Product Features

1. Bed and worktable:
The bed and worktable are constructed as integral castings using gray iron (HT250), subjected to secondary annealing and aging treatments, and finished with precision machining to guarantee superior dynamic and static rigidity, ensuring no deformation. The worktable surface is equipped with precision-machined T-slots in an optimized layout, facilitating secure workpiece clamping. The bed base is outfitted with two high-precision linear guideways on each side, ensuring even force distribution across the guideway slides and substantially enhancing the machine tool’s rigidity as well as its tensile and compressive resistance. The drive system utilizes AC servo motors paired with precision ball screws for dual-side actuation, enabling the gantry to traverse along the Y-axis. Adjustable bolts are strategically positioned on the bed base, allowing for straightforward calibration of the bed and worktable’s horizontal alignment.

2. Mobile gantry:
The movable saddle is a precision cast iron structural component, integrated with four high-load-bearing CNC linear guide slides, a precision ball screw assembly, and a high-precision planetary reducer linked to a servo motor. It is also equipped with a nitrogen balancing cylinder, which serves to counterbalance the weight of the power head, reduce the load on the screw, extend the screw’s service life, and drive the drilling power head to move along the Z-axis. This configuration enables operations such as rapid advancement, working feed, rapid retraction, and stopping, while incorporating automatic chip breaking, chip removal, and pause functionalities.

3. Drilling Power Head:
The drilling power head is outfitted with a dedicated servo spindle motor, which utilizes a toothed synchronous belt for speed reduction and torque amplification to drive a specialized precision spindle. The spindle incorporates a six-row Japanese angular contact bearing arrangement (four at the front, two at the rear) to enable stepless speed adjustment. It is equipped with a pneumatic tool-changing system, facilitating swift and convenient tool replacement. The feed motion is powered by a servo motor and ball screw assembly. The X and Y axes feature interlinking capabilities and employ semi-closed-loop control to achieve linear and circular interpolation functions. The spindle end is designed with a BT50 tapered hole and integrated with a high-speed rotary joint, enabling high-speed U-drill machining with center water cooling.

5. Transmission System:
Incorporating Taiwan-imported guide rails and a high-precision slider design, the transmission system ensures smooth operation while enhancing heavy-load handling capability.

The CNC gantry-type drilling, marking, and milling machine for flanges and carbon steel stands as a high-performance industrial equipment, meticulously engineered for the precision machining of plate-type components and structural parts. This apparatus is custom-designed to process workpieces such as flanges, discs, rings, and flat plates, with a core requirement that the thickness of these workpieces strictly complies with the machine’s specified effective machining range.

In steel structure workshops, this equipment provides precision drilling and milling for structural plates and connecting components, laying a solid foundation for the stable assembly of steel frameworks. Within the wind energy sector, it delivers high-precision machining solutions for wind turbine towers and flanges—an essential process that ensures these components can withstand harsh environmental conditions (e.g., strong winds, temperature variations). For bridge construction projects, the equipment processes bridge girders and support brackets, facilitating the formation of stable, durable connections designed to bear dynamic loads throughout the bridge’s extended service life.
