1) The machine is composed of base, gantry, drilling unit, exchangeable worktable, chip removal system, electric system and centralized lubricating system etc. 2) Two exchangeable worktables can reduce the loading and unloading time and improve the production efficiency. 3) The machine is easy to operate because it uses stroke Self-controlled drilling unit 4) Workpiece are clamped tigitly by hydraulic clamps. For small workpiece it can clamp four groups together. 5) All running station can be shown directly in the computer. 6)It uses centralized lubricating system to extend the life time of the machine. 7) High efficiency and high precision, Good stability, Easy to operate.
