電火花(hua)小孔(kong)機(ji)(ji)其實是(shi)(shi)用來電加工(gong)(gong)的(de)，屬于電加工(gong)(gong)機(ji)(ji)床，講到機(ji)(ji)床，大家都應該(gai)知道這是(shi)(shi)個什么東西，例如我(wo)們手機(ji)(ji)需要(yao)生(sheng)產(chan)(chan)時，就(jiu)需要(yao)到機(ji)(ji)床，還(huan)有(you)汽車制造也是(shi)(shi)需要(yao)到機(ji)(ji)床，只是(shi)(shi)機(ji)(ji)床的(de)分工(gong)(gong)不一樣而已。尤其是(shi)(shi)一些(xie)微小的(de)零件(jian)，我(wo)們更加需要(yao)機(ji)(ji)床來制作這些(xie)，有(you)人曾說，產(chan)(chan)品(pin)好不好，關鍵是(shi)(shi)機(ji)(ji)床的(de)精密度夠不夠好。

　　工作原理(li)：利用(yong)連續移動的(de)細(xi)金屬絲(稱(cheng)為電極絲)作電(dian)極，對工件進行脈(mo)(mo)沖(chong)(chong)火(huo)花(hua)放電(dian)蝕除金屬、切割(ge)成(cheng)型。與電(dian)火(huo)花(hua)線切割(ge)機床、成(cheng)型機不同(tong)的(de)是，它電(dian)脈(mo)(mo)沖(chong)(chong)的(de)電(dian)極是空心銅(tong)(tong)棒(bang)。介質從銅(tong)(tong)棒(bang)孔穿(chuan)過(guo)與工件發生放電(dian)，腐蝕金屬達到穿(chuan)孔的(de)目的(de)，用于加(jia)工超硬(ying)鋼材、硬(ying)質合金、銅(tong)(tong)、鋁及任(ren)何可導電(dian)性(xing)物(wu)質的(de)細孔。

　　該加(jia)(jia)工技(ji)術隨著微(wei)(wei)機(ji)械(xie)、精(jing)(jing)密(mi)機(ji)械(xie)、光學儀(yi)器等領(ling)域的(de)(de)不(bu)斷拓展而(er)得到廣泛(fan)的(de)(de)關(guan)注。電(dian)(dian)(dian)火花微(wei)(wei)孔(kong)(kong)加(jia)(jia)工以其加(jia)(jia)工中受力小(xiao)、加(jia)(jia)工的(de)(de)孔(kong)(kong)徑和深度由調節電(dian)(dian)(dian)參數就可得到控(kong)制(zhi)等優(you)勢，使其在(zai)各國的(de)(de)研究(jiu)日益活(huo)躍。電(dian)(dian)(dian)火花小(xiao)孔(kong)(kong)機(ji)利用(yong)電(dian)(dian)(dian)火花放電(dian)(dian)(dian)原理(li)加(jia)(jia)工精(jing)(jing)密(mi)微(wei)(wei)孔(kong)(kong)。適合于加(jia)(jia)工各類噴嘴精(jing)(jing)密(mi)微(wei)(wei)孔(kong)(kong)、化纖紡絲板(ban)精(jing)(jing)密(mi)微(wei)(wei)孔(kong)(kong)等各類精(jing)(jing)密(mi)微(wei)(wei)孔(kong)(kong)。通過簡單電(dian)(dian)(dian)極數控(kong)組合，加(jia)(jia)工噴絲板(ban)不(bu)同的(de)(de)規格、形狀、孔(kong)(kong)型的(de)(de)微(wei)(wei)孔(kong)(kong)和噴絲板(ban)的(de)(de)各種異形微(wei)(wei)孔(kong)(kong)。
