Mfg. of Spline/Serration Rolling Dies for:

• Saving of material since no material is removed.
• Production is much faster than hobbing and some cases 1/10th of hobbing time.
• Small blank diameter is taken and rolled into bigger diameter. Hence, material saving.
• Since it is a cold forged process, the strength of the Spline increases, thereby increasing life of the rolled component.
• Because of cold forging, smaller cross section can transmit more torque than machined Splines.
• The tool life is very high. Therefore, job consistency is very high compared to hobbing. Hob requires re-sharpening frequently, most of the times after 400 pieces, whereas a Spline Roll can give several thousand pieces before regrinding. In several cases, the life of the Spline Roll is 200 times that of hob life.
• Hobbed Splines have scallops. Therefore, OPD is measured on the high point of scallops but not on maximum area of conduct.
• The surface finish of the rolled flanks is extremely high, even better than grinding finish, because of burnishing effect.
• Greater consistency leading to less rejection.
• Component surface hardness increases. Therefore, rolled component has better life and simple heat treatment like induction hardening is only required for the finished product.
