Product Features:

1. The material feeding system adopts a CNC-controlled clamping carriage driven by high-performance servo motors, providing rapid workpiece transportation together with outstanding positioning accuracy and repeatability throughout the machining cycle.

2. Three high-speed BT40 precision spindle units are arranged to simultaneously machine all three faces of H-beam sections. Supporting carbide drilling with through-spindle coolant and spindle speeds of up to 3,000 rpm, the system delivers superior drilling efficiency, excellent hole quality, and effective chip removal through an integrated chain-type chip conveyor.

3. The machine features an advanced Minimum Quantity Lubrication (MQL) cooling system supporting both internal and external coolant delivery. Each spindle assembly is equipped with an independent external spray nozzle and an internal coolant interface, allowing operators to select internal cooling, external cooling, or a combined cooling mode according to specific machining requirements.

4. An optional Automatic Tool Changer (ATC) is available to perform fully automatic tool replacement without manual assistance, significantly reducing changeover time, minimizing machine idle time, and improving overall production efficiency.

5. An optional hydraulic CNC rotary disc marking system can be incorporated into the machine. Driven by a precision servo motor, the marking disc automatically indexes among 36 selectable characters, providing fast, accurate, and repeatable identification marking for structural steel components.

6. Automatic scribing and tapping functions eliminate conventional manual layout operations. The scribing unit precisely marks welding reference lines on both the flanges and webs of H-beams, while the tapping function directly produces threaded holes in structural members, enhancing machining precision, reducing labor input, and increasing manufacturing efficiency.

7. During material feeding and machining, workpiece lifting, side positioning, clamping, locking, and release are all hydraulically actuated. This fully hydraulic workholding system ensures secure material fixation, outstanding machining stability, and reliable performance during continuous production.

8. The control system integrates an industrial computer with a PLC-based CNC platform utilizing high-quality components from internationally recognized manufacturers. Multiple programming methods are supported, while machining data generated from AutoCAD, TEKLA Structures, DXF, and DSTV files can be imported directly, streamlining programming procedures and improving production management efficiency.

The demonstration workpieces include standard H-beam specimens with various flange widths and web thicknesses, together with channel steel samples of different specifications, providing a comprehensive display of the machine's machining performance. These representative samples clearly demonstrate precise hole positioning, high-quality threaded holes, and sharp, well-defined marking results, allowing customers, engineers, and quality inspectors to accurately evaluate the equipment's machining precision, processing consistency, and overall production reliability under practical operating conditions.

The High-Speed CNC H-Beam Drilling, Marking, and Tapping Machine is extensively applied in structural steel fabrication plants, bridge engineering, and other heavy steel construction industries. Within steel fabrication facilities, the equipment performs high-precision drilling, tapping, marking, and scribing on H-beams used for structural frames, columns, and support systems, supplying accurately machined components for efficient assembly and dependable structural performance. In bridge construction projects, it provides precision machining of H-beam members, improving connection accuracy, structural integrity, and long-term load-bearing performance. By combining high machining efficiency, outstanding precision, and reliable operational stability, the machine delivers an ideal manufacturing solution for modern steel structure production and large-scale infrastructure construction.
