<P>PROBLEM TO BE SOLVED: To provide a truing method by which the outer peripheral part of a grinding wheel is formed by effectively utilizing the polishing action of an abrasive grain separated from a truer and by using a simple apparatus that does not require to change the direction of the rotary shaft of the grinding wheel. <P>SOLUTION: When a support 9 for supporting the grinding wheel 6 moves in a direction along each of three axes, namely, an X axis, a Y axis, and a Z axis, the axial center 71 of a rotary shaft 7 always directs toward the Y axis direction. When the outer peripheral part 8 of the grinding wheel 6 is formed by the grinding surface 2 of a truer 1 formed into a conical surface, a positional relationship between the truer 1 and the grinding wheel 6 is maintained in such a manner that a normal at a point P1 on a generating line 5 forming the grinding surface 2 and a normal at a point P21 on the outer peripheral part 8 direct toward the same direction. In other words, a contact part where the point P1 is in contact with the point P21 moves along the generating line 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
