CNC tube end forming machines

Numalliance CNC tube end forming machines are engineered to deliver high precision, repeatability, and productivity in tube-end processing. They perform operations such as flaring, reducing, expanding, and sizing with optimized cycle times and consistent quality output. Designed for demanding industrial environments, these machines ensure accurate control of tube geometries while minimizing manual intervention and reducing scrap rates.

Forming capabilities and operations

The range covers a broad spectrum of end-forming applications, supporting various tube diameters and wall thicknesses. The machines can process both precision tubes and larger structural components, ensuring controlled material deformation without altering mechanical properties.

Specific configurations are dedicated to internal and external end sizing, with typical working ranges up to Ø80 mm. Other models provide forming forces ranging from 3 to 70 tons, meeting a wide variety of requirements in terms of complexity and production rates.

Available technologies and configurations

Numalliance machines feature robust mechanical structures combined with advanced CNC control systems, enabling fast cycle times and high repeatability. Fully electric versions enhance energy efficiency while maintaining superior motion control accuracy.

The machines are designed to facilitate quick tooling changeovers and reduce downtime. Configurations include multi-station systems and masked-time loading solutions, optimizing productivity especially in high-mix, low-volume production environments. An example of a tube end forming machine is the Numaform.

Line integration and automation

CNC tube end forming machines can be integrated into complete production cells together with tube bending machines, robotic systems, and transfer systems. This integration enables the creation of continuous automated production lines that reduce handling operations and improve overall productivity.

Tooling developed in-house ensures full consistency between the machine and the forming process, delivering stable and repeatable performance.

Industry 5.0 and process control

In line with Industry 5.0 principles, Numalliance forming machines incorporate advanced monitoring systems for predictive maintenance, real-time quality control, and efficient management of multi-reference production.

Operator-machine interaction is optimized through digital tools that simplify process control and performance analysis. This approach improves productivity, reduces scrap, and ensures consistently high quality levels.
