一、數控銑床和數控車床的區別
1、工作原理不同
數控車床主(zhu)軸上是工件,而(er)刀(dao)具在(zai)刀(dao)架上,并在(zai)XZ平面(mian)內做直線(xian)運動(dong)。
數控銑床主軸上(shang)是銑(xian)(xian)刀(dao),而(er)工(gong)(gong)(gong)(gong)(gong)件(jian)在工(gong)(gong)(gong)(gong)(gong)作(zuo)臺上(shang),銑(xian)(xian)床在工(gong)(gong)(gong)(gong)(gong)作(zuo)時,工(gong)(gong)(gong)(gong)(gong)件(jian)裝在工(gong)(gong)(gong)(gong)(gong)作(zuo)臺上(shang)或(huo)分度頭(tou)等附件(jian)上(shang),銑(xian)(xian)刀(dao)旋轉為主運(yun)(yun)動(dong),輔以工(gong)(gong)(gong)(gong)(gong)作(zuo)臺或(huo)銑(xian)(xian)頭(tou)的進(jin)給運(yun)(yun)動(dong),工(gong)(gong)(gong)(gong)(gong)件(jian)即可獲得所需的加工(gong)(gong)(gong)(gong)(gong)表(biao)面。由于是多(duo)刀(dao)斷(duan)續(xu)切削,因而(er)數控銑(xian)(xian)床的生產率較高。
2、用途不同
數(shu)控(kong)車(che)床加工(gong)的零件(jian)是旋轉(zhuan)(zhuan)體,譬如(ru)軸(zhou)、孔(kong)、退刀(dao)槽、內外螺紋等。在數(shu)控(kong)車(che)床上還可(ke)用鉆頭、擴孔(kong)鉆、鉸刀(dao)、絲錐、板牙和滾(gun)花工(gong)具(ju)等進行相(xiang)應的加工(gong)。數(shu)控(kong)車(che)床主要用于加工(gong)軸(zhou)、盤、套和其(qi)他具(ju)有(you)回轉(zhuan)(zhuan)表面的工(gong)件(jian)。
數(shu)控(kong)銑(xian)(xian)床(chuang)(chuang)它(ta)可以(yi)加(jia)(jia)工平(ping)面(mian)、溝槽,也可以(yi)加(jia)(jia)工各(ge)種曲(qu)面(mian)、齒輪(lun)等(deng)。數(shu)控(kong)銑(xian)(xian)床(chuang)(chuang)除(chu)能銑(xian)(xian)削平(ping)面(mian)、溝槽、輪(lun)齒、螺(luo)紋(wen)和花(hua)鍵(jian)軸外,還(huan)能加(jia)(jia)工比較復(fu)雜的型面(mian),效率(lv)較刨床(chuang)(chuang)高(gao),此外,還(huan)可用于對回(hui)轉(zhuan)體(ti)表(biao)面(mian)、內孔加(jia)(jia)工及進(jin)行切斷工作等(deng)。
總結:數(shu)控(kong)銑(xian)(xian)床(chuang)(chuang)是用銑(xian)(xian)刀對工(gong)件進(jin)行(xing)銑(xian)(xian)削加工(gong)的(de)(de)(de)機床(chuang)(chuang),數(shu)控(kong)車床(chuang)(chuang)主要用車刀對旋轉的(de)(de)(de)工(gong)件進(jin)行(xing)車削加工(gong)的(de)(de)(de)機床(chuang)(chuang),用戶應(ying)根據自己(ji)(ji)的(de)(de)(de)實際情況來選定適(shi)合自己(ji)(ji)的(de)(de)(de)機床(chuang)(chuang)。
二、數控銑床和加工中心的區別
數(shu)(shu)控(kong)銑(xian)床只有(you)三(san)軸(zhou),數(shu)(shu)控(kong)加(jia)工(gong)中心(xin)可以是四軸(zhou)、五軸(zhou)聯動,一(yi)(yi)般數(shu)(shu)控(kong)銑(xian)床都是3個(ge)坐標即X,Y,Z,加(jia)一(yi)(yi)個(ge)主(zhu)軸(zhou)。而(er)加(jia)工(gong)中心(xin)則(ze)主(zhu)要指四座標以上的機床,加(jia)工(gong)中心(xin)能夠(gou)加(jia)工(gong)比普(pu)通數(shu)(shu)控(kong)銑(xian)床加(jia)工(gong)更為復雜的型面。
加工中心多(duo)了個(ge)刀(dao)庫(ku)(ku)和(he)換(huan)刀(dao)系(xi)統,而數(shu)控銑(xian)(xian)(xian)床(chuang)沒有(you)刀(dao)庫(ku)(ku),加(jia)工過程中都是手動(dong)實現換(huan)刀(dao)。數(shu)控銑(xian)(xian)(xian)床(chuang)一(yi)般(ban)用(yong)來銑(xian)(xian)(xian)比較(jiao)簡(jian)樸(pu)的(de)(de)表(biao)面,也可以銑(xian)(xian)(xian)比較(jiao)淺(qian)的(de)(de)孔。而加(jia)工中心本(ben)身帶有(you)刀(dao)庫(ku)(ku),由機械手自動(dong)換(huan)刀(dao)具(ju)。數(shu)控銑(xian)(xian)(xian)床(chuang)配上刀(dao)庫(ku)(ku)就成加(jia)工中心了,一(yi)個(ge)刀(dao)庫(ku)(ku)可以放很(hen)多(duo)把刀(dao),要看實際加(jia)工的(de)(de)工件(jian)類型(xing)有(you)面銑(xian)(xian)(xian)刀(dao)、立銑(xian)(xian)(xian)刀(dao)、鍵槽銑(xian)(xian)(xian)刀(dao)、球(qiu)刀(dao)、鏜(tang)孔刀(dao)、螺紋刀(dao)等等,具(ju)有(you)自動(dong)交換(huan)刀(dao)具(ju)的(de)(de)功能(neng),通過在(zai)(zai)刀(dao)庫(ku)(ku)安(an)裝(zhuang)不同用(yong)途(tu)的(de)(de)刀(dao)具(ju),可在(zai)(zai)一(yi)次(ci)裝(zhuang)夾(jia)中通過自動(dong)換(huan)刀(dao)裝(zhuang)置改變主軸上的(de)(de)加(jia)工刀(dao)具(ju),實現鉆、鏜(tang)、鉸(jiao)、攻螺紋、切槽等多(duo)種加(jia)工功能(neng),方便零件(jian)加(jia)工!
加工中心是帶有刀(dao)庫和自(zi)動換刀(dao)裝置的(de)數(shu)(shu)控(kong)機床,它將數(shu)(shu)控(kong)銑床、數(shu)(shu)控(kong)鏜床、數(shu)(shu)控(kong)鉆床的(de)功能(neng)組(zu)合在一起(qi),功能(neng)強(qiang)大(da)。
