FIELD: manufacturing technology.
SUBSTANCE: invention relates to production of keyed connection on shafts. Key is installed in key slot with clearance. Heating and plastic deformation of the shaft key slot is performed by an electrode-tool for electromechanical processing, which is installed vertically and moves along the key slot along its surface at distance of 0.3…1.5 mm from the slot edge so that the shaft metal is settled and distributed towards the slot side. Metal shaft distribution is restricted with a key.
EFFECT: method provides simultaneous production of tight key connection and strengthening of keyway side surface.
