這臺(tai)12米動(dong)柱式數控(kong)龍門銑床采用全包方滑(hua)枕(zhen)結構，工(gong)(gong)作臺(tai)固(gu)定(ding)直接放在(zai)地(di)基(ji)上(shang)，并且導軌(gui)安裝(zhuang)(zhuang)在(zai)床身工(gong)(gong)作臺(tai)上(shang)，導軌(gui)基(ji)準面與(yu)工(gong)(gong)作臺(tai)表面一次加工(gong)(gong)出(chu)來(lai)，精度高好安裝(zhuang)(zhuang)，大大提高了機床的承載能力，比工(gong)(gong)作臺(tai)移動(dong)的龍門銑床承載能力高幾十倍；床身短一半，鑄件少，節約成本使機床造價低。
