C9T-Helix

cold forming machine

In contrast to the conventional C9T cold forming machine, the roller heads of the C9T-Helix model can be swivelled thanks to two additional synchronised CNC axes, allowing helical splines to be generated.

BENEFITS

- Very short forming cycles
- Extremely high process stability
- Versatile usage, very short changeover times
- Ease of service and maintenance
