Economical and precise production of lightweight components

The components processed on Felss rotary swaging machines can be designed with extremely thin walls due to the uninterrupted grain flow and the increase in strength resulting from the rotary swaging process. This makes them particularly light and precise and allows maximum design freedom in the construction.


Forming with simultaneous feeding

The rotary swaging machines in the HA product family consist of two work areas, forming and feeding. The systems work with a hybrid drive: The rotary swaging frequency is generated electrically, while feed movements are generated hydraulically. Different component sizes can be formed with the various machine types (HA16-HA120). The systems are optionally available with and without NC technology or with an additional circulation system for the production of steep transition angles at the ends and in the middle of a workpiece.

Possible component sizes

The component lengths always refer to the pipe, not to the solid material.

  • Pipe length: 25-6,000 mm
  • Finished part length : 30-7.000 mm
  • Workpiece diameter: 0.8-120 mm

Advantages of HA machines

  • High degree of machine customization
  • Fast and efficient production of workpieces
  • Very high repeat accuracy due to tool-based geometries
  • Material savings through non-cutting production
  • Increasing the strength of the component
  • High surface quality of the components
