Due to the increasing need to rationalize and improve production methods, the thread rolling process has become essential in any modern production facility that wants to operate efficiently. Thread rolling is a cold deformation method in which the material is stressed beyond its elastic limit, thus remaining deformed. During the rolling process, the metal fibers are displaced, but not cut as in the case of thread cutting. In the rolling process, the material is made to flow in an axial direction. In the rolling head, two, three, or more rollers are inclined at an angle corresponding to the spiral angle of the thread to be produced.
