FIELD: technological processes.
SUBSTANCE: invention is related to the field of metal forming, more precisely, to straightening with simultaneous finishing-strengthening processing by surface plastic deformation of nonrigid shafts. Preliminarily elastic deformation of nonrigid shaft is carried out, as well as straightening with simultaneous surface plastic deformation realised with continuous force of deforming tool moved along generatrix of nonrigid shaft that rotates around its central axis. Besides preliminary elastic deformation of nonrigid shaft is executed by application of transverse force at concave side of item in direction of deforming tool by a certain value. And straightening with simultaneous surface plastic deformation is executed in each cross section of nonrigid shaft with provision of its central rotation axis displacement by value fcommon on section, which is symmetrically installed relative to shaft middle.
EFFECT: improved quality.
