Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a brake disc capable of improving the appearance of the brake disc by reducing a raised portion generated as much as possible when performing chamfering by a mold without complicating the mold structure for performing the chamfering of an outer peripheral corner part, and the brake disc.
SOLUTION: The method of manufacturing the brake disc integrally rotating with a wheel is equipped with an outer peripheral press step where the outer peripheral shape of an outer rotor plate 2 of the brake disc is made to be an uneven repeated shape in the radial direction by press forming, and a chamfering step for forming a chamfered surface 6 on the outer rotor plate 2 having a repeated shape by pressing a mold 12 having an inclined surface 12a abutting on a corner part 2d corresponding to the repeated shape and the inclined surface 12a where the inclination angle θ with respect to the mold pushing direction is 10° or more and 30°or less to the corner part 2d of the outer peripheral edge of the outer rotor plate 2 having the repeated shape formed in the outer peripheral press step, and by plastically deforming the corner part 2d.

Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a brake disk, and a brake disk with high practicality, capable of suppressing an increase of manufacturing cost while maintaining desired performance even when a chamfered surface is formed on a corner part of an outer peripheral edge of the disk brake of which an outer peripheral shape repeats radial recesses and ridges. SOLUTION: The manufacturing method of the brake disk includes an outer periphery pressing step for press-forming the outer peripheral shape 5 of a rotor plate 2 of the brake disk 1 into a shape where the radial recesses and ridges 5a, 5b are repeated, and a chamfering step for forming the chamfered surface 6 by pressing a die 7 with a slope surface 7a abutting on a corner part 2d on an outer peripheral edge of the rotor plate 2, and plastically deforming the corner part 2d.
