1.The machine bed is separated from the worktable, and the moving column and drilling power head are installed on the bed. A powerful electromagnetic suction disk is installed on the machine’s worktable, which is used to tighten the workpieces. A manual oblique wedge type auxiliary supporting device is installed on the worktable away from the output roller to one end.

2.The drill bit power box adopts the pillow structure, adopts the large size roller guide, it is installed on the large section size column, improves the rigidity of the machine, moves up and down through the AC servo motor to drive the ball screw pair, the upper part is fitted with a balanced cylinder.

3.Drilling power box using imported high-speed precision spindle, with spindle servo motor. Automatic tool-changing function, equipped with four tool positions of the linear tool magazine, improve processing efficiency.

4.Installed a pressing cylinder on the moving column, when processing rail, press the workpieces and improve the clamping stiffness.

5.The motion of the main machine on the machine bed and the movement of the power head on the column have a single magnetic ruler detection system, which can ensure the positioning accuracy of the coordinate movement.

6.The drilling tools adopted indexable carbide U drill, the spindle adopted hollow ventilation fog cooling.

7.The loading and unloading system is used in the loading and unloading process of ordinary rail, which can realize semi-automatic production, reduce the labor intensity of workers, and greatly improve the labor productivity.
