Abstract
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.
Claims21
A fixed abrasive article comprising:
- a body comprising a cylindrical shape comprising an upper surface, a bottom surface, a side surface extending between the upper surface and the bottom surface, and a central opening, defining a three-dimensional volume of the body;
- the body having abrasive particles contained within the three-dimensional volume of the body by a bond material extending throughout the three-dimensional volume of the body, the abrasive particles including a plurality of 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 have a predetermined position or a predetermined three-axis orientation;
- wherein the plurality of shaped abrasive particles comprise a first radial set of shaped abrasive particles spaced at a first radial distance from a center of the body;
- wherein the plurality of shaped abrasive particles comprises a second radial set of shaped abrasive particles spaced at a second radial distance from a center of the body that is different than the first radial distance;
- wherein the shaped abrasive particles of the first radial set have a predetermined rotational orientation different than the shaped abrasive particles of the second radial set.
