Precise solutions for complex tube geometries
The Combined Bending Center (CBC) machines from Felss stand for precise and flexible tube bending. Thanks to their modular design, different bending processes – such as rotary-draw, roll, push-roll or collet bending – can be used individually or in combination. This enables the production of complex tube geometries with short straight sections between bends.

The Process: Tube Bending
With Felss tube bending, tube sections are automatically fed into a CNC-controlled machine and then bent. The bending head can reproduce various bending processes, making it possible to realise a wide range of tube geometries on a single system. Applications include fuel and brake lines as well as heat exchanger tubes.
Flexible in Compact and Classic
The CBC series is available in two versions – Compact and Classic. Both are based on the same modular principle, but differ in their focus:
- CBC Compact – ideal when fast commissioning and a small footprint are required. The integrated control cabinet makes the machine particularly space-saving, while standard assemblies ensure straightforward configuration.
- CBC Classic – designed for more complex tasks. It meets extensive specifications and allows interlinking with further processes such as end forming, washing or measuring tasks.
Together, the CBC family covers a wide range – from space-saving stand-alone machines to fully integrated production cells. This ensures that every production requirement can be met without compromising on precision or bending quality.
Advantages of tube bending machines
- Highest bending quality thanks to maximum tube circumference
- Minimised tube collapse thanks to special tool geometry
- Small radius-to-diameter ratios without the use of a bending mandrel
- Complex pipe geometries with short straight lengths between the bends
- Roll, draw, push-roll and collet bending possible
- Left and right-hand bending, multiple bending planes and bending radii in one tool
- Operation via graphical user interface including 3D visualisation of the bending process
Possible component sizes
- Tube diameter: 3.2 x 0.7 to 12 x 1.5 mm
- Free tube length: approx. 90-1,200 mm (optionally up to 1,500 mm)
Complex lines in perfect shape
Whether common rail, brake or fuel lines: CBC machines bend complex geometries with precision and repeatability. The result is components that integrate seamlessly into demanding systems.
