SERRATION
1. What’s serration form rolling C/L dies?
C/L dies for form rolling of serration, spline, and rollet.
2. The parts produced by serration form rolling are used in the places which require the quality
of high preciseness including start motors as well as power transfer of steering systems
and suspension systems.

From rolling Types
- Rollet form rolling
Most of rollet process including rotating axis of all kinds of motors and wheels were changed from processing on shelves to
form rolling processing. Form rolling through the pass form rolling method by special design of dies is possible.
- Serration, Spline form rolling
It produces products which are used as the axis to transfer power. Much higher pressure is required than the chase of thread rolling. And rolling
machines with strong pressure should be selected. Tolerance of key ways should be very small because form rolling affects strong torque.
