1. The machine is mainly composed of bed and longitudinal slide, gantry and transverse slide, automatic clamping chuck, vertical ram drilling head, hydraulic system, cooling system, electrical system, automatic lubrication and other parts. 
4. Taiwan precision spindle (internal cooling) is adopted for the drilling spindle of this machine. The spindle taper hole BT50 has butterfly spring automatic broach mechanism. 5. The automatic clamping chuck is used to clamp the annular material automatically, and the clamping force is easy to adjust. The chuck is separated from the bed to realize fast automatic clamping and reliable operation. 6. The X-axis guide rails on both sides of the machine are installed with stainless steel protective cover, and the Y-axis guide rails are installed with flexible protective cover at both ends, with soft limit function. 7. The machine is equipped with flat chain chip conveyor, chip receiving box is flip type, and cooling system with paper filter, and the coolant is recycled.
