The invention discloses an unequal-area uniform grinding method for double end faces of a bearing ring, and relates to the technical field of machining. In order to solve the problems that when the double end faces of the bearing ring are ground at the same time at present, due to the fact that the area difference of the two end faces is too large, the grinding amount of a small end face after grinding is large, and the grinding areas of the two end faces are unequal, eccentric wear is formed, the size of the machined bearing ring has large deviation, the machining quality of products is poor, and the machining efficiency is low. The algorithm is used for calculating the rotating speed of the upper grinding wheel disc, the rotating speed of the lower grinding wheel disc and the rotating speed of the inner pin ring, parameters are input into a high-precision double-end-face grinding machine AC1200F, and therefore the double-end-face unequal-area grinding machining of the bearing ring can be achieved, then appr
