FIELD: process engineering.
SUBSTANCE: invention relates to machine building and may be sued for finishing and surface hardening. Workpiece is subjected to circular surface grinding, machining by grinding wheel and hardening element made up of indenter, and is fed relative to both. Said indenter is made of material with hardness exceeding that of machined surface and brought in strip contact with workpiece. It is arranged extended relative to wheel surface in either side in feed direction. Ultrasound frequency amplitude modulated oscillations are imparted to hardening element.
EFFECT: higher efficiency and quality of processing and hardening.
