龍門加工中心是目(mu)前世(shi)界上(shang)產(chan)量(liang)較高、應用較廣泛的(de)數控機床，其(qi)主要加工特點有：

一、在數控鏜床(chuang)或數控能床(chuang)的(de)基礎上增加自內換刀(dao)裝置，使工(gong)件在一-次裝夾(jia)后， 可以連續(xu)完成對工(gong)件表面多工(gong)序的(de)加工(gong)，工(gong)序高(gao)度集中。

二(er)、一般帶有自動分度回轉作臺(tai)或主軸(zhou)箱，可(ke)自動轉角度，從而使(shi)工件(jian)一次裝夾后(hou)自動完(wan)成多個平(ping)面或多個角度位置的多工序加工。

三、龍門加工(gong)中心(xin)能自動改變機(ji)床(chuang)主軸轉速、進給量(liang)和刀具相對工(gong)件的運(yun)動軌跡及其他輔助機(ji)能。

四、如果(guo)帶有交(jiao)換作(zuo)臺(tai)(tai)，龍門加(jia)工(gong)(gong)(gong)中(zhong)心(xin)工(gong)(gong)(gong)件(jian)在工(gong)(gong)(gong)作(zuo)位(wei)置的工(gong)(gong)(gong)作(zuo)臺(tai)(tai)進行加(jia)工(gong)(gong)(gong)的同時，另外的工(gong)(gong)(gong)件(jian)在裝(zhuang)卸位(wei)置的工(gong)(gong)(gong)作(zuo)臺(tai)(tai)上進行裝(zhuang)卸不(bu)影響正常(chang)的加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)件(jian)。
