五金加工就是將原(yuan)(yuan)材料(liao)(不銹鋼、銅料(liao)、鋁料(liao)、鐵料(liao))，用(yong)車床(chuang)、銑(xian)床(chuang)、鉆床(chuang)、磨床(chuang)、拋(pao)(pao)光(guang)(guang)等機械按客戶的圖(tu)紙或(huo)樣(yang)品加(jia)(jia)工(gong)成為各種(zhong)零件(jian)，如：螺絲 、馬達軸、模型車零件(jian)、移動(dong)電(dian)源外(wai)殼等。五金(jin)表面(mian)加(jia)(jia)工(gong)細分(fen)可(ke)分(fen)為：五金(jin)噴漆(qi)加(jia)(jia)工(gong)、電(dian)鍍、表面(mian)拋(pao)(pao)光(guang)(guang)加(jia)(jia)工(gong)、五金(jin)腐蝕加(jia)(jia)工(gong)等等。拋(pao)(pao)光(guang)(guang)：原(yuan)(yuan)理是指(zhi)通(tong)過有規則溶(rong)解達到光(guang)(guang)亮(liang)平滑；方法：利(li)用(yong)機械、化學(xue)或(huo)電(dian)化學(xue)的作用(yong)，使工(gong)件(jian)表面(mian)粗糙度降低，得(de)以是五金(jin)加(jia)(jia)工(gong)獲得(de)光(guang)(guang)亮(liang)、平整表面(mian)的加(jia)(jia)工(gong)方法。是利(li)用(yong)拋(pao)(pao) 光(guang)(guang)工(gong)具和磨料(liao)顆(ke)粒或(huo)其他(ta)拋(pao)(pao)光(guang)(guang)介質對工(gong)件(jian)表面(mian)進行的修飾加(jia)(jia)工(gong)。

五金加(jia)工的(de)氧(yang)化(hua)(hua)(hua)分(fen)為(wei)鋁(lv)硬質(zhi)氧(yang)化(hua)(hua)(hua)、壓鑄(zhu)鋁(lv)氧(yang)化(hua)(hua)(hua)、彩色(se)氧(yang)化(hua)(hua)(hua)、鋁(lv)陽(yang)極氧(yang)化(hua)(hua)(hua)、本(ben)色(se)氧(yang)化(hua)(hua)(hua)等。鈍化(hua)(hua)(hua)：原理(li)(li)可以用(yong)薄膜(mo)理(li)(li)論來解釋，鈍化(hua)(hua)(hua)是由于金屬(shu)(shu)與(yu)氧(yang)化(hua)(hua)(hua)性物質(zhi)作用(yong)，作用(yong)時在(zai)金屬(shu)(shu)表面(mian)生成 一種(zhong)非(fei)常(chang)薄的(de)、致密的(de)、覆蓋性能良好的(de)、牢固地吸附在(zai)金屬(shu)(shu) 表面(mian)上的(de)鈍化(hua)(hua)(hua)膜(mo)。與(yu)傳統(tong)的(de)物理(li)(li)封閉法相比，鈍化(hua)(hua)(hua)處理(li)(li)后(hou)具有絕-對不增加(jia)工件厚度(du)和改(gai)變顏色(se)的(de)特點、提高了產品的(de)精密度(du)和附加(jia)值，使操作更方(fang)便。

背(bei)膠：背(bei)膠是(shi)(shi)郵票(piao)的(de)(de)重(zhong)要特(te)征之一(yi)。機加(jia)(jia)工(gong)(gong)(gong)：車削(xue)加(jia)(jia)工(gong)(gong)(gong)、刨削(xue)加(jia)(jia)工(gong)(gong)(gong)、銑削(xue)加(jia)(jia)工(gong)(gong)(gong)、磨(mo)削(xue)加(jia)(jia)工(gong)(gong)(gong)，滾牙(ya)(ya)：牙(ya)(ya)使用兩個帶(dai)有螺紋(wen)的(de)(de)棍子來(lai)擠壓被加(jia)(jia)工(gong)(gong)(gong)的(de)(de)工(gong)(gong)(gong)件(jian)(jian)，使零件(jian)(jian)表面(mian)被壓出螺紋(wen)。攻牙(ya)(ya)：攻牙(ya)(ya)就(jiu)是(shi)(shi)板牙(ya)(ya)，是(shi)(shi)用來(lai)加(jia)(jia)工(gong)(gong)(gong)或修(xiu)理(li)外螺紋(wen)的(de)(de)，它的(de)(de)內部(bu)是(shi)(shi)有螺紋(wen)的(de)(de)，可(ke)手工(gong)(gong)(gong)加(jia)(jia)工(gong)(gong)(gong)也可(ke)以用在套絲機上。電(dian)鍍(du)(du)：電(dian)鍍(du)(du)分為掛鍍(du)(du)、滾鍍(du)(du)、連續鍍(du)(du)和刷鍍(du)(du)等方式，主要與(yu)待鍍(du)(du)件(jian)(jian)的(de)(de)尺寸和批(pi)量有關(guan)。
