The subject application relates to bonded abrasive with low wetting bond material. An abrasive article including a bonded abrasive body having a particular MOR/EMOD ratio associated with a particular bond vol %. The body also can include a) an average Bond Post Area (BPA) of not greater than microns; b) an average Bond Post Count (BPC) of at least 140 per 1536 mm; c) an average bond wetting radius of at least 30/microns; or d) a combination of a) and b).

Bonded abrasive with low wetting bond material

An abrasive article can include a body including abrasive particles contained in the body and ceramic particles contained within a bond material. The ceramic particles can have an average particle size D50c of at least 2 microns and at most 75 microns. The abrasive particles can include an average particle size D50a greater than the average particle size D50c.

Abrasive articles and methods for forming same

A fixed abrasive article having a body including abrasive particles contained within a bond material, the abrasive particles including shaped abrasive particles or elongated abrasive particles having an aspect ratio of length:width of at least 1.1:1, each of the shaped abrasive particles or elongated abrasive particles having a predetermined position or a predetermined three-axis orientation.

Fixed abrasive articles and methods of forming same

An abrasive article including a bonded abrasive body having a certain Homogeneity Factor and a multimodal distribution of abrasive particle sizes where the particles size of a first mode is no greater than 80% of a particle size of a second mode. The bonded body can also have a consistent hardness throughout the body.

An abrasive article including a bonded abrasive having a body of a diameter of at least 260 mm and a volume of at least 20 cubic centimeters, the body also having a bond material including an inorganic material, abrasive particles having an abrasive particle size of at least 40 microns contained in the bond material, and a certain Homogeneity Factor.

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.

An abrasive article including a bonded abrasive body having a bond material including an inorganic material, abrasive particles contained within the bond material of the bonded abrasive body, porosity within a range of at least 55 vol % to not greater than 90 vol % for a total volume of the bonded abrasive body, and a Solid Phase Variation of not greater than 45%.

Various shaped abrasive particles are disclosed. Each shaped abrasive particle includes a body having at least one major surface and a side surface extending from the major surface.
