五金加工就是(shi)將原材料(liao)(不銹鋼、銅料(liao)、鋁料(liao)、鐵(tie)料(liao))，用(yong)(yong)車(che)床(chuang)(chuang)、銑床(chuang)(chuang)、鉆(zhan)床(chuang)(chuang)、磨床(chuang)(chuang)、拋(pao)光(guang)(guang)(guang)(guang)等(deng)機械(xie)按客戶的(de)圖紙或樣品加工(gong)(gong)成(cheng)為各種零件(jian)，如：螺絲 、馬達軸、模型車(che)零件(jian)、移動(dong)電(dian)源外殼等(deng)。五金表(biao)面(mian)(mian)(mian)加工(gong)(gong)細分可分為：五金噴漆加工(gong)(gong)、電(dian)鍍、表(biao)面(mian)(mian)(mian)拋(pao)光(guang)(guang)(guang)(guang)加工(gong)(gong)、五金腐蝕加工(gong)(gong)等(deng)等(deng)。拋(pao)光(guang)(guang)(guang)(guang)：原理是(shi)指通過有規(gui)則(ze)溶解達到光(guang)(guang)(guang)(guang)亮平(ping)滑；方法(fa)：利(li)用(yong)(yong)機械(xie)、化(hua)學或電(dian)化(hua)學的(de)作用(yong)(yong)，使工(gong)(gong)件(jian)表(biao)面(mian)(mian)(mian)粗糙度降(jiang)低，得(de)以(yi)是(shi)五金加工(gong)(gong)獲得(de)光(guang)(guang)(guang)(guang)亮、平(ping)整表(biao)面(mian)(mian)(mian)的(de)加工(gong)(gong)方法(fa)。是(shi)利(li)用(yong)(yong)拋(pao) 光(guang)(guang)(guang)(guang)工(gong)(gong)具和磨料(liao)顆粒(li)或其(qi)他拋(pao)光(guang)(guang)(guang)(guang)介質(zhi)對工(gong)(gong)件(jian)表(biao)面(mian)(mian)(mian)進行(xing)的(de)修飾(shi)加工(gong)(gong)。

五金(jin)(jin)加(jia)(jia)工(gong)的(de)氧(yang)(yang)化(hua)分為(wei)鋁(lv)硬質氧(yang)(yang)化(hua)、壓(ya)鑄鋁(lv)氧(yang)(yang)化(hua)、彩色(se)氧(yang)(yang)化(hua)、鋁(lv)陽極氧(yang)(yang)化(hua)、本(ben)色(se)氧(yang)(yang)化(hua)等。鈍(dun)(dun)化(hua)：原(yuan)理(li)可(ke)以(yi)用薄(bo)膜(mo)理(li)論(lun)來解釋，鈍(dun)(dun)化(hua)是由于金(jin)(jin)屬(shu)與(yu)氧(yang)(yang)化(hua)性物(wu)(wu)質作(zuo)用，作(zuo)用時在金(jin)(jin)屬(shu)表面(mian)(mian)生成 一種非常薄(bo)的(de)、致密的(de)、覆蓋性能(neng)良好的(de)、牢固(gu)地吸附在金(jin)(jin)屬(shu) 表面(mian)(mian)上的(de)鈍(dun)(dun)化(hua)膜(mo)。與(yu)傳統的(de)物(wu)(wu)理(li)封閉法相比，鈍(dun)(dun)化(hua)處理(li)后具有絕-對不(bu)增加(jia)(jia)工(gong)件厚度(du)和改變顏(yan)色(se)的(de)特點、提高了(le)產(chan)品(pin)的(de)精(jing)密度(du)和附加(jia)(jia)值，使操作(zuo)更方便。

背膠(jiao)(jiao)：背膠(jiao)(jiao)是郵票的(de)(de)重(zhong)要(yao)(yao)特征之一(yi)。機加工(gong)(gong)：車削加工(gong)(gong)、刨削加工(gong)(gong)、銑削加工(gong)(gong)、磨(mo)削加工(gong)(gong)，滾(gun)牙(ya)：牙(ya)使用兩(liang)個帶有螺(luo)(luo)紋(wen)(wen)的(de)(de)棍(gun)子(zi)來(lai)擠壓(ya)(ya)被(bei)加工(gong)(gong)的(de)(de)工(gong)(gong)件(jian)，使零件(jian)表(biao)面被(bei)壓(ya)(ya)出螺(luo)(luo)紋(wen)(wen)。攻牙(ya)：攻牙(ya)就是板(ban)牙(ya)，是用來(lai)加工(gong)(gong)或修理外螺(luo)(luo)紋(wen)(wen)的(de)(de)，它(ta)的(de)(de)內部是有螺(luo)(luo)紋(wen)(wen)的(de)(de)，可(ke)手(shou)工(gong)(gong)加工(gong)(gong)也可(ke)以用在套絲(si)機上。電鍍(du)：電鍍(du)分為掛鍍(du)、滾(gun)鍍(du)、連續鍍(du)和刷鍍(du)等方(fang)式(shi)，主要(yao)(yao)與待鍍(du)件(jian)的(de)(de)尺寸和批(pi)量有關。
