Product Features:

1. The beam drilling machine is equipped with a CNC-controlled carriage clamping and feeding system, enabling rapid workpiece transportation, precise positioning, and stable material feeding throughout the complete machining cycle.

2. The equipment incorporates three high-speed BT40 spindle units, allowing simultaneous machining of the three faces of H-beam sections. When fitted with carbide cutting tools, the spindle speed can reach up to 3,000 rpm, delivering high machining efficiency, excellent drilling precision, and superior hole quality. Drilling chips are automatically collected and transported through the integrated chain-type chip evacuation system, helping maintain a clean, organized, and efficient working environment.

3. The CNC beam drilling line utilizes an advanced mist cooling system with both internal and external coolant delivery capabilities. Each drilling spindle is independently equipped with an external cooling nozzle and an internal coolant connection, enabling operators to select internal cooling, external cooling, or a combined cooling mode according to specific tooling configurations and machining conditions.

4. An Automatic Tool Changer (ATC) is available as an optional configuration based on customer-specific production requirements. The automated tool-changing mechanism eliminates manual tool replacement, minimizes non-cutting time, and further improves overall production efficiency.

5. The beam drilling system can optionally be integrated with a hydraulic CNC rotary disc marking unit. Powered by a precision servo motor, the marking disc automatically indexes and selects from 36 characters, providing rapid, accurate, and repeatable identification marking for structural steel components.

6. The automatic scribing and tapping functions eliminate traditional manual layout and marking operations. The scribing mechanism accurately creates welding reference lines on H-beam flanges and webs, supporting subsequent fabrication procedures while reducing labor requirements and enhancing processing precision. The integrated tapping function enables threaded holes to be machined directly on H-beam flanges and webs, further improving manufacturing efficiency and process integration.

7. During material feeding and machining operations, all workholding functions—including vertical lifting, lateral positioning, clamping, locking, and releasing—are controlled hydraulically. This integrated hydraulic workholding system ensures secure workpiece fixation, reliable operation, and stable machining performance during continuous industrial production.

8. The control system integrates an industrial computer with a PLC-based CNC platform and incorporates high-quality core components supplied by internationally recognized manufacturers. Multiple programming methods are available to facilitate efficient program creation, modification, and management. Structural design data generated by third-party CAD platforms, including AutoCAD and TEKLA Structures, can be directly imported in formats such as DXF and DSTV, enabling efficient integration with digital steel fabrication processes.

During sample demonstrations, the CNC H-beam drilling, marking, and shearing machine showcases its machining capabilities using standard H-beam samples with varying flange widths and web thicknesses, together with channel steel workpieces in different specifications. The demonstrated samples clearly illustrate accurate hole positioning, high-quality threaded holes, and well-defined marking results, providing customers and technical personnel with a practical basis for evaluating the machine's machining accuracy, processing consistency, and operational reliability.

The High-Speed CNC H-Beam Drilling, Marking, and Shearing Machine is primarily engineered for structural steel fabrication facilities, bridge construction projects, and other heavy-duty steel processing applications. In steel fabrication workshops, it performs precision drilling and related machining operations on H-beams used for structural frames, columns, and support assemblies, facilitating accurate and efficient steel structure installation. In bridge engineering applications, the machine provides high-precision machining of H-beam components, contributing to improved connection accuracy, structural integrity, and long-term load-bearing performance. By combining high processing efficiency, excellent machining precision, and dependable operational stability, the equipment provides an effective and reliable manufacturing solution for modern structural steel fabrication and infrastructure projects.
