Abstract
A brake disk producing method, comprising a periphery pressing step for forming an outer peripheral shape (5) of a rotor plate (2) into a peripheral shape having recesses and ridges (5a, 5b) repeated in a radial direction, and a chamfering step for forming a chamfered surface (6) by pressing, against a corner portion (2d) on an outer peripheral edge of the rotor plate (2), a die (7), and a brake disk made by the method. Accordingly, it is possible to improve heat radiation capability, reduce the weight and moment of inertia, improve safety in handling, and suppress increase in production costs. Furthermore, by forming the chamfered surface (6), the amount of wear of a brake pad pressed by the brake disk (1) can be reduced, and durability of braking performance can be maintained or improved.
