The five-axis LT-FREE fiber laser machine from BLM cuts, drills, punches and mills mild steel, copper, aluminum, brass, stainless steel and galvanized steel, and can be used for trimming and feature cutting right on the bend, high quality and accurate cuts needed for robot welding later in assembly, trimming or cutting features in hydroformed parts, feature cutting or trimming anywhere on a bent tube with no limit to part access, trimming formed sheet metal parts, and cut features in assembled frames or components.

The five-axis LT-FREE fiber laser machine from BLM Group USA (Wixom, MI) is designed for cutting three-dimensional formed or shaped parts, such as bent tubes, hydroformed tubes, welded assemblies and stamped or flat sheets. The part does not move during the cutting operation because the laser head’s freedom of movement guarantees the highest flexibility and accuracy to produce parts. This machine can make cuts very close to each other for the ability to nestle parts on a single bent tube and then use the laser to separate, saving significant material cost. Traditional cutting, drilling, punching and milling operations, which are normally carried out in sequence on separate machine tools, can now be performed on a single fiber laser machine. This eliminates set up, reduces material handling, eliminates work-in-process inventory and downsizes the space needed for storage.

The LT-FREE series includes the HIGH FLEX universal model for bent and hydroformed tubes, flat and deep-drawn sheets or welded assemblies, the PIECE VALUE model with rotary turntable and automatic load/unload for high productivity machining, and the ENTRY LEVEL model with dual fixed table for a wide variety of part configurations. The fiber laser machine comes with unique software that can be used to create part programming of virtually any complexity in a simple, user friendly, 3D graphical environment. With powers up to 5 kW, table dimensions of 59 in x 39 in and axis stroke to X 116 in, Y 37 in, and Z 29 in, this fiber laser machine is ideal for machining mild steel, copper, aluminum, brass, stainless steel and galvanized steel, and can be used for trimming and feature cutting right on the bend, high quality and accurate cuts that are ideal for welding by robots during a later assembly stage, trimming or cutting features in hydroformed parts, feature cutting or trimming anywhere on a bent tube with no limit to part access, trimming formed sheet metal parts, and cut features in assembled frames or components.
