The super finishing grindstone and super it finishes, grinding manner

摘要

PURPOSE: To provide a super-finish grinding wheel and a super-finish grinding method capable of mitigating the previous machining accuracy of the super- finishing, achieving the super-finishing grinding of the surface to be ground without damaging the quality in a short time, and reducing the cost for the grinding. ;CONSTITUTION: In a super-finishing grinding wheel 1 which is provided with a semi-circular grinding surface 1a and oscillated in the semi-circular direction of the semi-circular grinding surface 1a to grind the surface Wa to be ground, the elastic modulus of a center part 2 of the grinding wheel to constitute the center part in the semi-circular direction of the semi-circular grinding surface 1a is set to be smaller than the elastic modulus of end parts 3, 3 of the grinding wheel to constitute each end part in the semi-circular direction of the semi-circular grinding surface.;COPYRIGHT: (C)1996,JPO
