Universal shafts come in many different styles and types and their field of application is the transmission of power.

For universal shafts, careful preparation of the hardening process is a key point of success.

The hardening process is preceded by soft turning and milling, where the challenge is often to maintain tight tolerance dimensions. Careful preparation of the hardening section maintains a smooth turning process for hard parts.

Predictable production and excellent surface finish are particularly important in the turning of hard components. In addition to all this, high economic efficiency must also be guaranteed.
