When close dimensional tolerances are required…
The straightening process consists of using a hydraulic press to “punch” a cylindrical shaped part in specific areas to restore straightness to a specified tolerance. It may also include the use of heat, typically via a tempering oven that heats the parts to a set temperature to relieve any residual stresses that may be present in the microstructure of the material. After the stresses are relieved, parts are again placed into a hydraulic press to “punch” them at various points and put them back into tolerance. The heat and “punch” cycle may need to be repeated several times before the part is restored to the specified tolerance. The straightening process must be completed by a highly trained and skilled operator, generally with many years experience straightening parts.
