METHOD FOR STRENGTHENING SURFACE TREATMENT OF CYLINDRICAL PARTS BY SMOOTHING Russian patent published in 2023 - IPC B24B39/00 

FIELD: material treatment.

SUBSTANCE: hardening treatment of the surface of cylindrical parts by smoothing. Elastic-plastic deformation of the surface of a rotating part is carried out by a smoother with a synthetic diamond indenter by acting on the indenter with a constant radial force and a fixed feed value along the axis of the part with forced cooling of the smoothing working area with a cutting-lubricating process fluid. The synthetic diamond indenter is made with a radius of curvature of 1.5-2.5 mm. Elastoplastic deformation of the surface of a rotating part is carried out in two passes at a constant feed rate of 0.05-0.2 mm. In the first pass, smoothing is carried out with a constant radial force on the indenter of 50-70 N, and in the second pass, smoothing is carried out with a constant radial force on the indenter of 75-130 N.

EFFECT: performance properties of the parts are increased, their reliability and service life are increased.
