High-performance LT7 fibre laser system for handling tubes and sections with 3D cutting head; this solution is ideal for round, square and rectangular tubes, special and open sections, carbon steel and “premium” materials like stainless steel, copper and aluminium.

No matter what kind of tube we are dealing with, the cutting process always delivers the best possible results in terms of both productivity and reliability. Intermediate supports featuring specific shapes that automatically adjust to suit the tube due to be cut mean that there is additional guiding and containment at the sides when processing light and flexible tubes, resulting in effective handling during fast and sudden rotation.

Cutting-edge support devices on the workpiece feed and unloading line help the tube through the machine at all times, reducing axial deformation in tubes and helping maintain processing accuracy.

STL creates the finished piece in a single phase, avoiding intermediate movements, waiting times, and possible replacement errors.
 
To produce large batches quickly, the bars are loaded one after the other without interruptions.
If you have to deal with small batches and frequent production changes, the LT8.20 will configure itself automatically, in order to maintain continuous production without slowdowns.

With any material and thickness, with closed or open profiles, 2D or 3D cutting possibility, up to max. 45°.

LT12 is a tube and section laser cutting system offering impressive cutting performance across a broad range of diameters and cross-sections, featuring a fibre optic source, which allows it to handle simple metals like carbon steel, as well as galvanized materials, in addition to more premium and reflective metals, including stainless steel, aluminium, copper and brass.

In its standard configuration, the LT12 has a tilt axis (± 45°) designed for 3D cutting that is not at a right angle to the tube surface (bevel). This 3D profiling is a useful option on thicker tubes.

The system is equipped with a chain loader for tubes up to 12.5 meters in length, and a discharge system, also up to 12.5 meters, with a dedicated conveyor for short pieces.

The LT12 features the innovative “Drill & Tap” system, which allows laser cutting, drilling, and tapping of holes to be performed within the same machine.

The cutting head can work both perpendicular and at an angle to the tube surface. The latter method — so-called 3D cutting or bevel cutting — is used to produce bevels with or without a root face, which is a great advantage when dealing with parts that need to be welded.
Throughout the process (loading, cutting and unloading), the bars and sections loaded into the machine are constantly supported as they are transferred from one surface to another. This limits any deformation and, above all, ensures that the cut part gets to its destination without being suddenly dropped, which could compromise its integrity and/or damage the part in question. Larger and thicker tubes traditionally feature some degree of static deformation or misshapen profiles as a result of the original production process. A RENISHAW probe measures the profile, detects centring and torsion errors and allows the machine to compensate and adjust cutting trajectories on the fly to achieve accurate geometries per the relevant drawings and programs.
