Cold forming / rolling of solid material

The GROB cold forming process is based on a straightforward and universally applicable fundamental principle: the total forming effort needed to generate splines in solid materials is broken down into numerous forming steps spread along the entire cylindrical length of the zone to be formed. This means that the forces needed to achieve superior forming rates and high degrees of deformation are comparatively low, allowing ready-to-install precision spline geometries to be produced. As its name implies, this technique applied is a strictly forming (rolling) process during which no chip forming is involved.
