Industrial-grade CNC fiber laser tube cutter designed for high payload capacity (up to 500 kg), large tube diameters (Φ20–280 mm), and versatile profile cutting with ultra-short tail scrap.
The LONX LX-K28 is a high-performance laser cutting machine for heavy tubes, engineered specifically to handle large-diameter pipes, thick-walled steel sections, and structural profiles. Built with an annealed high-rigidity side-mounted bed, a 290×290 full-stroke pneumatic chuck system, and an intelligent EtherCAT-based BOCHU CNC controller, the LX-K28 delivers unmatched cutting speed, dynamic accuracy, and scrap minimization for heavy fabrication industries.
Equipped with a side-mounted bed structure welded from premium steel and treated with high-temperature annealing, the machine easily handles heavy raw materials with single-tube loads up to 500 kg and linear densities up to 83 kg/m, preventing frame deformation during prolonged high-speed cutting.
No manual jaw adjustment required. The pneumatic full-stroke chuck automatically clamps round tubes (Φ20–280 mm), square tubes (20×20–280×280 mm), rectangular tubes, channel steel, angle iron, and I-beams with a repeat positioning accuracy of ±0.03 mm and a maximum rotation speed of 80 rpm.
The movable rear chuck avoidance system cooperates with specialized nesting algorithms to achieve minimum tail lengths (standard ≥100 mm; optional zero-tailing function), drastically reducing raw material waste on high-cost structural pipes.
Optional semi-automatic loading (5,500–6,500 mm raw pipe) and servo follow-up centering/unloading systems prevent heavy pipes from sagging or vibrating, guaranteeing precise cut bevels, slots, and intersecting line holes.
The LX-K28 is widely deployed across structural metal fabrication and heavy machinery sectors:
Steel Structures & Infrastructure: Prefabricated beams, trusses, and columns.
Bridge & Transmission Tower Engineering: High-precision intersecting hole and slot cutting.
Construction & Mining Equipment: Thick pipe frames and chassis components.
Shipbuilding & Offshore Engineering: Anti-corrosive heavy piping and manifolds.
Oil, Gas & Fluid Pipelines: Multi-bevel welding preparation on high-pressure tubes.
Commercial & Special-Purpose Vehicles: Trailer frames, agricultural equipment brackets.
