Professional High Speed CNC Plate Drilling And Milling Machine With Central Cooling

Product Introduction:

The Gantry CNC Drilling Machine is primarily designed for drilling, counterboring, chamfering, tapping, and light milling operations on rectangular tubes, steel plates, and various structural components.

Conventional radial drilling machines typically require one operator per machine and involve manual layout marking, drilling template preparation, and pilot-hole machining. These procedures are labor-intensive, difficult to integrate into continuous production, and associated with potential safety risks, limited machining accuracy, and inconsistent workpiece quality. CNC drilling technology effectively addresses these limitations. A single operator can manage multiple machines, while programmed machining and three-axis coordinated automatic positioning significantly reduce manual labor requirements. This automated configuration supports continuous production, increases manufacturing efficiency, minimizes operational safety risks, and delivers improved machining precision and workpiece consistency.

Product Features

1. The machine tool primarily consists of a machine bed, worktable, gantry, power head, CNC control system, cooling system, and other essential assemblies.

2. The Gantry CNC Drilling Machine features a fixed-bed worktable combined with a movable gantry configuration, incorporating a vibration-damping gantry structure to enhance operational stability.

3. The machine bed, columns, worktable, and gantry are manufactured from HT250 cast iron, while the supporting brackets are fabricated from welded rectangular steel tubing. High-temperature annealing is performed before initial machining, followed by a secondary stress-relief annealing process after semi-finishing to eliminate residual internal stress. Final precision machining is then completed to maintain long-term dimensional stability and machining accuracy. The cast-iron worktable is precision-machined with T-slots, and its surface undergoes CNC-controlled precision grinding to ensure excellent flatness and positioning accuracy.

4. The gantry CNC drilling machine is equipped with three CNC-controlled axes. Heavy-duty linear guideways are installed on the machine structure to ensure smooth and stable movement. The gantry travels longitudinally along the guideways in the X-axis direction, while the linear guideways mounted on the gantry beam allow the slide carriage to move horizontally along the Y-axis. The power head is installed on the slide carriage and moves vertically along the Z-axis. All three axes are driven by CNC servo motors coupled with precision ball screws, providing accurate positioning and reliable motion control.

5. The power head spindle is driven by a precision spindle assembly and servo spindle motor, allowing stepless speed adjustment according to specific machining requirements. A BT40 tool holder enables the spindle to accommodate drilling, tapping, and milling tools. The machine is also equipped with a pneumatic tool-clamping cylinder, supporting convenient one-touch automatic tool changing, high positioning accuracy, and high-speed machining performance.

6. The machine adopts a water-cooled configuration and is equipped with an integrated coolant supply, recovery, and circulation system. An automatic lubrication system provides continuous lubrication to the linear guideways and ball screws, supporting smooth movement and reliable long-term operation. The equipment can also be fitted with a high-speed spindle featuring internal and external coolant delivery, accommodating various internally cooled cutting tools, including U-drills, spade drills, crown drills, carbide internal-cooling drills, and core drills.

7. The control system utilizes a KND CNC controller, while the electrical drive system incorporates high-precision absolute-value servo motors. Standard configurations include an RS232 communication interface, a color display, and a Chinese-language operating interface. Workpiece programs can be imported through local or external USB connections, providing convenient and straightforward operation. The machine is also equipped with a fully digital high-speed electronic handwheel, enabling more precise, responsive, and efficient manual control.

The CNC gantry plate cutting machine is a durable industrial system, carefully designed for accurate machining of plate-shaped components and structural elements. It is specifically configured to handle workpieces such as flanges, discs, rings, and flat plates, provided that the material thickness falls within the machine’s specified effective machining range.

In steel structure manufacturing facilities, this plate drilling machine performs precise drilling and milling operations on structural plates and connecting elements, providing a reliable foundation for the assembly of robust steel frameworks. Within the wind energy industry, it delivers high-accuracy machining for wind turbine towers and flanges—critical processes that ensure these components can endure harsh environmental conditions, including strong winds and temperature variations. In bridge construction applications, the machine processes bridge girders and supports, facilitating the creation of stable and durable connections capable of withstanding dynamic loads throughout the bridge’s service life.
