ABSTRACT:
Vitrified super abrasive grain grinding tool comprised of abrasive grains and first and second fillers bonded together by a vitrified bonding material, wherein the abrasive grains are super abrasive grains, the softening points of the first and second fillers are both higher than an inherent firing temperature of the vitrified bonding material for the super abrasive grains, the first filler is a ceramics which maintains a hollow state before and after firing of the bonding material, and the second filler is a ceramics which exists in a non-hollow state. This grinding tool has a high porosity at a low concentration while utilizing excellent grinding characteristic of super abrasive grains with high grain retention force and little burn mark in dry grinding.
