The invention belongs to the field of electrochemical machining, and specifically discloses a metal piece microstructure abrasive jet electrochemical machining system and method. The system comprisesa rack, a three-dimensional numerical control machine tool, an abrasive jet device, and an electrolyte supply device, wherein the rack is used for fixing the three-dimensional numerical control machine tool; the three-dimensional numerical control machine tool is used for fixing a metal piece and the abrasive jet device; and the abrasive jet device comprises a spray head unit, a tubular electrode,and a programmable pulse power source. The method comprises the following steps of: adjusting a relative position between the metal piece and the abrasive jet device, performing microstructure abrasive jet machining on a surface coating of the metal piece, then turning on the programmable pulse power source, and performing microstructure abrasive electrochemical machining on the metal piece without the surface coating.
