FIELD: hardening tool.
SUBSTANCE: tool comprises a body with a working reinforcing element in the form of a sphere made with possibility of free rotation in a mandrel in a lubricating fluid flow. Sphere is separated from the mandrel surface by a layer of lubricating liquid at implementation of the above axial force. Mandrel is made with longitudinal lubrication channels, preventing shutoff of lubricant supply to sphere-mandrel contact zone and to sphere-hardened surface contact zone at application of said pulse action.
EFFECT: as a result, partial removal of residual stresses is provided with increase in strength and reduction of surface roughness of the processed part.
