Product Features:

1. The material feeding system adopts a CNC-controlled clamping carriage driven by high-performance servo motors, providing rapid and stable workpiece transportation while maintaining excellent positioning accuracy and repeatability throughout the entire machining process.

2. The machine is equipped with three high-speed BT40 precision spindle units designed to simultaneously machine all three surfaces of H-beam sections. Supporting carbide drilling operations, through-spindle coolant delivery, and spindle speeds of up to 3,000 rpm, the system delivers outstanding drilling performance, high-quality hole processing, and efficient chip evacuation through the integrated chain-type chip conveyor.

3. An advanced Minimum Quantity Lubrication (MQL) cooling system is incorporated into the machine, supporting both internal and external coolant delivery modes. Each spindle is equipped with an independent external coolant nozzle and internal coolant channel, allowing operators to select internal cooling, external cooling, or combined cooling according to specific tooling requirements and machining conditions.

4. The equipment can be optionally configured with an Automatic Tool Changer (ATC) system, enabling fully automatic tool replacement without manual intervention. This advanced configuration significantly reduces tool exchange time, minimizes machine idle periods, and enhances overall production efficiency.

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

6. The integrated automatic scribing and tapping functions eliminate conventional manual layout and preparation procedures. The scribing unit accurately creates welding reference lines on both H-beam flanges and webs, while the tapping function directly machines threaded holes on structural members, improving machining precision, reducing labor requirements, and increasing overall manufacturing productivity.

7. Throughout the entire material feeding and machining cycle, workpiece lifting, lateral positioning, clamping, locking, and releasing operations are fully controlled by the hydraulic system. This advanced hydraulic workholding design ensures secure material fixation, superior machining stability, and reliable performance during continuous industrial production.

8. The CNC control system integrates an industrial computer with a PLC-based CNC platform and utilizes premium components from internationally recognized manufacturers. The system supports multiple programming methods and enables direct import of machining data generated from AutoCAD, TEKLA Structures, DXF, and DSTV files, simplifying programming procedures and improving production management efficiency.

The demonstration workpieces include standard H-beam samples with various flange widths and web thicknesses, as well as channel steel components in different specifications, providing a comprehensive demonstration of the machine’s processing capabilities. These representative samples clearly illustrate the equipment’s ability to achieve precise hole positioning, excellent thread machining quality, and accurate marking results. They enable customers, engineers, and quality inspection personnel to effectively evaluate machining accuracy, production consistency, and operational reliability under actual manufacturing conditions.

The High-Speed CNC H-Beam Drilling, Marking, and Tapping Machine is extensively applied in structural steel fabrication plants, bridge construction projects, and various heavy steel manufacturing industries. In steel fabrication workshops, the equipment performs high-precision drilling, tapping, marking, and scribing operations on H-beams used for structural frames, columns, and support assemblies, providing accurately processed components for efficient installation and dependable structural performance. For bridge engineering applications, the machine delivers precise machining of H-beam structural members, enhancing connection accuracy, structural integrity, and long-term load-bearing performance. By combining high production efficiency, exceptional machining precision, and stable operational reliability, the equipment provides an advanced manufacturing solution for modern steel structure fabrication and large-scale infrastructure construction projects.
