Claims

[Scope of Claim for Utility Model Registration] (1) A plurality of abrasive grain layers are formed in the shape of thin disks and are made by dispersing superabrasive grains in a metal plating layer along the axial direction, and the above-mentioned axial line Grooves are formed on both side surfaces in the direction, each extending inward from the outer peripheral edge and having a depth in the axial direction that is 3/10 or less of the total thickness in the axial direction. Electroformed thin-edged whetstone. (2) The electroformed thin blade grindstone according to claim 1, wherein the width of the groove is 0.02 to 2.0 mm. (3) The electroformed thin blade grindstone according to claim 1 or 2, wherein the groove is formed on the side surface with the radial direction directed from the outer peripheral edge toward the axis. (4) The scope of the utility model registration claim, characterized in that the groove is formed on the side surface so as to be inclined inward from the outer peripheral edge at an acute angle in the direction of rotation with respect to the radial direction. Paragraph 1 or 2
Electroformed thin-edged whetstone described in section. (5) The above-mentioned groove is spirally formed inward from the outer periphery of the side surface, as claimed in claim 1 or 2 of the utility model registration claim.
Electroformed thin-edged whetstone described in section. (6) A utility model characterized in that the plurality of abrasive grain layers are formed by abrasive grain layers in which the metal plating layer gradually becomes softer from the central part in the axial direction toward both sides. An electroformed thin blade grindstone according to registered claims 1, 2, 3, 4, or 5. (7) The plurality of abrasive grain layers are formed by abrasive grain layers in which the content of superabrasive grains in the metal plating layer gradually decreases from the central part in the axial direction toward both sides. An electroformed thin blade grindstone according to claim 1, 2, 3, 4, or 5 of the utility model registration claim, characterized in that: (8) The plurality of abrasive grain layers are formed by abrasive grain layers in which the superabrasive grains in the metal plating layer gradually become softer from the central part to both sides in the axial direction. An electroformed thin blade grindstone according to claim 1, 2, 3, 4, or 5 of the claimed utility model registration. (9) The plurality of abrasive grain layers are formed by abrasive grain layers in which the particle size of the superabrasive grains in the metal plating layer gradually decreases from the central part in the axial direction to both sides. An electroformed thin blade grindstone according to claim 1, 2, 3, 4, or 5 of the utility model registration claim, which is characterized by:
