一、火花機是干什么用的

火花機，又稱(cheng)電(dian)(dian)火(huo)花機(ji)(ji)，是(shi)利用(yong)浸在(zai)工(gong)(gong)作(zuo)液中的兩(liang)極間脈沖放電(dian)(dian)時產(chan)生的電(dian)(dian)蝕作(zuo)用(yong)蝕除導電(dian)(dian)材料的特種(zhong)加(jia)(jia)工(gong)(gong)方(fang)法，又稱(cheng)放電(dian)(dian)加(jia)(jia)工(gong)(gong)或電(dian)(dian)蝕加(jia)(jia)工(gong)(gong)，英文簡稱(cheng)EDM。火(huo)花機(ji)(ji)是(shi)一種(zhong)機(ji)(ji)械加(jia)(jia)工(gong)(gong)設(she)備，主要用(yong)于電(dian)(dian)火(huo)花機(ji)(ji)加(jia)(jia)工(gong)(gong)，廣泛應用(yong)在(zai)各種(zhong)金屬模具、機(ji)(ji)械設(she)備的制造中。

二、火花機的作用與用途

火花(hua)機(ji)(ji)的主要作用(yong)是利用(yong)火花(hua)放(fang)電(dian)(dian)(dian)時產生(sheng)的電(dian)(dian)(dian)蝕(shi)作用(yong)蝕(shi)除導電(dian)(dian)(dian)材料，從(cong)而實現對各種(zhong)導電(dian)(dian)(dian)材料的加工(gong)，如硬質合(he)金(jin)(jin)和(he)淬火鋼(gang)等。它(ta)能(neng)夠加工(gong)出具有(you)復雜形狀的型(xing)孔和(he)型(xing)腔的模具和(he)零件，同時也(ye)可以加工(gong)深細(xi)孔、異形孔、深槽、窄縫(feng)和(he)切割薄(bo)片等。此外(wai)，火花(hua)機(ji)(ji)還能(neng)夠加工(gong)各種(zhong)成形刀具、樣板和(he)螺紋環(huan)規等工(gong)具。火花(hua)機(ji)(ji)的應用(yong)范(fan)圍(wei)非常廣泛，包(bao)括五金(jin)(jin)廠(chang)、模具廠(chang)、電(dian)(dian)(dian)子廠(chang)、軍(jun)工(gong)、汽車模具廠(chang)、塑膠金(jin)(jin)屬(shu)等。

電火花(hua)加(jia)(jia)工(gong)(gong)(gong)可以加(jia)(jia)工(gong)(gong)(gong)高硬度、高韌性、高強度的(de)(de)模具材(cai)(cai)料，不(bu)(bu)同的(de)(de)工(gong)(gong)(gong)件材(cai)(cai)料還(huan)有不(bu)(bu)同機型的(de)(de)火花(hua)機適配加(jia)(jia)工(gong)(gong)(gong)。電火花(hua)加(jia)(jia)工(gong)(gong)(gong)還(huan)可以加(jia)(jia)工(gong)(gong)(gong)高溫合金等難(nan)加(jia)(jia)工(gong)(gong)(gong)材(cai)(cai)料，主要(yao)應用在航(hang)空航(hang)天領域。

精度高的火花機還可以加工高精度、高表面質量的零部件，包括如螺紋、渦輪等復雜曲面、復雜型腔的加工。在汽車制造領域中，主要用于生產復雜的汽車零件和用于加工塑料件、鑄件、鍛件或沖壓件所使用的模具，也可以使用高精度的鏡面火花機。火花機對(dui)精小電子元(yuan)件(jian)以及醫療器械的制造也能夠保證最小誤差的高精密加工。
