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(shang)是工件(jian)，而刀具在(zai)刀架(jia)上(shang)，并在(zai)XZ平面內做直(zhi)線運(yun)動。

數控銑床主軸上(shang)是銑刀，而工(gong)(gong)(gong)(gong)件在(zai)工(gong)(gong)(gong)(gong)作臺上(shang)，銑床在(zai)工(gong)(gong)(gong)(gong)作時，工(gong)(gong)(gong)(gong)件裝在(zai)工(gong)(gong)(gong)(gong)作臺上(shang)或分度頭(tou)等(deng)附件上(shang)，銑刀旋轉為主運(yun)動(dong)，輔以工(gong)(gong)(gong)(gong)作臺或銑頭(tou)的(de)進(jin)給運(yun)動(dong)，工(gong)(gong)(gong)(gong)件即(ji)可獲得所(suo)需(xu)的(de)加工(gong)(gong)(gong)(gong)表面。由(you)于(yu)是多刀斷續切削(xue)，因而數控銑床的(de)生產率較(jiao)高。

2、用途不同

數控車(che)床加工(gong)(gong)的零(ling)件是旋轉體，譬如軸(zhou)、孔(kong)、退刀(dao)槽、內外螺紋等。在數控車(che)床上還(huan)可用鉆(zhan)頭、擴孔(kong)鉆(zhan)、鉸刀(dao)、絲錐、板牙和滾花(hua)工(gong)(gong)具(ju)等進行相應的加工(gong)(gong)。數控車(che)床主要(yao)用于加工(gong)(gong)軸(zhou)、盤、套和其他具(ju)有(you)回轉表面(mian)的工(gong)(gong)件。

數控銑(xian)(xian)床它可(ke)(ke)以(yi)加(jia)工(gong)平(ping)面(mian)(mian)(mian)、溝(gou)槽，也可(ke)(ke)以(yi)加(jia)工(gong)各種(zhong)曲面(mian)(mian)(mian)、齒輪(lun)等。數控銑(xian)(xian)床除(chu)能銑(xian)(xian)削平(ping)面(mian)(mian)(mian)、溝(gou)槽、輪(lun)齒、螺紋和花鍵軸外(wai)，還能加(jia)工(gong)比較復雜的型面(mian)(mian)(mian)，效率較刨床高，此外(wai)，還可(ke)(ke)用于對(dui)回轉體表面(mian)(mian)(mian)、內孔加(jia)工(gong)及進行切斷工(gong)作等。

總結(jie)：數控銑床是用(yong)銑刀對工件進行(xing)銑削加工的機(ji)床，數控車(che)床主要用(yong)車(che)刀對旋轉(zhuan)的工件進行(xing)車(che)削加工的機(ji)床，用(yong)戶應根據自(zi)己(ji)的實際情況來選(xuan)定適合自(zi)己(ji)的機(ji)床。

二、數控銑床和加工中心的區別

數(shu)(shu)(shu)控銑(xian)床(chuang)只(zhi)有(you)三軸，數(shu)(shu)(shu)控加工中(zhong)心可以是四軸、五(wu)軸聯(lian)動，一般(ban)數(shu)(shu)(shu)控銑(xian)床(chuang)都是3個坐標(biao)即X，Y，Z，加一個主軸。而加工中(zhong)心則(ze)主要指四座標(biao)以上的機床(chuang)，加工中(zhong)心能夠加工比(bi)普通數(shu)(shu)(shu)控銑(xian)床(chuang)加工更為(wei)復雜的型面。

加工中心多(duo)了個刀(dao)(dao)庫和換(huan)刀(dao)(dao)系(xi)統，而數控銑(xian)(xian)床沒(mei)有(you)(you)刀(dao)(dao)庫，加(jia)(jia)(jia)工過程中(zhong)(zhong)都是手動(dong)實(shi)現換(huan)刀(dao)(dao)。數控銑(xian)(xian)床一般用來銑(xian)(xian)比(bi)較(jiao)簡(jian)樸(pu)的表面(mian)，也可以銑(xian)(xian)比(bi)較(jiao)淺的孔。而加(jia)(jia)(jia)工中(zhong)(zhong)心本身帶有(you)(you)刀(dao)(dao)庫，由機械手自動(dong)換(huan)刀(dao)(dao)具。數控銑(xian)(xian)床配上(shang)刀(dao)(dao)庫就成加(jia)(jia)(jia)工中(zhong)(zhong)心了，一個刀(dao)(dao)庫可以放(fang)很多(duo)把刀(dao)(dao)，要看實(shi)際加(jia)(jia)(jia)工的工件類(lei)型(xing)有(you)(you)面(mian)銑(xian)(xian)刀(dao)(dao)、立銑(xian)(xian)刀(dao)(dao)、鍵槽(cao)銑(xian)(xian)刀(dao)(dao)、球(qiu)刀(dao)(dao)、鏜孔刀(dao)(dao)、螺紋刀(dao)(dao)等等，具有(you)(you)自動(dong)交換(huan)刀(dao)(dao)具的功能，通過在刀(dao)(dao)庫安裝(zhuang)不同用途的刀(dao)(dao)具，可在一次裝(zhuang)夾中(zhong)(zhong)通過自動(dong)換(huan)刀(dao)(dao)裝(zhuang)置改變主軸(zhou)上(shang)的加(jia)(jia)(jia)工刀(dao)(dao)具，實(shi)現鉆(zhan)、鏜、鉸、攻(gong)螺紋、切槽(cao)等多(duo)種加(jia)(jia)(jia)工功能，方(fang)便(bian)零件加(jia)(jia)(jia)工！

加(jia)工中心是帶(dai)有刀庫(ku)和自動(dong)換刀裝置的數(shu)控機床(chuang)(chuang)，它將數(shu)控銑(xian)床(chuang)(chuang)、數(shu)控鏜(tang)床(chuang)(chuang)、數(shu)控鉆床(chuang)(chuang)的功(gong)能(neng)組合在一起，功(gong)能(neng)強大。
