金(jin)(jin)屬(shu)(shu)因為強度高、質量輕、耐腐蝕性好、易(yi)加(jia)工而廣泛運用于產(chan)品(pin)的(de)外殼上。而金(jin)(jin)屬(shu)(shu)外殼在(zai)(zai)日(ri)常(chang)(chang)生活中是需要注(zhu)意保(bao)養和維護的(de)。金(jin)(jin)屬(shu)(shu)外殼的(de)保(bao)養方法：用完量具后(hou)，淮南金(jin)(jin)屬(shu)(shu)外殼加(jia)工，要擦干(gan)凈表面污漬(zi)、鋁(lv)(lv)屑，松(song)開(kai)緊固裝(zhuang)置，當(dang)長期（1個月以上）不用時，在(zai)(zai)測(ce)量面要涂防銹油(you)。鋁(lv)(lv)：通常(chang)(chang)一款比較厚(hou)的(de)鋁(lv)(lv)合(he)(he)金(jin)(jin)機箱，或(huo)者(zhe)鋁(lv)(lv)型材機箱，進行(xing)拉絲(si)氧化(hua)處理是比較適合(he)(he)的(de)，拉絲(si)氧化(hua)鋁(lv)(lv)板(ban)是反(fan)復用砂(sha)紙(zhi)將鋁(lv)(lv)板(ban)刮(gua)出(chu)線條的(de)制造過程(cheng)。

鍍鋅(xin)鋼板在(zai)靜電作用下，粉(fen)末會均勻的(de)(de)吸附于工(gong)(gong)(gong)(gong)件(jian)表面，形(xing)成粉(fen)狀的(de)(de)涂層(ceng)；粉(fen)狀涂層(ceng)經過高溫(wen)(wen)烘烤流(liu)平固化，變成效(xiao)(xiao)果各異（粉(fen)末涂料的(de)(de)不同(tong)種類效(xiao)(xiao)果）的(de)(de)終(zhong)涂層(ceng)。金屬外殼(ke)加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝學中，與(yu)熱(re)加(jia)工(gong)(gong)(gong)(gong)相對(dui)應，機(ji)箱(xiang)金屬外殼(ke)加(jia)工(gong)(gong)(gong)(gong)，冷(leng)加(jia)工(gong)(gong)(gong)(gong)則(ze)指在(zai)低于再(zai)結晶溫(wen)(wen)度(du)下使金屬產生塑性(xing)變形(xing)的(de)(de)加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝，如冷(leng)軋、冷(leng)拔(ba)、冷(leng)鍛(duan)、沖壓(ya)(ya)、冷(leng)擠壓(ya)(ya)等(deng)。鈑金機(ji)箱(xiang)外殼(ke)加(jia)工(gong)(gong)(gong)(gong)材料準(zhun)備(bei)(bei)：在(zai)我(wo)們準(zhun)備(bei)(bei)操作之前(qian)，一定要將需(xu)要的(de)(de)設(she)備(bei)(bei)準(zhun)備(bei)(bei)就緒，就是我(wo)們所使用的(de)(de)工(gong)(gong)(gong)(gong)具，比如游標卡尺、千分尺、鋼帶(dai)量具和針頭等(deng)。

冷(leng)加工(gong)(gong)(gong)(gong)變形抗力大，在(zai)使(shi)金(jin)屬(shu)成(cheng)形的(de)(de)同時，可(ke)以利用加工(gong)(gong)(gong)(gong)硬化(hua)提高工(gong)(gong)(gong)(gong)件(jian)的(de)(de)硬度(du)(du)和(he)強度(du)(du)，但會(hui)使(shi)塑(su)性降低(di)。冷(leng)加工(gong)(gong)(gong)(gong)適于(yu)加工(gong)(gong)(gong)(gong)截面(mian)尺寸(cun)小，金(jin)屬(shu)外(wai)(wai)殼(ke)(ke)加工(gong)(gong)(gong)(gong)中心(xin)，加工(gong)(gong)(gong)(gong)尺寸(cun)和(he)表(biao)面(mian)粗糙度(du)(du)要求較高的(de)(de)金(jin)屬(shu)零件(jian)。該如何保養金(jin)屬(shu)外(wai)(wai)殼(ke)(ke)：當工(gong)(gong)(gong)(gong)件(jian)表(biao)面(mian)有毛刺(ci)時，金(jin)屬(shu)外(wai)(wai)殼(ke)(ke)加工(gong)(gong)(gong)(gong)定制(zhi)，一(yi)定要去凈毛刺(ci)，再進(jin)行測(ce)(ce)量(liang)，否則會(hui)使(shi)量(liang)具磨損，并且(qie)還(huan)會(hui)影響(xiang)測(ce)(ce)量(liang)結果的(de)(de)準確性。靜電噴塑(su)的(de)(de)方(fang)式同樣可(ke)以用于(yu)普通的(de)(de)薄板(ban)鋁合金(jin)機(ji)箱，相對于(yu)氧化(hua)來說，這(zhe)種(zhong)表(biao)面(mian)處(chu)理方(fang)式要更實(shi)惠一(yi)些。
