Axial forming in detail
You benefit from axial forming in many different areas of application: especially for high-quality gear components that require cost-effective production processes. With axial forming, all gear dimensions are specified with the highest precision. As the teeth are an exact copy of the tool, there are basically no pitch errors. The profiles are highly precise and the root radius is completely symmetrical, which significantly increases fatigue strength. Each component is produced in short process times and, in contrast to machining production processes, the strength of the components is increased.
How does axial forming work?
The principle of the patented recursive axial forming process is very simple: a spline tool presses external splines axially into a hollow or solid workpiece. All teeth are formed simultaneously using a single-piece tool, ensuring maximum precision in the forming process.
The forming movement consists of small, repeated forward strokes combined with minimal backward motions. This sequence of feed and return movements reduces the required forming force, making it possible to shape even thin-walled components. At the same time, the lubrication film is continuously renewed throughout the process.
Internal splines can be produced using the same principle. Axial forming, particularly in blind-hole geometries, enables highly precise and economical manufacturing solutions. In summary, recursive forming leads to a robust, efficient, and repeatable production process for complex spline profiles.

More InformationApplications of axial forming
Axial forming enables the precise production of a wide range of profiles and special geometries. This technology allows for the efficient manufacturing of both internal and external splines, blind-hole geometries, and various gearing profiles such as involute splines and straight-sided (serrated) splines. In addition, the process supports the creation of complex custom profiles, including ball tracks, diametral pitch gears, and application-specific geometries tailored to individual requirements.
Advantages of the axial forming procedure
- Highest gear cutting accuracy up to DIN class 5
- Highest quality in terms of pitch error, profile deviation and two-ball dimension
- Two-ball dimension tolerances of up to +/-0.01mm also possible for cm/cmk values
- Highest output of up to 5 parts/minute
