中走(zou)絲線(xian)切割工(gong)作液的(de)作用與注意事項：

乳化液(ye)(ye)作為工(gong)(gong)(gong)作介質(zhi)對(dui)于極間通道內冷卻狀態的(de)改善、消電(dian)離并恢復絕緣狀態均有較大的(de)影(ying)響，并且工(gong)(gong)(gong)件愈高，運絲(si)(si)速(su)度(du)愈慢，特(te)種(zhong)鋼材放電(dian)切割(ge)機，電(dian)極絲(si)(si)在加工(gong)(gong)(gong)區域停留(liu)時(shi)間將愈長，斷(duan)絲(si)(si)的(de)機率自然就會增加。而乳化液(ye)(ye)在放電(dian)通道內分解成(cheng)膠體(ti)或顆粒狀物質(zhi)是一種(zhong)必然的(de)現象，高速(su)放電(dian)切割(ge)機，所以使用乳化液(ye)(ye)作為工(gong)(gong)(gong)作介質(zhi)必然大大限制切割(ge)工(gong)(gong)(gong)藝指標的(de)提高i。極間冷卻狀態的(de)惡化其直接的(de)結(jie)果(guo)將導致WEDM-HS必須以十(shi)分保守的(de)放電(dian)能(neng)量換取(qu)不斷(duan)絲(si)(si)的(de)加工(gong)(gong)(gong)情況。

電(dian)極(ji)絲(si)直(zhi)徑(jing)的(de)(de)選(xuan)(xuan)擇應根據工件厚(hou)度(du)和拐角(jiao)尺寸(cun)大(da)(da)小來選(xuan)(xuan)擇。若加(jia)工大(da)(da)厚(hou)度(du)工件或大(da)(da)電(dian)流切割(ge)時應選(xuan)(xuan)較(jiao)粗的(de)(de)電(dian)極(ji)絲(si)，若加(jia)工帶(dai)尖角(jiao)、窄縫的(de)(de)小零件宜選(xuan)(xuan)用較(jiao)細的(de)(de)電(dian)極(ji)絲(si)。

放電間隙的(de)大小(xiao)與加(jia)工(gong)條件參數有關，放電切(qie)割機圖片，可(ke)以通過查表(機床生產廠家(jia)提(ti)供的(de)加(jia)工(gong)條件參數表)再計算得到，- -般快速走絲線切(qie)割加(jia)工(gong)時，取單邊放電間隙△=0. 01~0. 02mm。 對于加(jia)工(gong)條件參數表中查不到的(de)加(jia)工(gong)情況(kuang)和加(jia)工(gong)精度要求很高的(de)情況(kuang)，可(ke)以通過切(qie)割--個正方

形試件后實測得到。

電火(huo)花線切割機床特點與(yu)優點

控(kong)(kong)制系(xi)統 中走(zou)絲線切割多采用工(gong)(gong)業PC機構成一體化(hua)(hua)(hua)的(de)編程控(kong)(kong)制系(xi)統，無錫放電(dian)(dian)切割機，結合(he)工(gong)(gong)藝數據庫，系(xi)統能提供佳加工(gong)(gong)條件，以(yi)達到(dao)高速加工(gong)(gong)、保證(zheng)質量、簡化(hua)(hua)(hua)操作的(de)目的(de)。例如，用戶在輸入加工(gong)(gong)條件（材料、厚度等(deng)）、工(gong)(gong)藝參數（表面(mian)粗(cu)糙度等(deng)）后，系(xi)統就可給出合(he)適的(de)電(dian)(dian)規準(zhun)（脈(mo)沖(chong)寬(kuan)度、脈(mo)沖(chong)間隔、空載(zai)電(dian)(dian)壓、加工(gong)(gong)電(dian)(dian)壓、加工(gong)(gong)電(dian)(dian)流等(deng)），以(yi)及(ji)伺服(fu)進給速度、電(dian)(dian)極絲運絲速度等(deng)進行各(ge)次(ci)加工(gong)(gong)，并在加工(gong)(gong)中作出適當反(fan)應。所以(yi)，控(kong)(kong)制系(xi)統需要脈(mo)沖(chong)電(dian)(dian)源、機床(chuang)(chuang)電(dian)(dian)氣系(xi)統的(de)密切配合(he)，也(ye)有把這類型(xing)機床(chuang)(chuang)稱為“智能化(hua)(hua)(hua)多速走(zou)絲線切割機床(chuang)(chuang)”的(de)。
