Abstract: An outer member and an inner member constituting a wheel bearing device are assembled and the brake rotor is fixed to the hub ring of the inner member. In this state, the pad slide surfaces of the brake rotor are lathed with the reference provided by a wheel pilot end surface. Alternatively, the wheel pilot end surface of the hub ring by chucking the knuckle pilot of the outer member with the wheel bearing device put in its assembled state, and the pad slide surfaces of the brake rotor are lathed with the reference provided by the wheel pilot end surface.

Abstract: A processing method for a bearing is capable of shortening a lead time without the need for carrying out super finishing (mirror grinding). A component of a bearing is finished while chucking the component by a chucking device. Hardened steel cutting and grinding are carried out while chucking the component without releasing the chucking by the chucking device.

Abstract: A brake disk braking surface processing device 1 includes a rotation driving device 11 that rotates a brake disk 2, a processing section 12 that processes braking surfaces 4 and 5 of the brake disk 2, and pressing rollers 13 and 14 that press the braking surfaces 4 and 5 of the brake disk 2. The brake disk braking surface processing device 1 includes the pressing rollers 13 and 14 that press the braking surfaces 4 and 5 of the brake disk 2. Therefore, even when tools are pressed against the braking surfaces 4 and 5 in a direction perpendicular to the braking surfaces 4 and 5, deformation of the braking surfaces 4 and 5 of the brake disk 2 can be suppressed with certainty. As a result, processing accuracy of the braking surfaces 4 and 5 of the brake disk 2 can be enhanced.

Abstract: Provided is a method of manufacturing a bearing device for a wheel provided with: a hub wheel (2) having a flange (1) extending radially outward; a constant-speed universal joint (4) having an outer joint member (3) fixed to the hub wheel (2) ; an external member (5) disposed on outer periphery sides of the hub wheel (2) and the outer joint member (3); and rolling bodies (6) interposed between the external member (5) and the hub wheel (2) and between the external member (5) and the outer joint member (3), respectively. The method includes: assembling the hub wheel (2), the constant-speed universal joint (4), the external member (5), and the rolling bodies (6) to produce a subassembly body (S); and machining a mounting surface (21) of the flange (1) of the hub wheel (2) to which a brake rotor is attached, while the hub wheel (2) and the outer joint member (3) are rotated about an axis (O) of the subassembly body (S) with the external member (5) of the subassembly body (S) being fixed.
