Zusammenfassung: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.
