  • Rotary dresser and manufacturing method therefor
    Patent number: 9770802
    Abstract: A rotary dresser includes a cored bar, an electroformed layer, and superabrasive grains fixed to an outer circumferential surface of the electroformed layer, and a plurality of island regions in which a plurality of superabrasive grains is gathered is provided at certain intervals. Since a plurality of the island regions in which a plurality of the superabrasive grains is gathered is provided at certain intervals, the same degree of dressing accuracy can be obtained as in a case in which expensive large superabrasive grains are fixed at a low density using cheap and small superabrasive grains, it is possible to decrease the contact area of a single superabrasive grain, and favorable cutting quality can be obtained.
