The invention relates to a bearing raceway ultrasonic electrolysis composite forming grinding machining method and device.The machining method comprises the three working steps of rough grinding, accurate grinding and smooth grinding, under the condition that the type and concentration of electrolyte are certain, rough grinding aims at the machining efficiency, large voltage and the duty ratio of 100% are adopted, ultrasonic vibration is not applied, and fine grinding is carried out; the current density in the processing gap is large enough, and the material removal rate is high enough; the fine grinding takes the machining quality as a target, voltage and duty ratio are optimized, and proper ultrasonic vibration is supplemented, so that the electrolytic action and the mechanical action reach the optimal dynamic balance state under the ultrasonic cavitation effect, and the machining quality of the bearing raceway is improved; and on the basis of accurate grinding, ultrasonic vibration is adopted to assist tim
