Tube Laser Cutting

3D laser tube cutting machines are revolutionizing the design and production of steel structures. With their efficiency, versatility, and precision, automated systems can achieve results that no traditional method can compete with.

The BLM GROUP offers a wide range of 3D laser cutting machines for tubes, profiles, and beams, handling diameters from 12 mm all the way up to 610 mm.

Modern steel construction allows for the realization of complex architectural projects with the help of 3D laser cutting machines for producing structural components. Today, one finds that even a single component contains various laser-cut details such as slots, holes, bevels, and complex geometric shapes.

Traditionally, manufacturing this kind of complex part required multiple specialized systems and operators. 3D laser cutting does everything in a single operation, eliminating any rework and delivering many times higher precision and quality.

Structural joints of pipes and beams also often necessitate very complex cutting geometries. These geometries are complicated further by difficulties in welding, which are associated with the processing time and the quality of execution of the process.

With 3D laser cutting technology, the notches are defined to a high precision within joint geometry and beveled precisely to the correct angles to ensure penetration in the weld. By using the above advanced connection methods, the structures can be created lighter, and therefore produce lower production costs with high environmental responsibility.

BLM GROUP offers six standard tube laser cutting machines and a combined laser system for processing tubes and sheet metal.

The compact LT 5.10 model is able to cut round, square, and rectangular tubes from 0.5\" to 5\" in diameter using a 2D cutting head. Equipped with the TubeCutter cutting head, the LT 5.10 produces high-quality parts. It has automatic focus and integrated laser parameter management, thus eliminating manual adjustments.

The advanced LT 7 model uses a 3D cutting head to process round, square, and rectangular tubes and open profiles and special sections from 0.5\" to 6\" in diameter. The LT 7 is designed for maximum productivity, with automatic production changeover, so it will be ready to go at the start of the next batch. After each run, the loader, spindle, steady rest, and intermediate supports automatically adjust for the new material, meaning that production does not need to stop.

The LT 8.2 model provides state-of-the-art 3D laser cutting for tubes of round, square, and rectangular shape, as well as open profiles and special sections with diameters from 0.5" to 9.45". The features include two independently positionable loaders with the possibility of bundle, step-by-step, or single bar loading, in front or rear position. Additionally, it gives short part unloading, scrap conveyor, and front and rear motorized tables. The design is versatile so that you can personalize the layout according to the available space and specific needs of your production.

The LT Fiber EVO is a highly successful tube cutting solution, proven by thousands of applications across diverse production environments. This machine uses a 2D cutting head to process a wide range of materials, including round, square, and rectangular tubes, as well as open profiles and special sections, with diameters from 0.5" to 6". Its compact design integrates best-in-class engineering, user-friendly operation, and the flexibility to handle various tube shapes.

Model LT 12 is a powerful 3D laser tube cutting machine that cuts a wide variety of materials and sizes. It is capable of cutting round, square, and rectangular tubes, open profiles, as well as special sections from 0.5\" to a very large diameter of 12\". Scrap efficiency mode is another feature; the unit minimizes material waste. The integrated spindle and chuck design also enables cutting of the very end of the bar, with scrap being only 113 mm.

The LT 14 / LT 24 are tube cutting models built to cut large diameter tubes and thick materials. Capabilities include round, square, rectangular tubes, open profiles, and special sections, with a 3D tube cutter. Their maximum tube diameter is up to 14" or 24". Several key benefits exist when using this technique of laser cutting rather than plasma or oxy-fuel cutting. These benefits include a considerably lower cost per part, better quality of parts, and consistent machining precision that will not require post-processing adjustment. This means saving on time and quality control consistency.

The LC 5 is a versatile combined laser cutting machine that can process both tubes and sheet metal. It accommodates sheet sizes up to 236" x 79" and tubes with diameters up to 4.72", with a bundle loading length of up to 21".

A key advantage of the LC 5 is that it can switch between tube and sheet processing without any reconfiguration or retooling. This maximizes production time and optimizes your investment by ensuring continuous operation.

BLM GROUP also offers proprietary tube cutting software, ArTUBE. This CAD/CAM software is designed for drawing, manipulating, and designing tubular parts, streamlining the process from initial concept to finished part program in just a few clicks.

ArTUBE is a complete CAD/CAM solution that is dynamic as well as flexible to customer needs. With over 20 years of experience, it has been focused on dedicated tube processing for users, allowing them to have a wider range of technological options while having the most attention given to detail.

Easy usage is a very important parameter of effectiveness of the tool. ArTUBE provides both powerful performance and an intuitive user interface for making the part design experience efficient and convenient. The users can set options directly from the drawing environment in order to optimize the workflow, achieve the best cutting quality possible, and utilize synergy between ArTUBE and BLM GROUP machinery.

ArTUBE also saves precious time due to automation and sophisticated AI. It can import 3D files and with a single click generate the respective part programs easily. The workflows are simplified and also allow part re-engineering due to the integration of laser cutting and tube bending within one application.
