電火花(hua)中走絲切(qie)(qie)開(kai)機主要(yao)是使(shi)用電極(ji)(ji)絲對鈑金等金屬(shu)進行(xing)切(qie)(qie)開(kai)，在切(qie)(qie)開(kai)時，電極(ji)(ji)絲會迅速升到(dao)8000~12000度，此時兩(liang)導體(ti)外(wai)表(biao)瞬間(jian)熔化一些資料，到(dao)達切(qie)(qie)開(kai)的目(mu)的。為了電極(ji)(ji)絲不(bu)斷(duan)裂，該(gai)如何冷卻？

電極絲能(neng)夠通過特(te)域冷(leng)水機，冷(leng)卻電火花切開機的工作液到達(da)冷(leng)卻作用(yong)。

像咱們特域的(de)斯洛文尼亞客戶就是要(yao)冷卻電火花EDM切開(kai)(kai)機(ji)的(de)，他們的(de)切開(kai)(kai)機(ji)發(fa)熱(re)量到達(da)7KW~10KW，需要(yao)一個完整水冷系(xi)統進(jin)行冷卻，要(yao)求(qiu)水溫堅持(chi)在20~21℃。這(zhe)種情況，中走(zou)絲線切開(kai)(kai)機(ji)由機(ji)床本體(ti)，脈(mo)沖電源，微機(ji)操控設備，工作液循環系(xi)統組成(cheng)。

中走絲(si)(si)線(xian)(xian)切開(kai)機(ji)本(ben)體由(you)機(ji)床本(ben)體由(you)床身、運(yun)絲(si)(si)組織(zhi)、工(gong)作(zuo)(zuo)(zuo)(zuo)臺(tai)(tai)和(he)絲(si)(si)架(jia)(jia)組成(cheng)。床身：用(yong)于支(zhi)撐和(he)連接(jie)(jie)工(gong)作(zuo)(zuo)(zuo)(zuo)臺(tai)(tai)、運(yun)絲(si)(si)組織(zhi)等部(bu)件，內(nei)部(bu)安放機(ji)床電(dian)(dian)器(qi)和(he)工(gong)作(zuo)(zuo)(zuo)(zuo)液(ye)循環系統。運(yun)絲(si)(si)組織(zhi)：電(dian)(dian)動(dong)(dong)機(ji)帶動(dong)(dong)儲絲(si)(si)筒替換作(zuo)(zuo)(zuo)(zuo)正、反向(xiang)滾動(dong)(dong)，通過線(xian)(xian)架(jia)(jia)導輪(lun)將(jiang)旋轉(zhuan)運(yun)動(dong)(dong)轉(zhuan)變為往復直線(xian)(xian)運(yun)動(dong)(dong)。工(gong)作(zuo)(zuo)(zuo)(zuo)臺(tai)(tai)：工(gong)作(zuo)(zuo)(zuo)(zuo)臺(tai)(tai)分為上下(xia)兩(liang)(liang)層，別離與X、Y向(xiang)絲(si)(si)杠相連，由(you)兩(liang)(liang)個步進(jin)電(dian)(dian)機(ji)別離驅(qu)動(dong)(dong)。步進(jin)電(dian)(dian)機(ji)每(mei)接(jie)(jie)受(shou)到一個電(dian)(dian)脈沖信(xin)號，就旋轉(zhuan)一步距角，使(shi)工(gong)作(zuo)(zuo)(zuo)(zuo)臺(tai)(tai)在(zai)相應的方向(xiang)上移動(dong)(dong)0.001mm。絲(si)(si)架(jia)(jia)：用(yong)來支(zhi)撐電(dian)(dian)極絲(si)(si)，并(bing)使(shi)電(dian)(dian)極絲(si)(si)工(gong)作(zuo)(zuo)(zuo)(zuo)部(bu)分與工(gong)作(zuo)(zuo)(zuo)(zuo)臺(tai)(tai)平面堅持必定(ding)的幾許(xu)角度。

電(dian)(dian)(dian)(dian)火(huo)花(hua)機(ji)是使用浸在工(gong)(gong)作(zuo)(zuo)液中的(de)兩極間脈沖放(fang)電(dian)(dian)(dian)(dian)時產(chan)生(sheng)的(de)電(dian)(dian)(dian)(dian)蝕(shi)作(zuo)(zuo)用蝕(shi)除導電(dian)(dian)(dian)(dian)資料的(de)特種(zhong)加工(gong)(gong)辦法，又稱放(fang)電(dian)(dian)(dian)(dian)加工(gong)(gong)或電(dian)(dian)(dian)(dian)蝕(shi)加工(gong)(gong)。電(dian)(dian)(dian)(dian)火(huo)花(hua)加工(gong)(gong)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)是指(zhi)脈沖電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路輸出的(de)直(zhi)流電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，它(ta)有(you)高壓(ya)(ya)(ya)(ya)直(zhi)流電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)和低壓(ya)(ya)(ya)(ya)直(zhi)流電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)兩種(zhong)，因而(er)由火(huo)花(hua)加工(gong)(gong)原理可知加工(gong)(gong)過程中，首要加高壓(ya)(ya)(ya)(ya)直(zhi)流電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，構成放(fang)電(dian)(dian)(dian)(dian)通道；在放(fang)電(dian)(dian)(dian)(dian)通道構成后，中走(zou)絲(si)則由低壓(ya)(ya)(ya)(ya)直(zhi)流電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)來維持放(fang)電(dian)(dian)(dian)(dian)通道。機(ji)床操控框上(shang)的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)表指(zhi)示加工(gong)(gong)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)的(de)幅值的(de)變(bian)化。
