Thread rolling

Thread rolling is a cost-effective production method for larger quantities and for standard threads. Because of the relatively high tooling costs, this method is not, however, economically viable for small production quantities. This chipless cold forming process furthermore has a positive effect on the material’s properties. In contrast to machining methods, such as whirling, cutting, milling and grinding, the material’s natural grain orientation is not destroyed.

Thread rolling has a positive influence on the following physical and technical properties:

Synthetic nuts are particularly well suited for rolled threads. The high flank surface quality of rolled threads and the low friction coefficient of synthetic materials result in a higher efficiency of the finished linear drive. According to DIN 103, the core diameter of rolled trapezoidal screws can be up to 0.15 x P less than that of machined trapezoidal screws (required flow radius at thread rolling tool). Rolled threads can contain a small, production-related groove at the outer diameter of the thread. This does not affect the quality or function of the screw; it merely indicates the production method used.
