Abstract
A bonded abrasive wheel comprises magnetizable abrasive particles retained in an organic binder. The bonded abrasive wheel has a central portion adjacent to a central hub, an outer circumference and a rotational axis extending through the central hub. The magnetizable abrasive particles adjacent to the central hub are aligned at an average angle of less than 35 degrees with respect to the rotational axis, and the magnetizable abrasive particles adjacent to the outer circumference of the bonded abrasive wheel are aligned at an average angle that is from 35 and 90 degrees, inclusive, with respect to the rotational axis. Methods of making a bonded abrasive wheel are also disclosed.
