DEVICE FOR ELECTRIC PULSE MACHINING Russian patent published in 2014 - IPC B23H7/12 

FIELD: electricity.

SUBSTANCE: invention is related to electric pulse machining. The device comprises a circular knife, a motor connected with the above knife by its rotation, electric discharge control system, which is coupled functionally to the circular knife and a blank part and provides cutting of a blank part by the circular knife in process of electric pulse machining. For the purpose of the circular knife connection to the motor the device comprises a driving spindle with an opening and inclined surface, at that the electric contactor coupled electrically to the electric discharge control system has outer surface coupled to the above inclined surface.

EFFECT: device allows rotation of the circular knife with simultaneous power supply to it at the lowest permitted speed that stipulates minimum wear and tear of the contactor, at that it provides removal of large-size fragments of material by electric pulse machining with minimum quantity of curs, consumed time and power for manufacturing of a part.
