BLM Group USA’s LT Fiber automated laser tube cutting machine uses a fiber laser resonator to process highly reflective materials such as brass, copper and aluminum. It also can cut galvanized steel and thin-walled tubes.
According to the company, the fiber laser improves energy efficiency and reduces operating costs compared to a traditional CO2 resonator. Routine resonator maintenance and optical beam alignments also are eliminated.
The laser-cutting system can accommodate tubes as large as 6" (152 mm) in diameter with maximum raw tube lengths ranging from 256" to 335" (6,500 to 8,500 mm), depending on the configuration. A bundle loader and automatic unloader are designed to improve speed and productivity. The system is driven by an Artube programming software package that includes direct import of 3D CAD data, part simulation, cycle-time generation and advanced offline nesting software.
