        The machine is CNC deephole drilling machine suited for drilling 3-D or 2-D deephole system. It adopts external-chip removing method (gundrill method),by once continues drilling, it can realize the machining accuracy and surface roughness which is normally achieved by the progress of drilling, expanding and reaming. The bore accuracy is IT7-IT10, surface roughness Ra3.2-0.04μm, linearity of hole center line inferior to 0.05mm in 100mm length.

      Introduction
      Parameters
      The machine is CNC deephole drilling machine suited for drilling 3-D or 2-D deephole system. It adopts external-chip removing method (gundrill method),by once continues drilling, it can realize the machining accuracy and surface roughness which is normally achieved by the progress of drilling, expanding and reaming. The bore accuracy is IT7-IT10, surface roughness Ra3.2-0.04μm, linearity of hole center line inferior to 0.05mm in 100mm length. It is employed widely in drilling water stoma, perforation ,electric hole in the industry of glass mold, hydraulic tool , and rubber mould; the valves ,distributors, pumps in the field of hydraulic industry; the engine block, spare parts for fuel system, spare parts for transmission agent, shells for steering gears and steering shafts employed in automobiles and tractors industry; propeller and landing in aviation industry. The machine can also machine the peck on spare parts such as heat-exchanger plate in generator industry.
