  數(shu)控(kong)加(jia)工(gong)(gong)中(zhong)心(xin)是指備有刀庫,具(ju)有自(zi)動(dong)(dong)換(huan)刀功能,對工(gong)(gong)件(jian)一次裝(zhuang)夾后(hou)進(jin)行多(duo)工(gong)(gong)序加(jia)工(gong)(gong)的(de)(de)數(shu)控(kong)機(ji)床(chuang)。數(shu)控(kong)加(jia)工(gong)(gong)中(zhong)心(xin)是高度機(ji)電(dian)一體(ti)化的(de)(de)產(chan)品,工(gong)(gong)件(jian)裝(zhuang)夾后(hou),數(shu)控(kong)系統能控(kong)制機(ji)床(chuang)按不同(tong)工(gong)(gong)序自(zi)動(dong)(dong)選擇、更換(huan)刀具(ju),自(zi)動(dong)(dong)對刀、自(zi)動(dong)(dong)改變主軸轉速、進(jin)給量(liang)等,可連續完成鉆、鏜、銑(xian)、鉸、攻絲等多(duo)種(zhong)工(gong)(gong)序。因而(er)大(da)大(da)減少(shao)了(le)工(gong)(gong)件(jian)裝(zhuang)夾時間,測量(liang)和機(ji)床(chuang)調整等輔助工(gong)(gong)序時間,數(shu)控(kong)加(jia)工(gong)(gong)中(zhong)心(xin)對加(jia)工(gong)(gong)形狀(zhuang)比較復雜,精度要求較高,品種(zhong)更換(huan)頻繁的(de)(de)零(ling)件(jian)具(ju)有良好的(de)(de)經濟效果(guo)。

  數(shu)控加工中心通常以主(zhu)軸與工作臺相對位置分類,分為臥式(shi)、立式(shi)和萬能加工中心。

  (1)臥式加(jia)工中(zhong)心:是指主軸(zhou)軸(zhou)線與工作(zuo)臺平行(xing)設(she)置的加(jia)工中(zhong)心,主要適用于加(jia)工箱體類零件。

  (2)立式加工中(zhong)心:是指主軸軸線與(yu)工作臺垂直設置(zhi)的加工中(zhong)心,主要適用于加工板類、盤(pan)類、模具及小型(xing)殼體類復雜零件(jian)。

  (3)萬能(neng)加(jia)(jia)工(gong)(gong)中心(xin)(又(you)稱多軸(zhou)聯動型加(jia)(jia)工(gong)(gong)中心(xin)):是指(zhi)通過加(jia)(jia)工(gong)(gong)主軸(zhou)軸(zhou)線(xian)與工(gong)(gong)作臺回轉軸(zhou)線(xian)的(de)角度(du)可(ke)控制(zhi)聯動變化,完(wan)成復(fu)雜空間曲面加(jia)(jia)工(gong)(gong)的(de)加(jia)(jia)工(gong)(gong)中心(xin)。適(shi)用于(yu)具(ju)(ju)有復(fu)雜空間曲面的(de)葉輪轉子、模具(ju)(ju)、刃具(ju)(ju)等(deng)工(gong)(gong)件的(de)加(jia)(jia)工(gong)(gong)。
