石墨(mo)電(dian)極(ji)加工(gong)的分類和機(ji)床加工(gong)辦法(fa)
    石(shi)墨(mo)電極(ji)加工(gong)分為(wei)電(dian)極(ji)本體(ti)和接頭(tou)兩個獨(du)立(li)加(jia)工(gong)件。石(shi)墨(mo)電(dian)極(ji)本體(ti)加工(gong)包(bao)括車(che)外圓（也(ye)稱“扒荒”或“拉(la)荒”）、端(duan)面(mian)加(jia)工(gong)（平端(duan)面(mian)及鏜(tang)接頭(tou)孔(kong)）、在(zai)接頭(tou)孔(kong)內(nei)石(shi)墨電極(ji)加工(gong)連(lian)接用(yong)螺紋（母(mu)螺(luo)紋）和(he)切削(xue)半扣等(deng)三項單(dan)元(yuan)操(cao)作(zuo)。接頭(tou)加工(gong)包(bao)括車(che)外圓、在(zai)外圓外表(biao)加(jia)工(gong)公(gong)螺紋(wen)、切(qie)斷(duan)後對(dui)兩個端(duan)面(mian)磨平(ping)及加(jia)工(gong)半扣等(deng)三項單(dan)元(yuan)操(cao)作(zuo)。石(shi)墨電極(ji)加工(gong)辦法(fa)分為(wei)運(yun)用(yong)壹般車(che)床加工(gong)和運(yun)用(yong)專門規劃(hua)的組(zu)合(he)機(ji)床加工(gong)兩種(zhong)類型。
用(yong)壹般車(che)床進行(xing)石墨電(dian)極(ji)加工(gong)
    石墨(mo)電(dian)極(ji)本體(ti)加工(gong)壹般(ban)由(you)三(san)臺車床組(zu)成(cheng)壹條流水(shui)作業(ye)線(xian)，第壹(yi)臺車床承(cheng)當外圓加(jia)工(gong)，第二臺車床承(cheng)當加工(gong)端(duan)面(mian)及鏜(tang)接頭(tou)孔(kong)，第三(san)臺車床則專(zhuan)門加工(gong)接頭(tou)孔(kong)內(nei)的(de)母螺紋(wen)。接頭(tou)加工(gong)壹般(ban)由(you)別的兩(liang)臺車床完成(cheng)，第壹(yi)臺車床承(cheng)當外圓加(jia)工(gong)及在(zai)外表(biao)銑(xi)出公(gong)螺紋(wen)，再按(an)規則長(chang)度(du)切(qie)壹(yi)深槽(cao)（不斷開(kai)），第二臺車床加工(gong)斷開(kai)後接頭(tou)的兩(liang)個端(duan)面(mian)及半扣（小(xiao)標(biao)準產(chan)品(pin)這(zhe)壹(yi)工(gong)序可(ke)用(yong)砂輪機(ji)進行(xing)）。接頭(tou)加工(gong)時的(de)車(che)外(wai)圓及銑(xi)公(gong)螺紋(wen)與電(dian)極(ji)本體(ti)加工(gong)根本相(xiang)同(tong)，大(da)標(biao)準接頭(tou)的平(ping)端(duan)面(mian)及加(jia)工(gong)半扣在(zai)另壹臺車床上進行(xing)。
