 This series machines are specially for the cylindrical workpiece, such as lathe's spindle holes, through holes,blind holes,step holes of all kinds of machinery hydralic oil cylinders,air cylinders. The machine can drill, bore and also press, it is adopted BTA chip-out method .
   The machine body is good in rigidity,high accuracy. The spindle speed range is wide,infeed system is driven by AC servo motor,which can meet all kinds of deep hole process,the oil supply fasten device and workpiece clamping device adopts hydralic system,and show the pressure value,safty and reliable.
   We can also make similar machines basing on the above machine,different length. We can make this kind of machines according to customer's requirement.
