五金加工就(jiu)是將原材料(liao)(liao)(不銹鋼、銅(tong)料(liao)(liao)、鋁料(liao)(liao)、鐵料(liao)(liao))，用(yong)車床、銑床、鉆床、磨床、拋(pao)(pao)光(guang)(guang)等(deng)機械按客戶的(de)圖紙或樣品加(jia)(jia)(jia)工(gong)(gong)成(cheng)為各種零(ling)件，如：螺(luo)絲 、馬達軸、模型車零(ling)件、移動電源(yuan)外殼(ke)等(deng)。五(wu)(wu)金表(biao)面(mian)加(jia)(jia)(jia)工(gong)(gong)細分(fen)可分(fen)為：五(wu)(wu)金噴漆加(jia)(jia)(jia)工(gong)(gong)、電鍍、表(biao)面(mian)拋(pao)(pao)光(guang)(guang)加(jia)(jia)(jia)工(gong)(gong)、五(wu)(wu)金腐蝕加(jia)(jia)(jia)工(gong)(gong)等(deng)等(deng)。拋(pao)(pao)光(guang)(guang)：原理(li)是指通過有(you)規則(ze)溶解達到(dao)光(guang)(guang)亮平(ping)滑；方(fang)法：利(li)(li)用(yong)機械、化(hua)學或電化(hua)學的(de)作用(yong)，使工(gong)(gong)件表(biao)面(mian)粗(cu)糙(cao)度降低，得以是五(wu)(wu)金加(jia)(jia)(jia)工(gong)(gong)獲(huo)得光(guang)(guang)亮、平(ping)整表(biao)面(mian)的(de)加(jia)(jia)(jia)工(gong)(gong)方(fang)法。是利(li)(li)用(yong)拋(pao)(pao) 光(guang)(guang)工(gong)(gong)具和磨料(liao)(liao)顆粒或其他拋(pao)(pao)光(guang)(guang)介質(zhi)對工(gong)(gong)件表(biao)面(mian)進行的(de)修飾加(jia)(jia)(jia)工(gong)(gong)。

五金(jin)加工(gong)的(de)氧(yang)化(hua)(hua)(hua)(hua)(hua)分為鋁硬質(zhi)(zhi)氧(yang)化(hua)(hua)(hua)(hua)(hua)、壓鑄鋁氧(yang)化(hua)(hua)(hua)(hua)(hua)、彩色氧(yang)化(hua)(hua)(hua)(hua)(hua)、鋁陽(yang)極(ji)氧(yang)化(hua)(hua)(hua)(hua)(hua)、本色氧(yang)化(hua)(hua)(hua)(hua)(hua)等。鈍化(hua)(hua)(hua)(hua)(hua)：原(yuan)理可(ke)以(yi)用(yong)薄膜理論來(lai)解釋，鈍化(hua)(hua)(hua)(hua)(hua)是(shi)由于金(jin)屬與(yu)氧(yang)化(hua)(hua)(hua)(hua)(hua)性(xing)(xing)物質(zhi)(zhi)作用(yong)，作用(yong)時在金(jin)屬表(biao)面生成 一種非常(chang)薄的(de)、致(zhi)密(mi)的(de)、覆蓋性(xing)(xing)能良好的(de)、牢(lao)固地吸附(fu)在金(jin)屬 表(biao)面上(shang)的(de)鈍化(hua)(hua)(hua)(hua)(hua)膜。與(yu)傳(chuan)統(tong)的(de)物理封閉法相比，鈍化(hua)(hua)(hua)(hua)(hua)處理后具(ju)有絕(jue)-對不增加工(gong)件厚度和改變顏(yan)色的(de)特點、提(ti)高(gao)了產品的(de)精密(mi)度和附(fu)加值(zhi)，使操作更方便(bian)。

背膠(jiao)：背膠(jiao)是(shi)(shi)(shi)郵票(piao)的(de)(de)重(zhong)要特(te)征之一(yi)。機加(jia)(jia)(jia)工(gong)(gong)(gong)：車削(xue)加(jia)(jia)(jia)工(gong)(gong)(gong)、刨削(xue)加(jia)(jia)(jia)工(gong)(gong)(gong)、銑削(xue)加(jia)(jia)(jia)工(gong)(gong)(gong)、磨削(xue)加(jia)(jia)(jia)工(gong)(gong)(gong)，滾(gun)牙(ya)：牙(ya)使(shi)用兩個帶(dai)有(you)螺(luo)紋(wen)的(de)(de)棍子來擠壓(ya)被加(jia)(jia)(jia)工(gong)(gong)(gong)的(de)(de)工(gong)(gong)(gong)件，使(shi)零件表(biao)面被壓(ya)出螺(luo)紋(wen)。攻(gong)牙(ya)：攻(gong)牙(ya)就是(shi)(shi)(shi)板牙(ya)，是(shi)(shi)(shi)用來加(jia)(jia)(jia)工(gong)(gong)(gong)或修理外螺(luo)紋(wen)的(de)(de)，它的(de)(de)內部是(shi)(shi)(shi)有(you)螺(luo)紋(wen)的(de)(de)，可手工(gong)(gong)(gong)加(jia)(jia)(jia)工(gong)(gong)(gong)也可以用在(zai)套絲機上(shang)。電鍍(du)：電鍍(du)分為掛鍍(du)、滾(gun)鍍(du)、連(lian)續鍍(du)和刷(shua)鍍(du)等方式，主要與(yu)待鍍(du)件的(de)(de)尺寸和批量有(you)關。
