- the Konica Canre type rotary diamond dresser 44 and the grinding wheel 26 are moved relative to each other based on the shape of the grinding surface of the grinding wheel 26 and rotate from the outer peripheral center part 42 of the frustoconical base 40 on both sides.
- the crystal orientation (1, 0, 0) surface of the tip side of many octagonal diamond grains 15 protruding outward in the direction perpendicular to the axis is in contact with the grinding wheel 26, for example, grinding wheel 2 Dress both sides and outer peripheral surface of 6 into a straight grinding surface.
- the crystal orientation of the force octagonal diamond grains ((1, 1, 0) in which the angle formed by both walls of the V grooves 3 3 and 4 3 is about 70 degrees.
- the open crystal orientation (1, 1, 1) plane may be bonded to both wall surfaces of the grooves 3 3 and 4 3 by the bonding material 18.
- the V grooves 24, 33, 43 are continuously engraved in the rotational direction. However, the V groove 24 is an outer peripheral portion of the disc-shaped substrate 11.
- V-groove 3 3 is frustoconical base 30 Outer periphery of large diameter end face 3 2, V groove 4 3 is outer circumference of double-sided frustoconical base 40 In the central part 42, both wall surfaces may be formed intermittently in the rotational direction or perpendicular to the rotational direction.
- octagonal diamond grains 15, small-diameter diamond grains 20, and CBN abrasive grains 27 are used as a binder material 18. It may be fixed by electroless plating. Industrial applicability
- the rotary diamond dresser according to the present invention is used as a rotary diamond dresser for dressing a grinding wheel grinding surface in a desired shape with high accuracy in a grinding machine that grinds a workpiece with a rotationally driven grinding wheel. Is suitable.
