摘要： An abrasive article can include a body including a plurality of portions including a first abrasive portion and a second abrasive portion. The first abrasive portion can include a vitreous bond material and abrasive particles contained within the bond material. The second abrasive particles can include an organic bond material and abrasive particles contained within the bond material. The body can have a burst speed of at least 65 m/s. In an embodiment, the abrasive article can include an interior portion coupled to the first and second abrasive portions. In another embodiment, the interior portion can optionally include abrasive particles or a filler material.

摘要： An abrasive article can include a body including a first portion coupled to a second portion in a radial plane. The body can include a central opening extending in an axial direction of the body through the first portion and through the second portion. The central opening can include a circumferential surface defining an inner diameter of the body. The circumferential surface can be defined by at least a portion of the first portion and at least a portion of the second portion. The first portion can include first abrasive particles contained within a first bond material, including an inorganic material, and the second portion can include second abrasive particles contained within a second bond material, including an organic material. The organic material can include epoxy. In an embodiment, the second portion comprises an elongation-at-fracture of less than 2.7%, a Stiffness Value of at least 8.3, or a combination thereof.
