FIELD: machine engineering, namely combination methods of working, possibly grinding materials by means of wheels on base of electrically conducting binder.
SUBSTANCE: method is realized by means of special apparatus for controlling process of electrochemical dressing of grinding wheel due to changing electrical parameters of dressing depending upon change of cutting power. Apparatus includes electrical circuit that allows set and keep constant value of electric current density at dressing operation; control circuit tracking cutting power change and according to it changing density value of electric current at dressing; DC source; dressing electrode (cathode). Such apparatus allows set target density value of electric current at dressing wheel and keep stable electric current value in electric circuit at changing resistance of inter-electrode gap and automatically control process of continuous electrochemical dressing of wheel.
EFFECT: enhanced efficiency, improved quality of grinding by such wheel.
