CNC tube bending machines

Numalliance CNC tube bending machines are designed for bending metal tubes with a high level of precision, repeatability, and productivity. The range covers bending capacities up to Ø152 mm, with configurations allowing clockwise and counterclockwise bending.

Wide range of capacities and applications

Numalliance solutions are intended for the most demanding industries, including aerospace, aeronautics, automotive, HVAC, and furniture. They enable the bending of tubes from Ø3 mm to Ø152 mm, covering both precision applications for small diameters (brake lines, fuel lines, HVAC) and the production of structural or exhaust components with larger diameters, with the ability to manage complex multi-radius geometries.

Bending technologies and production flexibility

Numalliance CNC bending machines stand out for their versatility and ability to accommodate diverse production requirements. The machines allow bending in one or two directions, with multi-radius configurations and fast tooling changeovers, thereby reducing downtime.

Multi-level versions and solutions integrating technologies from partners such as Eaton Leonard ensure high adaptability to different part geometries. The integration of bending robots also makes it possible to produce complex shapes with a high level of automation and repeatability.

In addition, some solutions enable combined wire and tube forming, expanding production capabilities within the same cell.

Performance and technical advantages

Numalliance CNC tube bending machines ensure high-quality bending, with precise control of radii, angles, and deformation. The machine architecture, often fully electric, helps optimize energy consumption while maintaining high performance.

The robust machine design ensures process stability even during intensive production, while digital programming simplifies changeovers and the management of complex parts.

Integration and automation

The machines can be integrated into complete automated cells with production flow management, automated loading and unloading, and secondary operations. This integration increases productivity, reduces handling, and ensures consistent quality throughout the manufacturing cycle.

Examples of Numalliance CNC tube bending machines include the TE bender, the 3D VB bender, and the 3D Tulip bender.
