電火花小孔機工作(zuo)原理(li)及應用：

電(dian)(dian)(dian)火(huo)花小孔(kong)(kong)機(ji)其(qi)工(gong)作原理是利用連續上下垂直(zhi)運動動的細(xi)金(jin)屬銅(tong)(tong)管(稱(cheng)為電(dian)(dian)(dian)極絲)作電(dian)(dian)(dian)極，對工(gong)件進行脈(mo)沖火(huo)花放電(dian)(dian)(dian)蝕除金(jin)屬成型。與電(dian)(dian)(dian)火(huo)花線切割機(ji)床、成型機(ji)不同的是，進口電(dian)(dian)(dian)火(huo)花小孔(kong)(kong)機(ji)生(sheng)產，它電(dian)(dian)(dian)脈(mo)沖的電(dian)(dian)(dian)極是空心銅(tong)(tong)棒(bang)，介質從(cong)銅(tong)(tong)棒(bang)孔(kong)(kong)中間(jian)的細(xi)孔(kong)(kong)穿過，電(dian)(dian)(dian)火(huo)花小孔(kong)(kong)機(ji)公(gong)司，起冷卻和排屑(xie)作用。

電(dian)極與金屬間放電(dian)產(chan)生高溫腐蝕(shi)金屬達到穿孔(kong)的(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)，用于加工(gong)(gong)超硬鋼材、硬質合金、銅、鋁及任何可(ke)導電(dian)性(xing)物質的(de)(de)(de)(de)(de)細孔(kong)。小(xiao)可(ke)加工(gong)(gong)0.015mm的(de)(de)(de)(de)(de)小(xiao)孔(kong)，也可(ke)加工(gong)(gong)帶有錐度的(de)(de)(de)(de)(de)小(xiao)孔(kong)，被(bei)廣泛(fan)使用在精密模具加工(gong)(gong)中，一般(ban)被(bei)當作電(dian)火(huo)花(hua)線(xian)切割機(ji)床的(de)(de)(de)(de)(de)配(pei)套設備，用于電(dian)火(huo)花(hua)線(xian)切割加工(gong)(gong)的(de)(de)(de)(de)(de)穿絲(si)孔(kong)、化纖(xian)噴(pen)絲(si)頭、噴(pen)絲(si)板的(de)(de)(de)(de)(de)噴(pen)絲(si)孔(kong)、濾板、篩板的(de)(de)(de)(de)(de)群孔(kong)、發動(dong)機(ji)葉(xie)片(pian)、缸體(ti)的(de)(de)(de)(de)(de)散熱孔(kong)、液壓、氣(qi)動(dong)閥體(ti)的(de)(de)(de)(de)(de)油(you)路(lu)、氣(qi)路(lu)孔(kong)等(deng)。

電火花小孔機的加(jia)工不(bu)穩定

1、檢查工件和電(dian)極(ji)裝夾是否可(ke)靠。

2、加(jia)工電壓無(wu)法調節，或(huo)者短(duan)路(lu)或(huo)者開路(lu)，伺(si)服系統可能有故障。

3、放電線(xian)是否(fou)連接可靠。

4、電(dian)(dian)極(ji)質量不(bu)高或(huo)工件材質有夾渣，銷售(shou)電(dian)(dian)火花小孔(kong)機公(gong)司，造成(cheng)電(dian)(dian)極(ji)i端(duan)部(bu)損耗不(bu)均勻(yun)，從(cong)而出現電(dian)(dian)極(ji)斜(xie)偏，可截去斜(xie)偏部(bu)分(fen)同(tong)時要用較好(hao)的電(dian)(dian)極(ji)和(he)工件材料。
