BHD700/3
The BHD700-3 CNC beam drilling machine is engineered for high-speed, multi-surface drilling of H-beams, channel steel, and similar structural profiles. Featuring three independently controlled drilling spindles, servo-driven feeding, and intelligent CNC control, the machine delivers unmatched accuracy, automation, and throughput. It is ideal for steel structure manufacturers handling high-volume, high-precision drilling jobs.
This model supports direct import of DSTV/NC1 data, automatic tool path generation, and stable operation under continuous load. Whether you're fabricating towers, bridges, or industrial plants, the BHD700-3 offers consistent output with minimal operator intervention.
Equipped with vertical and horizontal spindles, the machine drills all three sides of the beam without repositioning, reducing cycle times and human error.
The beam is advanced using a servo-powered trolley with hydraulic clamps, ensuring accurate positioning, repeatability, and safe operation even with heavy materials.
A Siemens controller manages drilling sequences, tool changes, and speed settings, offering real-time feedback and parameter adjustments via touchscreen interface.
Centralized lubrication, internal cooling, and a conveyor-type chip removal system ensure smooth continuous drilling with low maintenance needs.

The BHD700-3 excels in a wide variety of structural steel drilling scenarios, including:
Mass production of steel columns, beams, and trusses
High-speed drilling for power transmission tower components
Channel steel processing in modular and prefabricated buildings
Bridge girder drilling in large-scale infrastructure projects
Oil & gas offshore platform framework manufacturing
By automating beam positioning and drilling execution, the machine significantly reduces cycle time and operational cost while maintaining top-level accuracy for complex hole patterns.
A: Yes, it supports a wide range of profiles, including H-beams and U-channels within the 150–700 mm height range.
A: Thanks to servo positioning and CNC control, the machine achieves drilling accuracy of ±0.1 mm.
A: Absolutely. The system accepts DSTV/NC1 files generated from Tekla Structures or similar detailing software.
A: A chain-type conveyor collects and ejects metal chips automatically during operation, ensuring clean working conditions and reduced downtime.
