The article presents findings on the distribution of temperature fields during Electromechanical mandreling (EMM) of holes in the surface of the workpiece and the tool. The design temperatures significantly exceed the phase transformation temperatures, but the melting of structural components in the surface layer of the workpiece does not occur due to high cooling rates. It is not possible to fix the maximum process temperatures experimentally due to their short duration of action.
