Abstract:
A superabrasive wheel (100, 200) for mirror finishing comprising:an annular base plate (120, 220) having an annular end surface (121, 221) that is circularly annular about a central axis; and a plurality of superabrasive members (110, 210), each having a radially outer peripheral end surface (111), arranged along a periphery of said annular base plate (120, 220), wherein said superabrasive members are spaced apart at intervals from each other in a circumferential direction around said central axis and are fixed onto said end surface (121, 221) of said base plate (120, 220), wherein each one of said superabrasive members (110, 210) has a quadrilateral plate shape confined to extending along a respective flat plane and is so arranged that said radially outer peripheral end surface (111) is substantially parallel to said central axis, each one of said superabrasive members has a base surface (113) extending along a thickness of said plate shape perpendicularly to said respective flat plane, wherein said base surface is fixed onto said annular end surface (121, 221) of said base plate (120, 220), and said superabrasive members respectively comprise superabrasive grains bonded by a binder of a vitrified bond.
