FIELD: mechanical engineering.
SUBSTANCE: following preliminary mechanical processing, crank-shaft is subject to induction heating and cooling due to heat conductivity in crank shaft core. As a result, the surface hardness is HRC 34-48. After that the surface is grinded and treated under low temperatures by chemical and thermal methods. Finally, the surface is mechanically processed.
EFFECT: reduced manpower effort during crank shaft production and required durability, strength, reliability, thermal resistance and wear resistance.
