Product Features

1. Machine Bed and Workbench:
The machine bed and workbench are integrally cast from gray cast iron (HT250), undergoing double annealing and aging treatments prior to final precision machining. This manufacturing process ensures excellent static and dynamic rigidity, as well as dimensional stability without deformation. The workbench surface is precision-machined with rationally arranged T-slots, specifically designed for secure workpiece clamping. Two high-precision linear guides are installed on each side of the bed base, enabling uniform force distribution on the guide sliders to significantly enhance the machine tool’s overall rigidity and resistance to tension and compression. The drive system employs AC servo motors paired with precision ball screws to synchronously drive the gantry’s Y-axis movement on both sides. Adjustable anchor bolts are strategically distributed on the bed’s bottom surface, facilitating convenient leveling of the machine bed and workbench.

2. Fixed Beam/Mobile Gantry:
The fixed-beam gantry is fabricated via casting from gray cast iron (HT250). Two sets of ultra-high load-bearing rolling linear guides are mounted on the front side of the gantry. A precision ball screw paired with a servo motor drives the power head sliding plate to move along the X-axis, and the sliding plate is equipped with a drilling power head as standard. The gantry’s movement is realized through a servo motor, which transmits power via a precision coupling to drive the ball screw nut for rotational motion on the ball screw.

3. Mobile Saddle:
The mobile saddle is a precision cast iron structural component. It is equipped with two sets of ultra-high load-bearing CNC linear guide slides, a set of precision ball screw assemblies, and a high-precision planetary reducer that connects to the servo motor. The design incorporates power head weight balancing, which reduces the load on the ball screw and extends its service life. The saddle drives the drilling power head to move along the Z-axis, enabling functions such as rapid forward movement, rapid retraction, and stopping of the power head. It also features automatic chip breaking, chip evacuation, and pause capabilities as standard.

4. Drilling Power Head:
The drilling power head is configured with a dedicated servo spindle motor, which transmits power to a specialized precision spindle via a toothed synchronous belt to enhance torque output. The spindle incorporates a Japanese-manufactured angular contact bearing assembly (four rows at the front, two rows at the rear) and supports stepless speed regulation. Equipped with a pneumatic tool changing system, the spindle enables quick and efficient tool replacement. Feed motion is driven by a servo motor paired with a ball screw. The X and Y axes support linkage operation and adopt semi-closed-loop control, realizing linear and circular interpolation functions. The spindle nose features a BT50 taper hole and is fitted with a high-speed rotary joint, supporting high-speed U-drill machining with through-spindle coolant supply.

This high-performance CNC gantry-type industrial equipment, specialized in plate and sheet metal drilling and marking, is elaborately engineered for the precision machining of plate-type components and structural parts. Specifically tailored for processing workpieces including flanges, discs, rings, and flat plates, it features a core specification wherein the thickness of such workpieces must strictly conform to the machine’s predefined effective machining parameters.

In steel structure workshops, this equipment performs precision drilling and milling operations on structural plates and connecting components, thereby establishing a robust foundation for the stable assembly of steel frameworks. Within the wind energy sector, it provides high-precision machining solutions for wind turbine towers and flanges—an indispensable process that ensures these components can withstand harsh environmental conditions (e.g., strong winds, temperature fluctuations). For bridge construction initiatives, the equipment processes bridge girders and support brackets, enabling the formation of stable, durable connections engineered to endure dynamic loads throughout the bridge’s prolonged service life.
