Abstract:
The present invention relates to a bonded abrasive article comprising shaped abrasive particles and a bonding medium comprising a vitreous bond, said shaped abrasive particles each comprising a first side and a second side separated by a thickness t, wherein said first side comprises a first face having a perimeter of a first geometric shape, wherein said thickness t is equal to or smaller than the length of the shortest side-related dimension of the particle, wherein the article exhibits at least on a part of its surface a surface profile comprising at least one surface feature wherein said shaped abrasive particles have a largest dimension of about the same order of magnitude or larger as compared to said surface feature. The present invention also relates to a composition for use of the preparation of a bonded abrasive article, to methods of preparing and using the bonded abrasive article and to methods of grinding and providing a workpiece.
