DEVICE FOR SURFACE STRENGTHENING OF CYLINDRICAL PARTS Russian patent published in 2017 - IPC B24B39/04 

FIELD: machine engineering.

SUBSTANCE: device contains an electric motor, a V-belt drive and a deforming roller that are mounted on the support of the lathe and are mounted on the frame with the ability to rotate about an axis perpendicular to the plane of mentioned support. The deforming roller consists of four zones: an entrance zone with a cone angle α= 6-8°, A conical calibrated zone of width b=(0.1-0.2)D with a cone angle where h is the height of the conical calibrated zone, d and D are the diameters of the bases of the conical calibrated zone, the cone α₁=1-3° and exit zone with an angle α₂=30-40°.

EFFECT: improved quality of machined surface.
