五金加工就(jiu)是(shi)將原材料(liao)(不銹鋼、銅料(liao)、鋁料(liao)、鐵料(liao))，用車(che)(che)床(chuang)、銑床(chuang)、鉆床(chuang)、磨床(chuang)、拋(pao)光等機械按客戶的圖紙或樣品加(jia)工成為(wei)各種零(ling)件，如(ru)：螺(luo)絲 、馬達軸(zhou)、模型(xing)車(che)(che)零(ling)件、移動(dong)電源外殼等。五(wu)(wu)金(jin)表(biao)面(mian)(mian)加(jia)工細分可(ke)分為(wei)：五(wu)(wu)金(jin)噴漆(qi)加(jia)工、電鍍、表(biao)面(mian)(mian)拋(pao)光加(jia)工、五(wu)(wu)金(jin)腐蝕加(jia)工等等。拋(pao)光：原理(li)是(shi)指(zhi)通過有規(gui)則溶解達到(dao)光亮平(ping)滑；方(fang)法：利用機械、化學或電化學的作用，使(shi)工件表(biao)面(mian)(mian)粗(cu)糙(cao)度降低，得以是(shi)五(wu)(wu)金(jin)加(jia)工獲得光亮、平(ping)整表(biao)面(mian)(mian)的加(jia)工方(fang)法。是(shi)利用拋(pao) 光工具和磨料(liao)顆粒或其他拋(pao)光介質(zhi)對工件表(biao)面(mian)(mian)進行的修(xiu)飾加(jia)工。

五金(jin)(jin)加(jia)(jia)工的(de)氧(yang)(yang)化(hua)(hua)(hua)(hua)(hua)分為(wei)鋁硬質氧(yang)(yang)化(hua)(hua)(hua)(hua)(hua)、壓鑄鋁氧(yang)(yang)化(hua)(hua)(hua)(hua)(hua)、彩(cai)色(se)氧(yang)(yang)化(hua)(hua)(hua)(hua)(hua)、鋁陽(yang)極氧(yang)(yang)化(hua)(hua)(hua)(hua)(hua)、本色(se)氧(yang)(yang)化(hua)(hua)(hua)(hua)(hua)等。鈍化(hua)(hua)(hua)(hua)(hua)：原理可(ke)以用(yong)薄膜理論來解釋，鈍化(hua)(hua)(hua)(hua)(hua)是由于金(jin)(jin)屬(shu)與氧(yang)(yang)化(hua)(hua)(hua)(hua)(hua)性物(wu)質作(zuo)用(yong)，作(zuo)用(yong)時在(zai)金(jin)(jin)屬(shu)表面生成 一種非常薄的(de)、致密的(de)、覆蓋性能良好的(de)、牢(lao)固地吸附(fu)(fu)在(zai)金(jin)(jin)屬(shu) 表面上的(de)鈍化(hua)(hua)(hua)(hua)(hua)膜。與傳統的(de)物(wu)理封閉法相比，鈍化(hua)(hua)(hua)(hua)(hua)處理后具有(you)絕-對不增加(jia)(jia)工件厚度(du)和改變(bian)顏色(se)的(de)特點、提(ti)高了產品的(de)精(jing)密度(du)和附(fu)(fu)加(jia)(jia)值，使操作(zuo)更(geng)方便。

背(bei)膠：背(bei)膠是(shi)郵(you)票(piao)的重(zhong)要特征之一(yi)。機加(jia)工(gong)(gong)(gong)：車(che)削(xue)(xue)加(jia)工(gong)(gong)(gong)、刨削(xue)(xue)加(jia)工(gong)(gong)(gong)、銑削(xue)(xue)加(jia)工(gong)(gong)(gong)、磨削(xue)(xue)加(jia)工(gong)(gong)(gong)，滾(gun)牙：牙使(shi)用兩(liang)個帶有螺(luo)紋(wen)的棍子來擠壓被加(jia)工(gong)(gong)(gong)的工(gong)(gong)(gong)件(jian)，使(shi)零件(jian)表面被壓出螺(luo)紋(wen)。攻(gong)牙：攻(gong)牙就是(shi)板牙，是(shi)用來加(jia)工(gong)(gong)(gong)或(huo)修(xiu)理外螺(luo)紋(wen)的，它的內部(bu)是(shi)有螺(luo)紋(wen)的，可手(shou)工(gong)(gong)(gong)加(jia)工(gong)(gong)(gong)也可以用在套絲(si)機上(shang)。電鍍(du)(du)：電鍍(du)(du)分為掛(gua)鍍(du)(du)、滾(gun)鍍(du)(du)、連(lian)續鍍(du)(du)和刷鍍(du)(du)等方式(shi)，主(zhu)要與待鍍(du)(du)件(jian)的尺(chi)寸和批量(liang)有關。
