PROBLEM TO BE SOLVED: To provide a bond abrasive article having a high efficiency and long life.SOLUTION: An abrasive article comprises a body including abrasive grains included in binders including a metal. The body has: a ratio of V/Vbeing at least 1.5, where Vis a volume percent of particulate materials including abrasive grains and fillers, per a whole volume of the body binders, and Vis a volume percent of binders, per a whole volume of the body; and an average fracture toughness of the binders (K) being 4.0 MPa mor less.SELECTED DRAWING: Figure 1 |
