FIELD: machine engineering, possibly surface hardening of steel and cast iron parts subjected to intensive wear.
SUBSTANCE: method is realized by means of tool having body in the form of main and additional discs mounted on boss. Said discs are made of material with low heat conductivity factor and with working surface on their periphery. There are recesses in the form of radial grooves on working surface of main disc; there are dents of working surface of additional disc. Length of recess of main disc is equal to 1.5 - 2.5 width values of its working surface.
EFFECT: enhanced quality of working due to formation on surface of worked blank structure of while layers with increased rigidity at using simple tool.
