摘要： Provided are a workpiece feeder for roller end face processing which is capable of feeding a roller to a roller end face processing machine in a stable posture, a roller end face processing machine which is capable of stably and highly accurately processing both end faces of the roller fed by such a workpiece feeder for roller end face processing, and a roller for a rolling bearing processed by such a roller end face processing machine. The workpiece feeder for roller end face processing includes: a carrier ring (23) having a plurality of recesses (22) arranged in a radially-inner surface (21) thereof at a predetermined pitch along a circumferential direction; a regulating wheel (24) fitted into the carrier ring (23) to form roller fitting cavities (65) between a radially-outer surface (24a) of the regulating wheel (24) and the plurality of recesses (22); a carrier support for supporting the carrier ring (23) on a radially-outer side with respect to the plurality of recesses (22); and rotational force applying means (26) for applying a rotational force to the carrier ring (23) on the radially-outer side with respect to the plurality of recesses (22). The plurality of recesses (22) each include an elastic member (35) arranged therein, the elastic member (35) being elastically brought into contact with a radially-outer surface (Wa) of a roller (W) to restrain a posture of the roller.

摘要： It is proposed to improve the efficiency of grinding of a roller end surface of a workpiece for a tapered roller or a convex roller, and to expand the types of workpieces of which end surfaces can be ground to sufficient accuracy. The workpiece (1) is fixed in position by jaws (14) of a retracting mechanical chuck (13) mounted on a spindle head (11) of a five-axis control machining center. The apparent outer diameter of the workpiece (1) is increased by a jig (15). Clamp surfaces (14a) of the jaws (14), and a support surface (15a) of the jig (15) are formed on the machining center. A cutting tool (16) is mounted on a spindle (12) by means of an automatic tool exchanger. The workpiece (1) is rotated about an axis C to cut by turning an end surface of the workpiece (1) to a shape approximate to a predetermined target shape by grinding, which is a spherical surface (S). A grinder (17) is then mounted on the spindle (12) by the automatic tool exchanger, and the position and attitude of the grinder (17) relative to the workpiece (1) are set by five-axis control such that the inclination angle ±, the offset amount e, etc. satisfy a predetermined relationship according to the desired grinding. The grinder (17) is then fed in the Z-axis direction to form the spherical surface (S) by grinding.
