Screw Threads through rolling

Rolling is a process that operates through the cold plastic deformation of the material and let the obtaining of precision threads and profiles.
Advantages of this type of working:

    high quality in material
  • More resistance due to the fact that the material, through rolling, doesn’t suffer the incision of its fibres but modifies the crystal structure, creating an excellent security against breakages.


  • resistance
  • More resistance to wear, because rolling with the deformation causes the smoothing of the surface with a reduction of wear and noise, which besides permits a smaller working stress.


  • precision
  • Great repeatability due to the fact that using rough material with the right requested tolerances, it is possible to obtain very precise threads.
