Abstract:
1. A processing method for cutting pad slide surfaces of a brake rotor of a brake rotor-equipped wheel bearing device, the brake rotor-equipped wheel bearing device including an outer member having a car body attaching flange in an outer periphery and two rows of raceways in an inner periphery, an inner member including a hub ring having a wheel attaching flange in an outer periphery, one row of raceways and a small diameter section, an inner ring disposed in the small diameter section of the hub ring and having one row of raceways, two rows of rolling elements, one row of the two rows of rolling elements being interposed between one of the two rows of raceways of the outer member and the one row of raceways of the inner ring and the other row of the two rows of rolling elements interposed between the other of the two rows of raceways of the outer member and the one row of raceways of the hub ring for relatively rotatably supporting the outer member and the hub ring, and a brake rotor fixed to the wheel attaching flange of the hub ring, said processing method comprising: lathing a wheel pilot end surface of the hub ring by chucking a knuckle pilot outer diameter of the outer member with the wheel bearing device in an assembled state, and lathing the pad slide surfaces of the brake rotor with a reference provided by the wheel pilot end surface of the hub ring.
