    摘要： A method of imparting compressive residual stress to a first plurality of balls (16) includes a) placing the balls between a first body (12) having a first surface (14) and a second body (20) having a second surface (22), the first surface including a smooth contact portion, the smooth contact portion being substantially flat or convex and having a surface hardness greater than or equal to an initial surface hardness of the balls, b) imparting a compressive stress along a first diameter of the balls (16) by pressing the first body (12) toward the second body (20) or the second body (20) toward the first body (12) or the first and second bodies toward one another with a force, and c) causing relative movement between the first surface (14) and the second surface (22) while maintaining the force at or above a minimum level to impart the compressive stress along other diameters of the balls (16) different than the first diameter.

    摘要： A green ball (91) grinding method includes the step (S20) of supplying a green ball (91) between a first surface (11) of a first member (10) and a second surface (21) of a second member (20) constituting a grinding apparatus (1), and the step of grinding the green ball (91) between the first surface (11)and the second surface (21) while the green ball (91) rotates around its own axis and in orbital motion. In the step of grinding the green ball (91), the step (S30) of causing the green ball (91) grinding to proceed while applying load between the green ball (91) and each of the first surface (11) and the second surface (21), and the step of modifying the rotation axis of the green ball (91) by reducing the load lower than in the step (S30) of causing the green ball (91) grinding to proceed are executed alternately.
