PROBLEM TO BE SOLVED: To machine a spherical body to have accurate sphericity by forming guiding grooves having different depths in at least one of fixed and rotary boards. ;SOLUTION: For the spherical body grinding board 1, a spherical body 7 is ground and machined between a fixed board 1 and a rotary board having a plurality of concentric circular guiding grooves 6a and 5a for guiding a spherical body. On at least one of the fixed and rotary boards 6 and 5, guiding grooves 6a and 5a having different depths are formed. Accordingly, since the guiding grooves having different depths are formed on at least one of the fixed and rotary boards, by properly setting the depths of the guiding grooves, a difference in grinding amounts between spherical bodies to be machined is reduced in one spherical body machining process from the receiving of the spherical bodies to be machined to the discharging thereof, and accurate machining is provided to mutual diameter dimension difference in a lot. Also, by similarly setting the depths of the guiding grooves properly, contact angles between the spherical bodies to be machined and the guiding grooves are changed from groove to groove, and thus each of the spherical body is machined to have accurate sphericity.;COPYRIGHT: (C)1999,JPO
