Thread Rolling

Why use thread rolling?

Production is estimated to be 10 times quicker, cleaner and more efficient:

 

  • accuracy of the thread profile is excellent

  • tensile strength is greatly increased

  • higher quality surface finish

  • superior wear resistance

  • greater resistance to fatigue

  • increased resistance to corrosion

  • simple operation in terms of repetitions

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 two 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.
