五金加工就是(shi)(shi)將原材料(liao)(不銹(xiu)鋼、銅料(liao)、鋁料(liao)、鐵料(liao))，用(yong)車床、銑床、鉆床、磨床、拋(pao)(pao)光(guang)等(deng)機械按客戶的(de)(de)(de)圖紙或樣品加工(gong)(gong)(gong)成為各(ge)種零(ling)件，如：螺絲 、馬達軸(zhou)、模型車零(ling)件、移動電源外殼等(deng)。五(wu)金(jin)表面(mian)加工(gong)(gong)(gong)細分可(ke)分為：五(wu)金(jin)噴漆加工(gong)(gong)(gong)、電鍍、表面(mian)拋(pao)(pao)光(guang)加工(gong)(gong)(gong)、五(wu)金(jin)腐蝕加工(gong)(gong)(gong)等(deng)等(deng)。拋(pao)(pao)光(guang)：原理是(shi)(shi)指通過有規則(ze)溶解達到光(guang)亮(liang)(liang)平(ping)滑；方法(fa)：利用(yong)機械、化學或電化學的(de)(de)(de)作用(yong)，使(shi)工(gong)(gong)(gong)件表面(mian)粗糙度降低，得(de)以是(shi)(shi)五(wu)金(jin)加工(gong)(gong)(gong)獲得(de)光(guang)亮(liang)(liang)、平(ping)整表面(mian)的(de)(de)(de)加工(gong)(gong)(gong)方法(fa)。是(shi)(shi)利用(yong)拋(pao)(pao) 光(guang)工(gong)(gong)(gong)具和(he)磨料(liao)顆粒(li)或其他(ta)拋(pao)(pao)光(guang)介(jie)質對工(gong)(gong)(gong)件表面(mian)進行的(de)(de)(de)修飾加工(gong)(gong)(gong)。

五金(jin)加(jia)工的(de)(de)(de)氧化(hua)(hua)(hua)(hua)(hua)分(fen)為(wei)鋁硬質氧化(hua)(hua)(hua)(hua)(hua)、壓鑄鋁氧化(hua)(hua)(hua)(hua)(hua)、彩色氧化(hua)(hua)(hua)(hua)(hua)、鋁陽極(ji)氧化(hua)(hua)(hua)(hua)(hua)、本色氧化(hua)(hua)(hua)(hua)(hua)等。鈍(dun)化(hua)(hua)(hua)(hua)(hua)：原理可以(yi)用(yong)薄(bo)膜(mo)理論來(lai)解釋，鈍(dun)化(hua)(hua)(hua)(hua)(hua)是由于金(jin)屬與(yu)氧化(hua)(hua)(hua)(hua)(hua)性(xing)物質作用(yong)，作用(yong)時(shi)在金(jin)屬表面(mian)生成(cheng) 一種非常薄(bo)的(de)(de)(de)、致(zhi)密(mi)的(de)(de)(de)、覆(fu)蓋(gai)性(xing)能良(liang)好的(de)(de)(de)、牢固地吸附(fu)在金(jin)屬 表面(mian)上的(de)(de)(de)鈍(dun)化(hua)(hua)(hua)(hua)(hua)膜(mo)。與(yu)傳統的(de)(de)(de)物理封(feng)閉法(fa)相(xiang)比，鈍(dun)化(hua)(hua)(hua)(hua)(hua)處理后具(ju)有絕-對不(bu)增加(jia)工件厚(hou)度(du)和改變顏色的(de)(de)(de)特點、提高了產(chan)品(pin)的(de)(de)(de)精密(mi)度(du)和附(fu)加(jia)值(zhi)，使操(cao)作更方便。

背膠(jiao)(jiao)：背膠(jiao)(jiao)是郵票的(de)(de)重(zhong)要(yao)特(te)征之(zhi)一。機加(jia)(jia)(jia)(jia)(jia)工(gong)：車(che)削加(jia)(jia)(jia)(jia)(jia)工(gong)、刨削加(jia)(jia)(jia)(jia)(jia)工(gong)、銑削加(jia)(jia)(jia)(jia)(jia)工(gong)、磨削加(jia)(jia)(jia)(jia)(jia)工(gong)，滾牙：牙使(shi)用(yong)兩個帶有螺紋(wen)的(de)(de)棍子來擠壓(ya)被加(jia)(jia)(jia)(jia)(jia)工(gong)的(de)(de)工(gong)件，使(shi)零件表面(mian)被壓(ya)出螺紋(wen)。攻(gong)牙：攻(gong)牙就是板牙，是用(yong)來加(jia)(jia)(jia)(jia)(jia)工(gong)或修理外(wai)螺紋(wen)的(de)(de)，它的(de)(de)內(nei)部是有螺紋(wen)的(de)(de)，可手工(gong)加(jia)(jia)(jia)(jia)(jia)工(gong)也可以用(yong)在套絲機上。電鍍：電鍍分(fen)為掛鍍、滾鍍、連(lian)續鍍和刷鍍等方(fang)式(shi)，主要(yao)與(yu)待鍍件的(de)(de)尺寸和批量有關。
