Thread rolling is a metal forging process that forms threads on cylindrical blanks without removing material, using hardened steel roller dies with negative thread profiles. High pressure displaces the material, creating threads through deformation instead of cutting. This enhances thread strength and hardness due to cold working, yielding a better surface finish and dimensional accuracy than cut threads. Efficient for mass production, it’s ideal for industries like automotive, aerospace, and construction, where precision and strength are vital. Despite higher initial setup costs due to specialized equipment and tooling, it excels in producing external threads on cylindrical parts, while internal threads may require additional processes.
