Primary Applicationcutting

The BLM Group LT Fiber series represents Italian excellence in tube and profile laser cutting, offering specialized solutions for processing round, square, rectangular, and special-section tubes with fiber laser precision. As pioneers in tube laser technology, BLM Group combines decades of manufacturing expertise with advanced automation and software integration.

The LT Fiber lineup includes models from compact LT5.10 for light tube cutting to the powerful LT14 Fiber capable of processing tubes up to 14 inches in diameter and 54 feet in length with weights up to 100 kg/m. All machines feature fiber laser sources from 3kW to 5kW enabling efficient cutting of steel, aluminum, copper, brass, and other reflective materials with reduced operating costs.

Advanced features include automatic beam shaping for optimized cutting across different materials and thicknesses, 3D tilt cutting for weld-prep bevels, smart clamping that adapts pressure based on material type, and an internal suction probe for capturing cutting waste and fumes. The BLMelements software suite comprising ArTube CAD/CAM, PartViewer for cost estimation, and Prometheus for remote monitoring enables complete process integration with ERP systems. Designed for unattended operation with automatic changeovers and material optimization, the LT Fiber series delivers production-ready tube cutting capability.

📝 Editor's Review

Ultimate 5-axis 3D laser cutting system for bent, hydroformed, and pre-assembled components

The LT-FREE breaks the rules of flatbed and standard tube cutting. As a true 5-axis 3D system, it can gracefully carve into pre-bent, hydroformed, or deep-drawn components. Its ability to maneuver around complex 3D geometries eliminates the need for multiple secondary punching or milling operations, defining modern 3D laser fabrication.

Best For: Automotive and aerospace sectors fabricating complex 3D curved profiles and stamped parts
