<p>A method of machining the inner ring for a conical roller bearing having a plurality of rows for finishing the size of the transfer grooves (14) of the respective bearings without being affected by an irregularity in the size of the diameters of the grooves (14), even if one occurs, so as to maintain a constant assembly gap formed when the bearing is assembled. This method comprises the steps of feeding back the deviation from the objective finishing size of the groove to an in-process control gauge (30) for controlling the grinding of the groove to the converted value to the deviation in the axial direction of the inner ring, simultaneously grinding the small-diameter end face (13) and the large collar surface (12) of the inner ring (10) with collar grinding wheels (41) mounted integrally with end face grinding wheels (42) under the control of the gauge, finishing the grooves (14), and then finishing by grinding the small-diameter end face (13) and the large collar surface (12) of the inner ring.</p> |
