PM Series Gantry CNC Drilling Machine (Rotary Machining)

Product Application Introduction

This machine works for flanges or other large round parts of wind power industry and of engineering manufacture industry, the flange or plate material’s dimension maximum can be diameter 2500mm or 3000mm, the machine’s feature is drilling holes or tapping screws at very high speed with carbide drilling head, high productivity, and easy operation.

Instead of manual marking or template drilling, the machining accuracy and labor productivity of the machine are improved, the production cycle is shortened, very good machine for drilling flanges in mass production.

Details and advantages

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. 

PM Series

2. Z-direction ram is vertically installed on the Y-direction slide, which is guided by the linear roller guide pairs on both sides of the ram, driven by the lead screw pair driven by the servo motor, and balanced by the hydraulic cylinder.
3. The vertical Z-direction CNC feed ram type drilling head hydraulic cylinder is installed on the Y-direction moving slide plate of the moving gantry for balancing. The drilling head adopts the special frequency conversion motor of the spindle and drives the spindle through the synchronous belt. It has large low speed torque and can bear heavy cutting load. It is also suitable for high-speed machining of carbide tools.

PM Series1

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.

PM Series2

8. The CNC system of this machine adopts Spanish FAGOR8055, with electronic hand wheel, powerful function and simple operation. It is equipped with upper computer and RS232 interface, and has the functions of processing preview and review. The operation interface has the functions of man-machine dialogue, error compensation and automatic alarm.
