Spline Rolling Machines Spline Rolling or Spline Rollers is a high production, economical cold forming process that can be used to form many shapes; including splines, threads, helixes, snap rings and more. The spline rolling process utilizes two opposing forming racks which advance over a cylindrical part under extremely high forces. Advantages of Spline Rolling? Lower Costs - Spline rolling yields the lowest piece cost of any Spline producing process. Spline Rolling Machines have high production rates and have documented uptimes of over 95 percent. Forming racks have a long tool life and can commonly produce 100,000 parts or more between each grind. Forming racks can typically be reground up to five times. Stronger Splines - Rolled splines are produced by moving the material. This displacement method of forming results in improved grain structure and a work hardened Spline surface. As a result, rolled splines are up to 30 percent stronger than cut splines. Improved Surface Finish - A rolled spline has a superior surface finish. Versatility - Spline Rolling Machines can accommodate a variety of tool set-ups. A single machine can roll dozens of different parts with varying spline dimensions.
