數(shu)(shu)控車床又稱為CNC數(shu)(shu)控車床，是目(mu)前國內使用量{zd0}，覆蓋面最廣的一(yi)(yi)種數(shu)(shu)控機(ji)床。數(shu)(shu)控車床是集機(ji)械、電(dian)氣、液壓、氣動、微(wei)電(dian)子和(he)信息等(deng)多(duo)項技(ji)術為一(yi)(yi)體的機(ji)電(dian)一(yi)(yi)體化產品。

數(shu)控(kong)(kong)車床(chuang)(chuang)是精密機械和自動(dong)(dong)化技術的(de)綜合體。機床(chuang)(chuang)的(de)數(shu)控(kong)(kong)裝置可以對機床(chuang)(chuang)運動(dong)(dong)中產生的(de)位移、熱變(bian)形等導致的(de)誤差，通(tong)過測量系(xi)統(tong)進行補償而獲得(de)很高且穩定的(de)加工精度。由于數(shu)控(kong)(kong)車床(chuang)(chuang)實現自動(dong)(dong)加工，所以減少(shao)了操作人(ren)員(yuan)素質帶(dai)來的(de)人(ren)為誤差，提高了同批零件的(de)一致性。

就(jiu)生產效率而言(yan)，相對普(pu)通(tong)機(ji)床(chuang)，諾信(xin)數控車床(chuang)定制廠家的(de)數控車床(chuang)的(de)效率一般能(neng)提高2～3倍、甚至十幾倍。主(zhu)要體現在以下幾個方面：1、一次裝(zhuang)夾完成多工(gong)(gong)序(xu)加工(gong)(gong)，省去了(le)(le)普(pu)通(tong)機(ji)床(chuang)加工(gong)(gong)的(de)多次變換(huan)工(gong)(gong)種、工(gong)(gong)序(xu)間的(de)轉件以及(ji)劃(hua)線等(deng)工(gong)(gong)序(xu)。2、簡化了(le)(le)夾具及(ji)專(zhuan)用(yong)工(gong)(gong)裝(zhuang)等(deng)，由(you)于是一次裝(zhuang)夾完成加工(gong)(gong)。所(suo)以普(pu)通(tong)機(ji)床(chuang)多工(gong)(gong)序(xu)的(de)夾具省去了(le)(le)，即使偶爾必須用(yong)到專(zhuan)用(yong)夾具。

數控(kong)(kong)車床(chuang)(chuang)廠(chang)家的控(kong)(kong)機(ji)(ji)床(chuang)(chuang)硬質(zhi)臺金可轉位(wei)式(shi)面銑刀(dao)(dao)(dao)主要(yao)用于(yu)銑削(xue)平面。粗銑時，銑刀(dao)(dao)(dao)直(zhi)徑(jing)選小(xiao)一些(xie)(xie)，因為粗銑時切削(xue)力大，選小(xiao)直(zhi)徑(jing)銑刀(dao)(dao)(dao)可減小(xiao)切削(xue)力矩。數控(kong)(kong)車床(chuang)(chuang)精銑時，銑刀(dao)(dao)(dao)直(zhi)徑(jing)選大一些(xie)(xie)，能(neng)包容(rong)待加工面的整個(ge)寬度，以提高加T精度和效率。機(ji)(ji)床(chuang)(chuang)加工余量大且不均(jun)勻時，刀(dao)(dao)(dao)具(ju)直(zhi)徑(jing)應選小(xiao)一些(xie)(xie)，否則，會因掛刀(dao)(dao)(dao)刀(dao)(dao)(dao)痕過深而影響(xiang)工件的加丁質(zhi)量。

高速鋼立銑刀多用(yong)于加(jia)工凸臺和凹槽，一般不用(yong)來加(jia)工毛坯表面-因為毛坯表面的硬化層和夾砂會加(jia)快刀具磨損。

加(jia)工(gong)(gong)(gong)毛(mao)坯表(biao)面或(huo)粗加(jia)工(gong)(gong)(gong)孔(kong)時(shi)(shi)(shi)，可選鑲硬質合金的(de)立(li)銑(xian)(xian)刀(dao)(dao)(dao)或(huo)玉(yu)米(mi)銑(xian)(xian)刀(dao)(dao)(dao)進行(xing)強力(li)切削(xue)。加(jia)工(gong)(gong)(gong)平(ping)面工(gong)(gong)(gong)件周邊輪廓時(shi)(shi)(shi)，常采(cai)用(yong)立(li)銑(xian)(xian)刀(dao)(dao)(dao)C。為(wei)了提高槽(cao)寬的(de)加(jia)精度，減少換(huan)刀(dao)(dao)(dao)次數(shu)，加(jia)工(gong)(gong)(gong)時(shi)(shi)(shi)可采(cai)用(yong)直徑(jing)比槽(cao)寬7的(de)銑(xian)(xian)刀(dao)(dao)(dao)，先銑(xian)(xian)槽(cao)的(de)中間部分，然(ran)后利(li)用(yong)刀(dao)(dao)(dao)具(ju)半徑(jing)補償(chang)功能銑(xian)(xian)削(xue)槽(cao)的(de)兩邊。加(jia)工(gong)(gong)(gong)立(li)體曲面或(huo)變斜角輪廓外形(xing)時(shi)(shi)(shi)，常采(cai)用(yong)球(qiu)頭銑(xian)(xian)刀(dao)(dao)(dao)、環形(xing)銑(xian)(xian)刀(dao)(dao)(dao)、鼓(gu)形(xing)銑(xian)(xian)刀(dao)(dao)(dao)、錐形(xing)銑(xian)(xian)刀(dao)(dao)(dao)、盤形(xing)銑(xian)(xian)刀(dao)(dao)(dao)等。當(dang)加(jia)工(gong)(gong)(gong)余量較(jiao)小，且表(biao)面粗糙度要求(qiu)較(jiao)高時(shi)(shi)(shi)，可選用(yong)鑲立(li)方氮化硼刀(dao)(dao)(dao)片或(huo)鑲陶(tao)瓷刀(dao)(dao)(dao)片的(de)面銑(xian)(xian)刀(dao)(dao)(dao)，以便能進行(xing)機床高速切削(xue)。
