Abstract
A cutting method which can efficiently cut braking surfaces of a brake rotor of a wheel bearing assembly. A reference surface on one side of a vehicle body-mounting flange provided on an outer member of the wheel bearing assembly is brought into abutment with positioning pieces of a positioning member, and a cylindrical outer peripheral surface of the outer member is clamped by a chuck device. By advancing pushrods of first and second pressing devices, a raceway member and a hub ring forming the inner member are pressed axially to put the assembly into an actual mounted state. The inner member and the brake rotor are rotated by rotating the pushrod of the second pressing device, and a cutting tool is moved in a direction parallel to the reference surface to cut the braking surfaces of the brake rotor.
