Precision machining method and system for superhard abrasive grinding tool

The precision machining method is characterized in that an abrasive material working layer of an abrasive cutting wheel and an electrolytic grinding tool are respectively connected with a positive electrode and a negative electrode of an electrolytic power supply, and electrolyte is introduced between the abrasive material working layer of the abrasive cutting wheel and the electrolytic grinding tool; the abrasive material working layer of the abrasive cutting wheel and the electrolytic grinding tools form an electrolytic loop through electrolyte, the abrasive cutting wheel rotates, and the two electrolytic grinding tools synchronously servo and oppositely feed to machine the double side faces of the abrasive material working layer of the abrasive cutting wheel; the laser displacement sensor arranged on the side face of the abrasive cutting wheel abrasive working layer is used for monitoring displacement information of the abrasive cutting wheel abrasive working layer relative to the displacement sensor in re
