PROCESS
Cold forming sheet metal
The GROB cold forming process is based on a straightforward and universally applicable principle: the total forming effort needed is broken down into numerous forming increments spread along the entire cylindrical length of the zone being formed.
Benefits
- Very short forming cycles
- Affordable tooling costs
- Superior spline and gear quality
- Surface work-hardening
- Ability to form high-strength steels
- Compensation for the elastic recovery behaviour of the material
