ABSTRACT:
A method for making abrasive articles uses a soft, easily deformable and flexible preform having a high binder content. The binder gives the preform its integrity, and is present in greater quantity than the retaining powder. The preform can have superabrasive particles mixed therein, or added later. The preform allows even distribution of a small quantity of retaining powder for thin superabrasive articles. A porous layer may be added to the assembly for making an abrasive article, the porous layer absorbing the liquid binder, supporting the retaining powder and superabrasive particles to prevent lateral movement, and perhaps giving strength to the preform. The final assembly to be heated or sintered (preferably under pressure) for making the abrasive article, which may include any number of layers of superabrasive particles, porous layers and preforms.
