機床用途：該機床是加工圓柱形深孔零件的專用機床，適用于圓柱形深孔工件的鏜削加工，鏜孔時采用授油器供油，通過切削區(qū)，把切屑由排向床頭的排屑斗。
機床床身導軌為矩形導軌，經(jīng)淬火處理，有較高的耐磨性；床身導軌的中間，安裝著進給絲杠。授油器頂緊工件采用伺服電機，安全可靠。授油器主軸與機床主軸同心度高，旋轉精度好；更換導向套方便。該機床是一種操作、控制方便加工效率較高的深孔鏜床。
The usage of the machine,the machine is special equipment for machining deep cylindrical hole of workpieces.It suitable for boring the cylindrical workpiece.When boring the hole,the oil is supply from the guide carriage,and take the chips from the cutting area to the equipment of chip conveying on the headstock.
