SWZ1250C
The SWZ1250C is a fully automated three-dimensional CNC drilling machine built for precision processing of large structural steel sections. Designed to handle H-beams and channel steel up to 1250 mm in height, this machine integrates intelligent feeding, multi-axis control, and CNC automation into one system. It is widely applied in steel structure plants, bridge engineering, power station boilers, and offshore platform fabrication, where accurate multi-surface drilling is essential for mass production.
With its servo-driven feeding trolley, three independent drilling units, and DSTV file compatibility, the SWZ1250C streamlines your fabrication workflow, reducing manual effort and ensuring consistent hole positioning across complex beam profiles.
The SWZ1250C features three high-rigidity spindles mounted on the top, left, and right, enabling simultaneous drilling on the web and flanges of beams. This minimizes repositioning and significantly improves production efficiency, especially in dense hole group scenarios.
Equipped with a CNC-controlled feeding trolley powered by a 5.0 kW servo motor, the system delivers stable, accurate movement for beams up to 12 meters long and 10 tons in weight. Pneumatic clamping adjusts to different beam thicknesses, ensuring secure holding during high-speed drilling.
The machine supports full compatibility with DSTV/NC1 files exported from Tekla and other steel detailing software. Hole data is imported directly and transformed into efficient tool paths, eliminating manual programming errors and saving time in part setup.
