五金加工就是(shi)將原材料(不銹(xiu)鋼(gang)、銅料、鋁料、鐵料)，用(yong)(yong)車床(chuang)、銑床(chuang)、鉆床(chuang)、磨(mo)床(chuang)、拋(pao)(pao)光(guang)(guang)等機(ji)械按(an)客戶的圖紙(zhi)或樣品加(jia)工(gong)(gong)(gong)(gong)成為各(ge)種零件，如：螺絲 、馬(ma)達(da)軸、模型車零件、移動電源外(wai)殼等。五金表(biao)面加(jia)工(gong)(gong)(gong)(gong)細分可(ke)分為：五金噴漆(qi)加(jia)工(gong)(gong)(gong)(gong)、電鍍、表(biao)面拋(pao)(pao)光(guang)(guang)加(jia)工(gong)(gong)(gong)(gong)、五金腐蝕加(jia)工(gong)(gong)(gong)(gong)等等。拋(pao)(pao)光(guang)(guang)：原理是(shi)指通過有規則溶解達(da)到光(guang)(guang)亮平滑；方法：利用(yong)(yong)機(ji)械、化(hua)學或電化(hua)學的作(zuo)用(yong)(yong)，使工(gong)(gong)(gong)(gong)件表(biao)面粗糙度(du)降低，得以是(shi)五金加(jia)工(gong)(gong)(gong)(gong)獲得光(guang)(guang)亮、平整表(biao)面的加(jia)工(gong)(gong)(gong)(gong)方法。是(shi)利用(yong)(yong)拋(pao)(pao) 光(guang)(guang)工(gong)(gong)(gong)(gong)具和磨(mo)料顆粒或其他(ta)拋(pao)(pao)光(guang)(guang)介質對工(gong)(gong)(gong)(gong)件表(biao)面進行的修(xiu)飾加(jia)工(gong)(gong)(gong)(gong)。

五金加工的(de)(de)(de)(de)氧(yang)(yang)化(hua)(hua)分為鋁硬(ying)質氧(yang)(yang)化(hua)(hua)、壓(ya)鑄(zhu)鋁氧(yang)(yang)化(hua)(hua)、彩色氧(yang)(yang)化(hua)(hua)、鋁陽極氧(yang)(yang)化(hua)(hua)、本(ben)色氧(yang)(yang)化(hua)(hua)等。鈍(dun)化(hua)(hua)：原理可以用薄膜理論來解釋，鈍(dun)化(hua)(hua)是由于(yu)金屬與氧(yang)(yang)化(hua)(hua)性物質作(zuo)用，作(zuo)用時在金屬表(biao)面生成 一種非常薄的(de)(de)(de)(de)、致密的(de)(de)(de)(de)、覆(fu)蓋性能(neng)良好(hao)的(de)(de)(de)(de)、牢固地吸附(fu)在金屬 表(biao)面上(shang)的(de)(de)(de)(de)鈍(dun)化(hua)(hua)膜。與傳統的(de)(de)(de)(de)物理封閉(bi)法相比(bi)，鈍(dun)化(hua)(hua)處理后具(ju)有(you)絕(jue)-對(dui)不增加工件厚度(du)和(he)改(gai)變顏色的(de)(de)(de)(de)特點、提(ti)高(gao)了產品(pin)的(de)(de)(de)(de)精(jing)密度(du)和(he)附(fu)加值，使操作(zuo)更方便。

背膠(jiao)：背膠(jiao)是郵(you)票的(de)(de)重要特征之一。機(ji)加(jia)(jia)工(gong)：車削(xue)加(jia)(jia)工(gong)、刨削(xue)加(jia)(jia)工(gong)、銑削(xue)加(jia)(jia)工(gong)、磨削(xue)加(jia)(jia)工(gong)，滾(gun)(gun)牙：牙使(shi)用(yong)(yong)兩個帶有(you)螺(luo)紋(wen)的(de)(de)棍子來(lai)(lai)擠壓被加(jia)(jia)工(gong)的(de)(de)工(gong)件，使(shi)零件表面被壓出(chu)螺(luo)紋(wen)。攻(gong)牙：攻(gong)牙就是板牙，是用(yong)(yong)來(lai)(lai)加(jia)(jia)工(gong)或修理外螺(luo)紋(wen)的(de)(de)，它的(de)(de)內部是有(you)螺(luo)紋(wen)的(de)(de)，可(ke)手(shou)工(gong)加(jia)(jia)工(gong)也可(ke)以用(yong)(yong)在套絲機(ji)上。電鍍(du)(du)：電鍍(du)(du)分為掛鍍(du)(du)、滾(gun)(gun)鍍(du)(du)、連續鍍(du)(du)和(he)刷鍍(du)(du)等方式(shi)，主要與待鍍(du)(du)件的(de)(de)尺寸和(he)批量(liang)有(you)關。
