Bonded abrasive wheel and method of making the same

A method of making a bonded abrasive wheel, the method comprising steps:

• a) disposing a layer of a first curable composition into a mold having a circular mold cavity with a central portion adjacent to a central hub, wherein the circular mold cavity has an outer circumference and a rotational axis extending through the central hub, and wherein the curable composition comprises non-magnetizable abrasive particles dispersed in a first organic binder precursor;
• b) disposing a first porous reinforcing material onto the layer of first curable composition;
• c) disposing a layer of a second curable composition onto the porous reinforcing material and first curable composition, wherein the second curable composition comprises magnetizable abrasive particles dispersed in a second organic binder precursor;
• and
• d) applying a magnetic field to the curable composition such that 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 wherein the magnetizable abrasive particles adjacent to the outer circumference of the circular mold cavity are aligned at an average angle that is from 35 and 90 degrees, inclusive, with respect to the rotational axis;
• and
• e) at least partially curing the curable composition to provide the bonded abrasive wheel.
