What is Thread Rolling ?

Thread rolling is a method of cold forming in which the material is stressed beyond its elastic limit, thereby forming the material continuously. During the process the grain structure is displaced but not broken enabling the material to flow continuously in an axial direction.

Shown in the 2 Diagrams above is a micro section of the Material Grain Structure of two separate V-Type Threads.

In Figure 2, The Rolled Components Grain Structure is displaced but not broken. That is not the case in Figure 1 where the Thread Cutting Method is applied.
