#12 - The technological leap in tube bending: electric bending machines and 9-axis CNC systems

The electrical revolution in tube bending

Technological progress in the tube bending sector has reached a new level thanks to the irruption of the new electric bending machines and the 9-axis CNC systems. These innovations enable companies such as CORVATS ESPECIALS SL (COES), in Terrassa (Barcelona), to offer more precise, efficient and sustainable solutions for metal tube forming.

Electric bending machines eliminate dependence on hydraulic systems, reducing energy consumption and improving process repeatability. In addition, their integration with multi-axis CNC software enables highly complex simultaneous movements, adapted to customized designs and minimum tolerances.

Key advantages of CNC electric bending machines

• Greater precision and digital control.
• Lower maintenance and energy consumption.
• Ability to work with different materials and thicknesses.
• Integration with 3D simulators to preview results.

At COES, These technologies are applied in sectors such as automotive, aeronautics, energy or industrial furniture, guaranteeing perfect geometries even in small radii.

9-axis CNC technology: total process control

The 9-axis CNC system makes it possible to coordinate the turning, pushing and bending of the tube with synchronized movements. This results in faster production, less waste and consistent quality. Programs are stored digitally, ensuring traceability and repeatability in long series.

Innovation at the service of the industry

The technological leap not only improves productivity, but also opens the door to new designs and applications that would have been impossible a few years ago. COES remains committed to continuous innovation, maintaining its commitment to the technical precision and flexibility that characterize its more than 40 years of experience.

Applications and sectors

These solutions are applied in industrial bending projects for:

• Automotive and transportation.
• Aeronautical and railway components.
• Energy and HVAC infrastructures.
• Technical furniture and metallic structures.

Frequently Asked Questions

What is the difference between an electric and a hydraulic bending machine?

The electric ones use servomotors instead of hydraulic systems, offering higher precision and lower energy consumption. They also eliminate the risk of leakage and allow more advanced and cleaner programming for demanding industrial environments.

What are the advantages of the 9-axis CNC control?

It allows coordinating all tube movements in real time, guaranteeing perfect radii and absolute repeatability in every production cycle. It is ideal for highly complex projects or three-dimensional geometries.

What materials can be bent with this technology?

Stainless steel, aluminum, copper, brass and other ferrous or non-ferrous metals. COES technology allows to adapt to variable diameters and thicknesses without losing precision.

Can CNC bending be applied to custom projects?

Yes, the CNC system allows the process to be parameterized according to the customer's design, optimizing times and reducing manufacturing errors. Ideal for short series or industrial prototypes.

Where does COES operate?

From Terrassa (Barcelona), COES works with national and international customers, offering solutions in tube bending, forming and welding.
