Applicable for various of stick rod workpiece deep hole drilling,widely used in machining of CRH trains spare parts,internal combustion engine parts,nuclear power pipeline,stainless steel connections,silverworks,motor shaft,precise bypass process,graphite ,high precision pressure pipeline,molds parts,touch probe,metallurgy parts,aerospace parts and small spindle inner core etc. Uses jigs to drill special materials and eccentric orifice.
The deep hole drilling machine is time cost free for customers, small and medium factory refit the used machine to complete the deep hole drilling at earlier days,but the efficiency and accuracy is hard to be guaranteed,and the others factories rely on outsourcing service or other suppliers. the time is hard to control,as well as the delivery.
Since the deep hole drilling machine emerges in the market, besides the nationalized and military enterprises and large engineering workshops purchased,it is also popular in small and medium mold factories, which proves the DHD machine’s increasing demand in the market.

The frameworks' made of high quality Meehanite iron casting,being aging treatment,to reach a perfect stability&rigidity
The screw guides of three axes use high rigidity and high precision ball screw guides which made in Taiwan,it is durable and can output more powerful torque.The rail guides of three axes use high rigidity,heavy duty,high speed and precision linear guide,made by HIWIN,Taiwan.
The driven system of the spindle uses YASKAWA AC servo motors,connect with the ball screw guides directly,stable transmission,no back clearance,meets the machining requirements of variable speed. It was equipped with a automatic oil-cooling system,ensure a constant temperature.
