Abstract:
A composite abrasive wheel comprises primary and secondary abrasive portions. The primary abrasive portion comprises shaped ceramic abrasive particles retained in a first organic binder. The secondary abrasive portion is bonded to the primary abrasive portion, and comprises secondary crushed abrasive particles retained in a second organic binder. The primary abrasive portion comprises a larger volume percentage of the shaped ceramic abrasive particles than the secondary abrasive portion. A central aperture extends through the composite abrasive wheel.
