 光工(gong)(gong)(gong)具和磨(mo)料顆粒或其(qi)他拋(pao)光介質(zhi)對工(gong)(gong)(gong)件表(biao)(biao)面(mian)進行(xing)的修飾(shi)加(jia)工(gong)(gong)(gong)。

五金加(jia)工(gong)的(de)(de)(de)氧(yang)(yang)化(hua)(hua)分為鋁(lv)硬質氧(yang)(yang)化(hua)(hua)、壓鑄鋁(lv)氧(yang)(yang)化(hua)(hua)、彩(cai)色氧(yang)(yang)化(hua)(hua)、鋁(lv)陽極氧(yang)(yang)化(hua)(hua)、本色氧(yang)(yang)化(hua)(hua)等。鈍化(hua)(hua)：原理(li)(li)可以(yi)用薄膜理(li)(li)論來解釋，鈍化(hua)(hua)是由(you)于金屬與氧(yang)(yang)化(hua)(hua)性物(wu)質作用，作用時在金屬表(biao)面生成 一(yi)種非常薄的(de)(de)(de)、致密的(de)(de)(de)、覆蓋性能良好的(de)(de)(de)、牢固地吸附(fu)在金屬 表(biao)面上的(de)(de)(de)鈍化(hua)(hua)膜。與傳(chuan)統的(de)(de)(de)物(wu)理(li)(li)封(feng)閉法相(xiang)比，鈍化(hua)(hua)處理(li)(li)后(hou)具有(you)絕-對不增加(jia)工(gong)件厚度和(he)改變顏色的(de)(de)(de)特(te)點、提高了產品的(de)(de)(de)精密度和(he)附(fu)加(jia)值，使(shi)操作更方(fang)便。

背(bei)膠：背(bei)膠是(shi)郵(you)票的(de)(de)重要特征之一。機加(jia)工(gong)(gong)(gong)(gong)：車削(xue)加(jia)工(gong)(gong)(gong)(gong)、刨削(xue)加(jia)工(gong)(gong)(gong)(gong)、銑削(xue)加(jia)工(gong)(gong)(gong)(gong)、磨削(xue)加(jia)工(gong)(gong)(gong)(gong)，滾牙：牙使用(yong)兩個帶有(you)(you)螺紋(wen)的(de)(de)棍子來擠壓被加(jia)工(gong)(gong)(gong)(gong)的(de)(de)工(gong)(gong)(gong)(gong)件(jian)，使零件(jian)表面被壓出螺紋(wen)。攻(gong)牙：攻(gong)牙就是(shi)板牙，是(shi)用(yong)來加(jia)工(gong)(gong)(gong)(gong)或(huo)修理外螺紋(wen)的(de)(de)，它(ta)的(de)(de)內(nei)部是(shi)有(you)(you)螺紋(wen)的(de)(de)，可手工(gong)(gong)(gong)(gong)加(jia)工(gong)(gong)(gong)(gong)也可以用(yong)在套絲機上。電鍍(du)(du)：電鍍(du)(du)分為掛鍍(du)(du)、滾鍍(du)(du)、連續鍍(du)(du)和(he)(he)刷鍍(du)(du)等方式，主要與待鍍(du)(du)件(jian)的(de)(de)尺寸和(he)(he)批量(liang)有(you)(you)關。
