SPLINE ROLLERS

Spline rolling dies are crucial components in modern manufacturing. They perform a cold-forming process where they are pressed against a blank shaft to create an external spline (gears, serrations, or threads). This method is superior to cutting because it work-hardens the metal, leading to a finished part with increased strength, longer fatigue life, and a smoother surface finish. These dies are essential for producing high-reliability shafts used in applications like automotive transmissions and aerospace machinery.
