External forming: High-precision splines made easy
New possibilities for the efficient production of complex components - with our Grob cold forming process and Grob roll forming.
Cold forming
With our Grob cold forming process, we facilitate the production of complex geometries. By dividing the forming effort into numerous small steps, high degrees of forming can be achieved even with high-strength steels. This enables the precise production of ready-to-install splines and makes the process both versatile and effective.
Advantages
- Highest spline quality
- Surface hardening
- No destruction of the material grain flow

Intermittent Forming
With the Grob intermittent forming, we close a technical process gap in forming technology. The process offers you new potentials for the fast and efficient production of complex components. Thanks to our innovative, newly-developed kinematics, splining is feasible without axial feed and with very short spline run-out.
Advantages
- Splining up to one shoulder
- Universally applicable
- Surface roughness Ra 0.4 ~ N5
