Resin bonded abrasive tool and method of making the tool
First Claim
1. A resin bonded abrasive tool consisting essentially of abrasive grain and an organic bond, the organic bond comprising a thermosetting resin binder and a precursor filler system capable of forming in situ an active filler system by reacting under the heat generated during grinding.

Abstract
A resin bonded abrasive tool consists of abrasive grain and an organic bond comprising a thermosetting resin, such as epoxy resin, phenolic resin or rubber or blends thereof and a precursor filler system capable of forming in situ an active filler system by reacting under the heat generated during grinding. The organic bond optionally further comprises a filler system. A method of making the resin bonded abrasive tool consists of mixing the abrasive grain and the organic bond with the precursor filler system, pressing the resulting mixture into shape, and curing the abrasive tool at about 150 to 200° C.

15. A method of making a resin bonded abrasive tool having an active filler system consisting of:
-
a) mixing abrasive grain and organic bond comprising a binder and a precursor filler system capable of forming in situ the active filler system by reacting under the heat generated during grinding, to form a uniform mixture; b) pressing the uniform mixture into shape; c) curing the abrasive tool at about 150 to 200°
C.; andd) grinding with the cured abrasive tool at forces sufficient to generate temperatures of about 300°
to 1000°
C. at the grinding interface, and thereby forming the active filler system. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
