For producing dimensionally accurate tube geometries with bending radii up to 1.5xD
→ Maximum bending capacity for tube: 76 x 4 mm (400 N/mm²)
→ Maximum bending capacity for tube: 60 x 60 x 3 mm (400 N/mm²)
→ Maximum bending capacity for tube: 76 x 2.9 mm (stainless steel)
→ Total connected load: 7 kW
→ Tube feed length: 4.5 m

Robust and durable steel construction with a rigid, force-locked joint—no susceptibility to torsion due to split designs such as separate bending head and mandrel carrier. Maintenance-free electromechanical drive of the bending axis. The controller's touch display enables simple and intuitive programming and operation of the machine. After the tube is inserted, it is fixed by the chuck in the carriage, ensuring precise positioning of the tube and thereby allowing the creation of dimensionally accurate tube geometries. Standard features also include a geometry check prior to the bending process: if the bending sequence is started in an incorrect position, the machine will not allow the operation, preventing misoperation. Optional features add convenience and increase productivity and thus the system's efficiency.

Data exchange with the optional TBS-3D tube calculation software (PC version) is via USB stick or FTP access from the computer to the machine control. USB or LAN (RJ45) interfaces are provided as standard. Existing tube geometries can be simply and quickly converted, e.g., via the STEP format.
