GMD2016 Gantry Drilling Machine

Application
This GMD2016 gantry drilling machine is mainly used for drilling plates of buildings, bridges, steel towers and other steel structures. It also can be used to drill the tube plates, baffles and circular flanges in boiler and petrochemical industries. This machine has high working efficiency and high drilling accuracy.

Technical Characteristics
This gantry drilling machine mainly consists of the worktable, gantry, hydraulic in-feeding drilling spindle, hydraulic system, NC system, cooling system and chip removal system.
1. Our CNC drilling machine is designed with fixed worktable and moveable gantry, thus is space saving. The gantry and worktable are welded structures which have steady precision due to the artificial aging treatment.
2. There are hydraulic clamps around the worktable used to clamp workpieces and the clamps can be easily controlled by foot switch.
3. The largest workpiece our drilling equipment can process is in the size of 2000×1600mm. Small workpieces can be processed at the corner of the worktable, remarkably shortening the preparation time and increasing the production efficiency.
4. Our gantry drilling machine contains 2 NC axes which are respectively the gantry movement axis (X axis) and the drilling spindle transverse movement axis (Y axis). Each axis is guided by precise linear rolling guide and driven by AC servo motor and ball screw.
5. The drilling head which is driven by the power supplied by motor and transmitted by the gears has big torque. The drilling speed can be adjusted steplessly according to actual need. The spindle adopts-quick change chuck, making drilling head replacement convenient.
6. The drill bit employs circulating water cooling. It is installed with a coolant filtering and circulating device. Under this steel structure drilling machine body, there is a plate chain chip cleaner which can automatically remove the chips to the chip trolley.
7. Controlled by a Mitsubishi PLC system together with the host computer, the NC system of our gantry drilling machine has powerful programming function to achieve direct conversion between CAD and CAM. Thanks to the PLC system, man-machine interaction and automatic alarm function are also available to help the operators to monitor the processing procedure in real time.
8. Key components such as ball screw, linear guide set, hydraulic valve, electrical component, servo motor and frequency converter of our gantry CNC drilling equipment all come from world-famous manufacturers.
