Cold forming of solid material parts ERNST GROB AG

The GROB coldrolling machines are robust, and they are designed on the modular principle so as to ensure vibration damping. The roller head carrier is an over-dimensioned cast iron structure. The same applies to the rigid ribbed machine bed, which is fitted with integrally bonded, hardened and ground guideways on which the workpiece carriage is traversed. The traversing motion of the workpiece carriage is actuated via a hardened and ground recirculating roller spindle, which has a particularly high carrying capacity. All the gearwheels, roller head bodies and slides are hardened and ground. Advantages: High flexibilty, short cycle times, low tooling cost, high quality of splines, very stable process Coldrolling machine types: GROB Coldrolling machine 12-NCT / C6 / C9 / C9T.
