五金加工就是將(jiang)原(yuan)材(cai)料(liao)(不銹鋼、銅料(liao)、鋁(lv)料(liao)、鐵料(liao))，用(yong)車(che)床、銑床、鉆床、磨床、拋光(guang)等機(ji)械(xie)按(an)客戶的(de)圖紙或樣品加工(gong)(gong)成為(wei)各種零(ling)件，如：螺絲 、馬(ma)達軸(zhou)、模(mo)型車(che)零(ling)件、移動電(dian)源外殼等。五(wu)金表面(mian)(mian)加工(gong)(gong)細分(fen)可分(fen)為(wei)：五(wu)金噴漆加工(gong)(gong)、電(dian)鍍、表面(mian)(mian)拋光(guang)加工(gong)(gong)、五(wu)金腐蝕加工(gong)(gong)等等。拋光(guang)：原(yuan)理是指通過有規則溶(rong)解達到光(guang)亮平滑；方法(fa)：利(li)用(yong)機(ji)械(xie)、化學(xue)或電(dian)化學(xue)的(de)作用(yong)，使工(gong)(gong)件表面(mian)(mian)粗糙(cao)度(du)降低(di)，得(de)以是五(wu)金加工(gong)(gong)獲得(de)光(guang)亮、平整(zheng)表面(mian)(mian)的(de)加工(gong)(gong)方法(fa)。是利(li)用(yong)拋 光(guang)工(gong)(gong)具和磨料(liao)顆粒或其他拋光(guang)介質對工(gong)(gong)件表面(mian)(mian)進行的(de)修飾加工(gong)(gong)。

五金加工(gong)的(de)(de)氧(yang)(yang)化(hua)(hua)(hua)(hua)分為鋁(lv)(lv)硬質氧(yang)(yang)化(hua)(hua)(hua)(hua)、壓鑄(zhu)鋁(lv)(lv)氧(yang)(yang)化(hua)(hua)(hua)(hua)、彩色氧(yang)(yang)化(hua)(hua)(hua)(hua)、鋁(lv)(lv)陽(yang)極氧(yang)(yang)化(hua)(hua)(hua)(hua)、本色氧(yang)(yang)化(hua)(hua)(hua)(hua)等。鈍化(hua)(hua)(hua)(hua)：原理(li)可以用薄(bo)膜理(li)論(lun)來解釋，鈍化(hua)(hua)(hua)(hua)是由于(yu)金屬與氧(yang)(yang)化(hua)(hua)(hua)(hua)性物質作用，作用時在金屬表面生(sheng)成 一(yi)種(zhong)非(fei)常(chang)薄(bo)的(de)(de)、致密(mi)的(de)(de)、覆蓋性能良(liang)好(hao)的(de)(de)、牢固地(di)吸附在金屬 表面上的(de)(de)鈍化(hua)(hua)(hua)(hua)膜。與傳統的(de)(de)物理(li)封閉法相比(bi)，鈍化(hua)(hua)(hua)(hua)處理(li)后具(ju)有絕-對不增加工(gong)件厚度(du)和改變顏(yan)色的(de)(de)特點、提高了產(chan)品的(de)(de)精(jing)密(mi)度(du)和附加值，使操作更方便。

背(bei)膠(jiao)：背(bei)膠(jiao)是郵票的(de)重要特(te)征之一。機加工(gong)(gong)(gong)(gong)：車削加工(gong)(gong)(gong)(gong)、刨削加工(gong)(gong)(gong)(gong)、銑削加工(gong)(gong)(gong)(gong)、磨削加工(gong)(gong)(gong)(gong)，滾牙(ya)：牙(ya)使用兩個帶有(you)(you)螺(luo)紋(wen)(wen)的(de)棍子來擠壓(ya)被加工(gong)(gong)(gong)(gong)的(de)工(gong)(gong)(gong)(gong)件(jian)，使零件(jian)表面被壓(ya)出(chu)螺(luo)紋(wen)(wen)。攻(gong)牙(ya)：攻(gong)牙(ya)就是板(ban)牙(ya)，是用來加工(gong)(gong)(gong)(gong)或修(xiu)理外螺(luo)紋(wen)(wen)的(de)，它(ta)的(de)內部是有(you)(you)螺(luo)紋(wen)(wen)的(de)，可手工(gong)(gong)(gong)(gong)加工(gong)(gong)(gong)(gong)也(ye)可以(yi)用在套絲機上。電鍍(du)：電鍍(du)分為掛鍍(du)、滾鍍(du)、連續鍍(du)和刷鍍(du)等方式，主要與(yu)待鍍(du)件(jian)的(de)尺(chi)寸和批量有(you)(you)關。
