PURPOSE:To grind the outer diameter of a work in accord with an axial center of a hole diameter in a highly accurate manner, by sticking a solid body carrying coaxial accuracy in making the hole diameter of the solid body with a through hole diameter as the axial center, and grinding it by means of a centerless OD grinding method. CONSTITUTION:A fine hole diameter 2 is accurately adjusted to a position of the axial center part of a tube 3, while a solid body 4 is filled up in a clearance between a blank 1 and the tube 3 so that an outer diameter 41 of the tube 3 by a hole axis 2 is securable. This solid body is taken out of the tube 3 and set to a centerless grinding device, thus an outer diameter 21 is ground by a grinding wheel 5 and regulating wheel 6. |
