Split Type CNC Gantry-Type Drilling Tapping Milling Boring Machine Model PHD2020
Application:
The CNC gantry-type drilling and milling machine for steel plates is primarily employed for machining tube sheets, flanges, bearings, heat exchangers, and other components across industries such as petrochemicals, nuclear power, wind energy, boilers, and steel structures. It accommodates high-speed drilling using carbide drill bits with internal cooling or high-speed twist drills with external cooling. The machine provides a comprehensive range of functions, including drilling, chamfering, tapping, milling, and boring. Additionally, it can be optionally fitted with an automatic right-angle head to perform side drilling, tapping, and milling operations.

Product features
1. The plate and flange drilling, milling, and marking machine consists of several key components, including a base, longitudinal slide, gantry, transverse slide, vertical feed unit, drilling and milling spindle, worktable, cooling system, automatic chip removal system, automatic lubrication system, pneumatic system, electrical system, and other essential elements.
2. The servo-driven sliding drilling power head of the CNC steel plate cutting machine is capable of performing drilling, reaming, tapping, chamfering, and groove milling operations. It can function either in coordination with other units or independently. The drilling spindle is equipped with a high-precision, Taiwan-manufactured spindle (internal cooling) with a BT50 taper and features a butterfly spring automatic broaching mechanism. This design allows for convenient tool changes via a connecting rod and hydraulic cylinder tool release system, enabling rapid switching between drill bits and milling cutters.
3. The drilling and marking machine is built with high-precision linear guides, providing smooth and accurate movement. An AC servo motor drives a synchronous belt and precision ball screw assembly, ensuring exceptional positioning accuracy.
4. The frame and gantry of the metal plate gantry machine are fabricated from castings or welded high-grade steel plates. These components undergo high-temperature annealing prior to machining, followed by a secondary annealing process after semi-finishing to relieve internal stresses. They are then precision-machined to ensure consistent accuracy and structural stability.
The CNC gantry plate cutting machine is a high-performance industrial system, carefully designed for the precise machining of plate-shaped components and structural elements. It is specifically engineered to handle workpieces such as flanges, discs, rings, and flat plates, provided that the material thickness is within the machine’s specified effective machining capacity.
In steel structure fabrication workshops, this plate drilling machine performs precise drilling and milling operations on structural plates and connecting components, providing a reliable foundation for the stable assembly of steel frameworks. Within the wind energy sector, it delivers high-accuracy machining for wind turbine towers and flanges—an essential process that ensures these components can withstand demanding environmental conditions, including high winds and temperature fluctuations. In bridge construction projects, the machine processes bridge girders and supports, facilitating the creation of stable and durable connections capable of enduring dynamic loads throughout the bridge’s service life.
