At Openex Metal Fab, we believe that empowering our clients to tackle the most ambitious engineering projects starts with investing in foundational manufacturing technology. That’s why we are proud to announce a significant expansion of our heavy-machining capabilities with the acquisition and commissioning of a state-of-the-art, gantry-type 5-Axis CNC Milling and Turning Center from BYJC. This "mega machine" is a game-changer for industries that demand precision on a monumental scale.
This strategic addition is far more than just another piece of equipment; it is a testament to our commitment to providing comprehensive, large-scale metal fabrication solutions and solidifying our position as a leading partner for heavy industrial fabrication.
Designed to handle the most challenging and oversized components, this machine solves critical pain points in large-part manufacturing. Its specifications speak to its unparalleled capacity:
Massive Work Envelope & Capacity: A fixed table length of 20 meters (65.6 ft), a rotary table diameter of 10.5 meters (34.4 ft), and an astounding maximum load capacity of 300 metric tons. This allows us to secure and process entire sections of mining machinery, massive energy sector components, and large-scale capital equipment frames in one location.
Revolutionary 5-Face Machining in a Single Setup: The machine’s true innovation lies in its integrated 5-axis simultaneous milling and turning capabilities. Traditionally, colossal parts require multiple moves between different machines for milling, boring, and turning operations. Each move introduces potential alignment errors, increases handling time and risk, and extends lead times.
Our Solution: With this mill-turn center, we can complete roughing and finishing operations on up to five faces of a part in a single clamping. This eliminates cumulative errors, guarantees superior dimensional integrity and positional accuracy, and dramatically accelerates project timelines.
Unmatched Stability & Precision: Engineered for heavy-duty machining, the machine’s robust construction ensures exceptional vibration damping and thermal stability. This translates to finer surface finishes, tighter tolerances, and reliable, repeatable performance even during aggressive material removal on tough alloys.
This machine is engineered for sectors where size, complexity, and reliability are non-negotiable:
Energy (Wind, Hydro, Nuclear): Manufacturing large gearbox housings, turbine hubs, and reactor components.
Heavy Engineering & Mining: Producing giant structural frames, base plates, and slewing rings for excavators and draglines.
Capital Equipment: Fabricating critical components for presses, machine tool bodies, and other large industrial systems.
By consolidating multi-step processes, we reduce supply chain complexity for our clients, ensure higher quality, and provide a faster, more secure path from design to delivery.
The introduction of the BYJC mill-turn center doesn't operate in isolation. It synergizes with our existing world-class equipment roster to create a true one-stop manufacturing hub. Our capability matrix includes:
Cutting & Welding: 100+ advanced laser cutters and 100+ welding systems for precision preparation.
Heavy Machining Fleet: Multiple large-scale floor-type boring mills, deep-hole drilling units, and a celebrated German-made SCHIESS VGM6 double-column milling center—one of the world's largest—with 7-axis control for ultra-complex geometries in aerospace and power generation.
Forming & Bending: A range from Swedish URSVIKEN 3000-ton CNC press brakes to automated TRUMPF bending cells that enable 24/7, lights-out production for high-volume precision parts.
Rolling & Pressing: Swedish HÄUSLER plate rolls capable of hot-rolling 300mm thick steel and our in-house designed and built 5000-ton press showcasing our custom fabrication prowess.
This integrated ecosystem allows Openex to manage a project from raw plate and forging through final precision machining and quality control, offering unparalleled supply chain security, quality consistency, and project management efficiency.
At Openex Metal Fab, we are more than a fabricator; we are a strategic manufacturing partner. The investment in this colossal 5-axis CNC technology reflects our forward-thinking approach:
Anticipating Market Needs: We are proactively building capacity for the trend toward larger, more integrated, and more reliable industrial equipment.
Driving Manufacturing Excellence: We leverage cutting-edge technology not just for capacity, but to pioneer smarter, more efficient manufacturing methodologies for our clients.
Empowering Client R&D: Our capabilities allow design engineers to push boundaries, knowing that fabrication constraints for massive, high-precision parts can be overcome.
