LT-FREE five-axis laser cutting system for 3D parts

The LT-FREE five-axis laser cutting system developed by BLM GROUP ensures top-notch flexibility and simplicity of use for cutting 3D parts in different shapes. Curved tubes, flat and drawn sheets, hydroformed components or welded assemblies can be pierced and trimmed easily and accurately.

All the complex operations normally needed to fabricate high-quality parts can now be carried out in a single operation that can produce parts that are not even feasible using traditional techniques.

Starting with simple, effective off-line programming, the LT-FREE makes completely finished parts in one step, thus eliminating extra material handlings costs, work in process inventory and the related floor space requirements. LT-FREE is a cost effective, lean process improvement.

The LT-FREE is created for a wide range of different applications, from prototyping to final production, in the automotive, aerospace, motorcycle, household appliance, HVAC, furniture and light construction industries or wherever tubes and tubular assemblies are processed.

Four different system configurations are available to satisfy all application needs:

  • Entry Level is the configuration dedicated to prototyping or job shops wtih low production volumes. The system is equipped with a single table onto which the parts to be processed are placed in a fixture. This configuration is ideal when job quality and simplicity are more important than production cycle time.
  • Mid-Flex is the configuration created for shops where small parts are processed and faster cycle times are required. Two shuttle tables work in split stations allowing optimised cycle times and carry out loading and unloading operations in the background.
  • Piece Value is the system for volume production, particularly for the automotive industry. Equipped with a rotary table, it is ideal for applications requiring high productivity and infrequent tool changes.
  • High Flex is the most complete configuration. It is versatile and high-performing with two independent, robotised tables for maximum flexibility. In addition to sheets and mechanical assemblies, the system can process bent and hydroformed tubes accurately and efficiently. The parts are held in position by the robots during processing with no need for complex fixturing.

The use of 1 or 2 kW fiber lasers (higher power, up to 5 kW, is available as required) allows the LT-FREE to cut a very wide range of materials in an energy-efficient manner with low maintenance costs.

Over a decade of BLM GROUP’s laser cutting experience is made available to users in a cutting parameter database guaranteeing high reliability with all feasible materials and thicknesses.

BLM GROUP’s twenty plus years of laser cutting know how is made available to users in a cutting parameter database that guarantees high reliability in a wide range of material types and and thicknesses.

The LT-FREE is easy to use. With the programming and simulation software, users can easily import 3D assemblies, rapidly identify the components to be processed, automatically generate part programs, graphically simulate the cycle to identify any collisions and modify the program off-line before transferring it to the machine. All this with no unnecessary waste of time. The software package also includes an efficient clamp design module for quickly making fixtures with the LT-FREE system itself.
