A detection unit of a matching apparatus 32 is connected to a control unit 6 of a computer so that a detection signal indicating measured values of diameters of outer and inner ring raceways can be sent thereinto. An outer ring secondary grinding apparatus 24, an cuter ring super finish machining apparatus 25a, an inner ring secondary grinding apparatus 26 and an inner ring super finish machining apparatus 28a are connected to the control unit 6 so that control signals can be received. The control unit 6 imparts shift amounts to diameter machining target values which are set, respectively, in the grinding apparatus 24, 26 and the super finish machining apparatus 25a, 28a for machining a raceway surface of at least one bearing ring of outer and inner rings, based on measured values of diameters of the outer and inner ring raceways which were measured by the detection unit.
