1.The machine is mainly composed of base, gantry, drilling unit, exchangeable worktable, chip removal system, electric system, hydraulic system and centralized lubricating system etc.

2.There are two exchangeable worktables in the machine, while the workpiece on one worktable is being drilled, the other worktable can be moved out to unload the finished workpiece and load a new workpiece. These exchangeable worktables can greatly reduce the loading and unloading time and improve the production efficiency.

3.This machine used stroke self-controlled drilling unit. Rapid feeding,working feed and rapid withdrawing are transformed automatically without presetting any parameters manually such as the length of the drill and the thickness of the workpiece before operating, so that the machine is easy to operate.

5.Workpieces are clamped tightly by hydraulic clamps, For small work pieces the machine can clamp four groups together so as to reduce the preparation period of production and increase the efficiency.

6.The software of host computer is humanized designed. The machine’s running data can be shown directly on the real time monitor and I/O monitor interfaces.

7.The machine uses centralized lubricating system to make sure all the function parts being well lubricated thus improve the performance and extend the lifetime of the machine.
