<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a superfinishing grinding wheel for grinding the raceway of the outer ring of a rolling bearing which enables accurate superfinishing from the first after the replacement of the grinding wheel, a superfinishing grinding wheel manufactured by the method, and a method of super-finishing a rolling bearing. <P>SOLUTION: In this method of manufacturing a superfinishing grinding wheel for machining the raceway of the outer ring of a rolling bearing which is formed of a rotary dresser 50, while the centerline Y of the superfinishing grinding wheel is offset to an orthogonal line X orthogonal to the center axis O of the rotary dresser 50, a plunge machining in which the superfinishing grinding wheel is formed by pressing the distal end 11 of the superfinishing grinding wheel against the rotary dresser 50 is performed at least twice to form curved surfaces 12a, 12b on one and the other sides of the distal end 11, respectively, so as to form a sharp crest part 13. <P>COPYRIGHT: (C)2013,JPO&INPIT |
