机床用途：该机床是加工圆柱形深孔零件的专用机床，适用于圆柱形深孔工件的镗削加工，镗孔时采用授油器供油，通过切削区，把切屑由排向床头的排屑斗。
机床床身导轨为矩形导轨，经淬火处理，有较高的耐磨性；床身导轨的中间，安装着进给丝杠。授油器顶紧工件采用伺服电机，安全可靠。授油器主轴与机床主轴同心度高，旋转精度好；更换导向套方便。该机床是一种操作、控制方便加工效率较高的深孔镗床。
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.
