Claims

[Claims for Utility Model Registration] (1) A plurality of i7s having openings on the outer periphery of the grinding wheel are arranged in a radial pattern on both sides of the abrasive grain layer 2 on the outer edge of the circular substrate 1 of the grinding wheel. A cylindrical whetstone made by coaxially stacking multiple thin whetstones, making them valley, and then resintering them to integrate them.
(2) The cylindrical grindstone according to claim 1, in which the grooves 7 described in paragraph 1 are arranged out of phase with each other on the front and back surfaces of the abrasive grain layer 2. (3) When the thickness of the abrasive grain layer 2 described in item 1 is made 2 times thicker than the thickness of the substrate 1, and the grindstones are overlapped, the space 6 formed is a hole formed on the side surface of the substrate 1. The cylindrical grindstone according to claim 1 of the utility model registration claim, wherein the cylindrical grindstone has a structure in which the groove 7 and the groove 7 constitute a coolant passage.
