我們在操作中(zhong)走絲技術線切(qie)(qie)割時，為了避(bi)免(mian)一(yi)(yi)些人員和(he)資金的浪費(fei)，中(zhong)走絲線切(qie)(qie)割加工需(xu)要滿足(zu)哪(na)些條件才能正常運行？江蘇創為數控機床(chuang)有限公司(si)跟大家一(yi)(yi)起聊聊這(zhe)個話(hua)題。

1. 鉬絲與工件的(de)(de)被加工表(biao)面之間(jian)必須(xu)保(bao)持一定間(jian)隙(xi)，間(jian)隙(xi)的(de)(de)寬(kuan)度由工作電壓(ya)、加工量等(deng)加工條(tiao)件而定。 

2. 電(dian)(dian)(dian)(dian)(dian)火(huo)花線切割機(ji)床加工(gong)時(shi)，必(bi)須在有(you)(you)一(yi)定絕緣(yuan)性(xing)能(neng)的(de)(de)液(ye)體介(jie)質中進行(xing)，如(ru)煤油(you)、皂化油(you)、去(qu)離(li)子水等，要求教高(gao)絕緣(yuan)性(xing)是為(wei)了利于產(chan)生脈沖性(xing)的(de)(de)火(huo)花放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)，液(ye)體介(jie)質還有(you)(you)排(pai)除間(jian)隙(xi)內電(dian)(dian)(dian)(dian)(dian)蝕(shi)產(chan)物和冷(leng)卻(que)電(dian)(dian)(dian)(dian)(dian)極作(zuo)用(yong)。鉬絲和工(gong)件(jian)被加工(gong)表(biao)面之(zhi)間(jian)保持一(yi)定間(jian)隙(xi)，如(ru)果間(jian)隙(xi)過(guo)大，極間(jian)電(dian)(dian)(dian)(dian)(dian)壓不(bu)能(neng)擊穿(chuan)極間(jian)介(jie)質，則不(bu)能(neng)產(chan)生電(dian)(dian)(dian)(dian)(dian)火(huo)花放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)；如(ru)果間(jian)隙(xi)過(guo)小，則容易形(xing)成短路連接，也不(bu)能(neng)產(chan)生電(dian)(dian)(dian)(dian)(dian)火(huo)花放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)。 

3. 必須采(cai)用脈(mo)(mo)(mo)(mo)沖電(dian)(dian)源，即火花放電(dian)(dian)必須是脈(mo)(mo)(mo)(mo)沖性、間歇性，脈(mo)(mo)(mo)(mo)沖寬(kuan)度、to為脈(mo)(mo)(mo)(mo)沖間隔(ge)(ge)、tp為脈(mo)(mo)(mo)(mo)沖周期。在脈(mo)(mo)(mo)(mo)沖間隔(ge)(ge)內，使間隙介質消除(chu)電(dian)(dian)離，使下一個脈(mo)(mo)(mo)(mo)沖能(neng)在兩極間擊穿放電(dian)(dian)。
