Taiwan’s high-end furniture and commercial fixture manufacturing sector is globally recognized for structural durability, precision engineering, and sleek modern aesthetics. When producing heavy-duty commercial desks, industrial shelving, and architectural seating frames, manufacturers frequently combine closed hollow sections with open structural profiles.
However, processing thick-walled 50mm x 150mm x 6mm (6t) rectangular tubing and U-channel steel poses significant mechanical challenges. To eliminate multi-stage manual processing, prevent clamping deformation, and accelerate assembly, a leading Taiwanese furniture manufacturer partnered with LONX LASER to integrate the K26III (LX-K26-3)—an industrial-grade tube fiber laser cutting machine engineered for heavy profiles.
Customer Location: Taichung / Changhua Manufacturing Hub, Taiwan
Industry: Commercial & Heavy-Duty Metal Furniture Manufacturing
Machine Model: LONX LASER K26III (Three-Chuck Tube Fiber Laser Cutting Machine)
Processed Profiles: Rectangular Tubing & Open U-Channel Steel
Workpiece Dimensions: 50mm x 150mm x 6mm (6t heavy wall thickness)
End Products: Heavy-duty modular office workstations, commercial load-bearing shelving racks, and designer structural furniture bases
Before deploying the K26III, the Taiwanese factory relied on bandsaws, hydraulic punch presses, and manual milling machines to fabricate their 50x150x6mm structural components. Processing both rectangular pipes and asymmetrical U-channel steel on traditional machinery created severe production bottlenecks:
Clamping Instability on Open U-Channel Steel: Unlike closed rectangular tubes, U-channel steel has an open cross-section that easily twists, flexes, or collapses under traditional two-chuck clamping pressure during high-speed rotation.
Slow Processing on 6mm Thick Walls: Punching and drilling 6mm-thick steel profiles caused rapid tool wear, heavy inner/outer burrs, and inconsistent hole alignment—requiring hours of manual grinding before powder coating.
High Material Waste (Tailings): Standard dual-chuck machines left long unusable off-cuts on heavy 50x150mm profiles, driving up raw steel costs.
To solve these issues, the client evaluated global channel steel laser cutting machine factories to find a heavy duty laser tube cutting machine capable of handling both closed rectangular tubes and open structural profiles in a single automated setup.
The manufacturer installed the LONX LASER K26III, a high-rigidity, three-chuck tube fiber laser cutting machine purpose-built for large-diameter tubes, thick-walled profiles, and open structural steel.
Standard two-chuck cutters struggle to maintain concentricity on asymmetrical open sections. The K26III utilizes a synchronized three-chuck system with adaptive pressure control. It securely grips the 50x150x6mm U-channel steel across multiple points without crushing the open flanges, ensuring rock-solid stability during high-speed cutting.
With thick-walled 50x150x6mm steel, tailing scrap directly impacts profit margins. The K26III’s movable middle and front chucks work in tandem to pass the workpiece through the cutting zone, achieving true zero-tail cutting and saving significant raw material costs across large production runs.
Powered by a high-efficiency fiber laser source and an intelligent CNC tube-cutting system, the K26III slices cleanly through 6mm carbon and alloy steel. Bolt holes, interlocking mortise-and-tenon joints, and 45-degree miter cuts emerge smooth and slag-free—ready for immediate robotic welding without secondary deburring.
Measurable Production Results in Taiwan
After integrating the LONX LASER K26III into their Taichung facility, the furniture manufacturer achieved substantial operational improvements:
3x Faster Cycle Times: Consolidating sawing, punching, and milling into a single automated laser cycle increased daily output of 50x150x6mm parts by over 210%.
Zero Secondary Deburring: Smooth, perpendicular cut edges eliminated manual grinding stations, allowing components to move straight to welding and surface finishing.
Near-Zero Tailing Scrap: Three-chuck zero-tailing technology reduced material waste by over 12%, delivering rapid return on investment.
As furniture designs evolve toward bolder, heavier architectural structures, relying on traditional mechanical cutting limits both creativity and profitability. As one of the leading channel steel laser cutting machine factories, LONX LASER designs the K26III to give manufacturers unmatched versatility across round tubes, rectangular profiles, and open structural steel.
