眾所周知,光纖激光切割機是(shi)站在(zai)(zai)巨(ju)人肩膀上的(de)進步(bu),它先是(shi)在(zai)(zai)眾多發達國家興起,并且(qie)顯著地(di)帶(dai)動了其相關制造產業(ye)的(de)快速發展,中(zhong)國近年來開始迎頭趕超,并且(qie)已(yi)經(jing)在(zai)(zai)光(guang)纖(xian)激光(guang)切割機(ji)領(ling)域實現后來居上。這一成果使(shi)得中(zhong)國縮短了高(gao)端制造與國外高(gao)端裝備(bei)制造差距,甚至有可能使(shi)得中(zhong)國高(gao)端裝備(bei)制造趕上國外高(gao)端裝備(bei)制造技術的(de)步(bu)伐,光(guang)纖(xian)激光(guang)切割機(ji)助力中(zhong)國制造業(ye)實現跨越式發展。光(guang)纖(xian)激光(guang)切割機(ji)近些年來在(zai)(zai)鈑(ban)金加工行業(ye)可謂是(shi)異(yi)軍突起,激光(guang)
切割產業(ye)作(zuo)為(wei)鈑金行業(ye)的一支主力軍。
傳統(tong)的鈑金(jin)加工(gong)工(gong)藝(yi):剪切(qie)-沖-折彎(wan)-焊接流程或者火焰等離子切(qie)割-折彎(wan)-焊接工(gong)藝(yi)。在多品(pin)種、小批(pi)量、定制化、高質量、短交貨(huo)期的訂單(dan)面前,它有著明顯(xian)的不足:
①(數(shu)控)剪床由于其主要(yao)是直線裁剪,不(bu)適(shi)用(yong)于復雜的鈑(ban)金(jin)加工;
②(數(shu)控/磚塔)沖床對厚度在1.5mm以上的鋼板切割有限制,并且表面質(zhi)量(liang)不好,成本高、噪音(yin)大,不利于(yu)環保;
③ 火焰切割作為最(zui)初的傳統(tong)切割方式(shi),在切割時熱變形(xing)大、割縫(feng)寬,浪費材料(liao),加工(gong)速度慢(man),只適合粗加工(gong);
④高壓水切割加工速(su)度慢,造成污染嚴重(zhong),消耗成本高。

新型鈑(ban)金激光切割(ge)機(ji)工藝(yi)的優點有:
①激光切(qie)割(ge)柔性化程度高(gao),切(qie)割(ge)速(su)度快,生產效率高(gao),產品(pin)生產周期短,不管是(shi)簡(jian)單還是(shi)復雜(za)零件,都可以用激光實現一次(ci)快速(su)成形切(qie)割(ge);
②切(qie)(qie)縫窄、切(qie)(qie)割質量好、自動化(hua)程度高,操作簡(jian)便,勞動強度低,沒有污染;
③可實現切割自動排樣、套(tao)料,提高了材料利用率,無刀具(ju)磨損,材料適(shi)應(ying)性好;
④生產成本低,經(jing)濟效益好。
