First Claim
Patent Images
1. A method for dry grinding a workpiece, comprising grinding a workpiece with an abrasive tool comprising a magnesium oxychloride cement bond containing graphite in an amount of at least about 5% by wt. based on the MgO content of the bond and an abrasive material in an amount sufficient to effectively abrade the workpiece.

Abstract
Magnesium oxychloride cement bonds are improved by incorporation of graphite. The graphite not only contributes to cooler dry grinding with abrasive tools based on the magnesium oxychloride bond, but unexpectedly also improves heat strength of the bond.
