縱覽中國鈑(ban)金(jin)(jin)加(jia)工(gong)(gong)(gong)(gong)技(ji)能，原本就是(shi)鈑(ban)金(jin)(jin)加(jia)工(gong)(gong)(gong)(gong)設(she)(she)備(bei)(bei)不斷創新，持續領(ling)i跑(pao)的(de)(de)演(yan)變史，常(chang)言道，空調鈑(ban)金(jin)(jin)件(jian)，“工(gong)(gong)(gong)(gong)欲(yu)善(shan)其(qi)時，工(gong)(gong)(gong)(gong)欲(yu)善(shan)其(qi)事”，而(er)中國的(de)(de)鈑(ban)金(jin)(jin)加(jia)工(gong)(gong)(gong)(gong)業也證明了這些觀點(dian)呢。現如今的(de)(de)鈑(ban)金(jin)(jin)加(jia)工(gong)(gong)(gong)(gong)與(yu)傳(chuan)統(tong)(tong)的(de)(de)的(de)(de)鈑(ban)金(jin)(jin)加(jia)工(gong)(gong)(gong)(gong)擁有質的(de)(de)騰越，傳(chuan)統(tong)(tong)式的(de)(de)鈑(ban)金(jin)(jin)加(jia)工(gong)(gong)(gong)(gong)手(shou)藝(yi)多憑借技(ji)藝(yi)手(shou)藝(yi)，嘉興鈑(ban)金(jin)(jin)件(jian)，而(er)現今的(de)(de)鈑(ban)金(jin)(jin)加(jia)工(gong)(gong)(gong)(gong)手(shou)藝(yi)則(ze)要以數(shu)控(kong)機床(chuang)鈑(ban)金(jin)(jin)加(jia)工(gong)(gong)(gong)(gong)設(she)(she)備(bei)(bei)為核i心(xin)，配置各種各樣大中型鈑(ban)金(jin)(jin)加(jia)工(gong)(gong)(gong)(gong)設(she)(she)備(bei)(bei)。這二者已經沒有可比性了呢。

鈑金機殼(ke)定制(zhi)沖(chong)壓時有(you)(you)什么特點？與(yu)鑄鍛(duan)件(jian)(jian)相(xiang)比，冰(bing)箱鈑金件(jian)(jian)，沖(chong)壓件(jian)(jian)薄、均勻、輕便(bian)、堅固。沖(chong)壓可生產其他(ta)方法難以(yi)制(zhi)造(zao)的(de)帶(dai)有(you)(you)加(jia)強筋(jin)、加(jia)強筋(jin)、波(bo)紋或(huo)翻(fan)邊(bian)的(de)工(gong)件(jian)(jian)。

（1）沖(chong)(chong)(chong)壓(ya)(ya)(ya)加工生產效率i高，操作方便，易于機(ji)械化和(he)自動化。這是因為(wei)沖(chong)(chong)(chong)壓(ya)(ya)(ya)依賴于沖(chong)(chong)(chong)壓(ya)(ya)(ya)模具和(he)沖(chong)(chong)(chong)壓(ya)(ya)(ya)設(she)備來完成加工。普通壓(ya)(ya)(ya)力機(ji)的行程次(ci)數可(ke)以達到(dao)每(mei)(mei)分(fen)鐘幾十次(ci)，高速壓(ya)(ya)(ya)力可(ke)以達到(dao)每(mei)(mei)分(fen)鐘數百(bai)甚至數千(qian)次(ci)，每(mei)(mei)個(ge)沖(chong)(chong)(chong)壓(ya)(ya)(ya)行程可(ke)以得到(dao)一個(ge)沖(chong)(chong)(chong)壓(ya)(ya)(ya)件。

（2）就像用兩顆豌豆來保(bao)證沖壓件的表面質量一樣，模具(ju)壽命一般比沖壓模長(chang)。沖壓質量穩定，互換性好，具(ju)有相同的特點(dian)。

（3） 沖壓(ya)可(ke)以(yi)加工尺寸范圍大(da)、形狀(zhuang)復雜的零件(jian)(jian)，如鐘表的秒(miao)針、汽車(che)縱梁(liang)和覆(fu)蓋(gai)件(jian)(jian)等(deng)。結合材(cai)料在沖壓(ya)過程(cheng)中的冷變形硬化效應，沖壓(ya)的強度(du)(du)和剛度(du)(du)都很高。

金(jin)屬切(qie)削(xue)是鈑(ban)金(jin)加(jia)工中(zhong)不可缺少的一(yi)道(dao)工序(xu)。下面(mian)，我(wo)們將列出幾代(dai)金(jin)屬切(qie)削(xue)工藝，并(bing)細分其優缺點，如下所示：

首先，精密鈑金件加(jia)工，線切割：它是在EDM穿(chuan)孔和成形的(de)基礎上發(fa)展(zhan)起來的(de)。

鉬(mu)絲蝕刻原理是特殊的金屬切(qie)割方法：

優點(dian)：精度高，初(chu)始(shi)設(she)備(bei)投入少(shao)，可以切(qie)割(ge)特殊形狀(zhuang)的(de)金(jin)屬。

缺(que)點：不(bu)易磨損，尤其是當不(bu)銹鋼等金屬硬度(du)高，切割(ge)速度(du)慢時，不(bu)適合(he)大規模(mo)加工。
