一、數控銑床和數控車床的區別
1、工作原理不同
數控車床主軸上(shang)是工件,而刀具在(zai)刀架上(shang),并(bing)在(zai)XZ平面(mian)內(nei)做直線運動。
數控銑床主軸上(shang)(shang)(shang)是(shi)銑(xian)刀,而(er)(er)工(gong)(gong)(gong)件(jian)(jian)在(zai)(zai)工(gong)(gong)(gong)作(zuo)(zuo)臺上(shang)(shang)(shang),銑(xian)床(chuang)在(zai)(zai)工(gong)(gong)(gong)作(zuo)(zuo)時,工(gong)(gong)(gong)件(jian)(jian)裝在(zai)(zai)工(gong)(gong)(gong)作(zuo)(zuo)臺上(shang)(shang)(shang)或分(fen)度頭(tou)等附件(jian)(jian)上(shang)(shang)(shang),銑(xian)刀旋(xuan)轉為主運動,輔(fu)以工(gong)(gong)(gong)作(zuo)(zuo)臺或銑(xian)頭(tou)的進(jin)給(gei)運動,工(gong)(gong)(gong)件(jian)(jian)即可獲得所需的加工(gong)(gong)(gong)表面。由于(yu)是(shi)多刀斷續切削(xue),因而(er)(er)數控銑(xian)床(chuang)的生產率較高。
2、用途不同
數(shu)(shu)控車(che)床(chuang)加工(gong)的(de)零件(jian)是(shi)旋(xuan)轉體,譬(pi)如(ru)軸、孔、退(tui)刀槽、內外螺紋(wen)等。在數(shu)(shu)控車(che)床(chuang)上還(huan)可用鉆頭、擴孔鉆、鉸刀、絲錐、板牙(ya)和(he)滾(gun)花工(gong)具等進行(xing)相(xiang)應(ying)的(de)加工(gong)。數(shu)(shu)控車(che)床(chuang)主要用于(yu)加工(gong)軸、盤、套和(he)其他具有回轉表(biao)面的(de)工(gong)件(jian)。
數控銑(xian)床(chuang)(chuang)它可以(yi)加工(gong)平面(mian)(mian)(mian)、溝槽,也可以(yi)加工(gong)各種曲面(mian)(mian)(mian)、齒輪等。數控銑(xian)床(chuang)(chuang)除能(neng)銑(xian)削平面(mian)(mian)(mian)、溝槽、輪齒、螺紋和花鍵(jian)軸外,還(huan)(huan)能(neng)加工(gong)比較復雜的型面(mian)(mian)(mian),效(xiao)率較刨(bao)床(chuang)(chuang)高(gao),此外,還(huan)(huan)可用于對回(hui)轉體表(biao)面(mian)(mian)(mian)、內孔加工(gong)及(ji)進(jin)行切斷工(gong)作等。
總結:數控(kong)銑床是用(yong)銑刀對工件進(jin)行銑削加(jia)工的(de)(de)機床,數控(kong)車床主要用(yong)車刀對旋轉的(de)(de)工件進(jin)行車削加(jia)工的(de)(de)機床,用(yong)戶應根據自己的(de)(de)實際(ji)情況來選定適合自己的(de)(de)機床。
二、數控銑床和加工中心的區別
數控銑床只有三軸(zhou),數控加(jia)工(gong)中(zhong)心可以是(shi)四軸(zhou)、五軸(zhou)聯動(dong),一(yi)般數控銑床都是(shi)3個(ge)坐標(biao)即X,Y,Z,加(jia)一(yi)個(ge)主(zhu)軸(zhou)。而加(jia)工(gong)中(zhong)心則主(zhu)要指四座標(biao)以上(shang)的機床,加(jia)工(gong)中(zhong)心能夠加(jia)工(gong)比普通數控銑床加(jia)工(gong)更(geng)為復雜的型面。
加工中心多(duo)了個刀(dao)(dao)庫(ku)(ku)(ku)(ku)和換(huan)(huan)刀(dao)(dao)系統,而數控銑(xian)床(chuang)沒有(you)刀(dao)(dao)庫(ku)(ku)(ku)(ku),加工(gong)過程中(zhong)都是手動(dong)(dong)實現換(huan)(huan)刀(dao)(dao)。數控銑(xian)床(chuang)一般用來銑(xian)比較簡樸的表面,也可(ke)(ke)以銑(xian)比較淺的孔。而加工(gong)中(zhong)心本身帶有(you)刀(dao)(dao)庫(ku)(ku)(ku)(ku),由機械手自動(dong)(dong)換(huan)(huan)刀(dao)(dao)具(ju)。數控銑(xian)床(chuang)配上刀(dao)(dao)庫(ku)(ku)(ku)(ku)就(jiu)成加工(gong)中(zhong)心了,一個刀(dao)(dao)庫(ku)(ku)(ku)(ku)可(ke)(ke)以放很多(duo)把刀(dao)(dao),要看實際(ji)加工(gong)的工(gong)件類型(xing)有(you)面銑(xian)刀(dao)(dao)、立銑(xian)刀(dao)(dao)、鍵槽(cao)(cao)銑(xian)刀(dao)(dao)、球刀(dao)(dao)、鏜孔刀(dao)(dao)、螺紋刀(dao)(dao)等(deng)等(deng),具(ju)有(you)自動(dong)(dong)交(jiao)換(huan)(huan)刀(dao)(dao)具(ju)的功(gong)(gong)能(neng),通過在(zai)(zai)刀(dao)(dao)庫(ku)(ku)(ku)(ku)安裝不同用途的刀(dao)(dao)具(ju),可(ke)(ke)在(zai)(zai)一次裝夾中(zhong)通過自動(dong)(dong)換(huan)(huan)刀(dao)(dao)裝置改變主軸上的加工(gong)刀(dao)(dao)具(ju),實現鉆、鏜、鉸、攻螺紋、切槽(cao)(cao)等(deng)多(duo)種加工(gong)功(gong)(gong)能(neng),方便零件加工(gong)!
加工中(zhong)心(xin)是帶(dai)有刀庫和自動換(huan)刀裝置的數控(kong)(kong)機(ji)床,它將數控(kong)(kong)銑(xian)床、數控(kong)(kong)鏜床、數控(kong)(kong)鉆床的功能組合在一(yi)起,功能強大。
