Glass-bonded super abrasive grinding wheel

Abstract

The objective of this invention is to provide a glass-bonded superabrasive grinding wheel with excellent grinding performance. The glass-bonded superabrasive grinding wheel of this invention comprises a superabrasive layer containing diamond abrasive, a glass bond, and a filler, wherein the filler comprises alumina. The glass bond comprises Si, Al, B, F, and an alkali metal as its chemical composition. Relative to the total content of the above chemical composition, the total content of Si and B is 50.0 mol% to 80.0 mol%, the Al content is 0.1 mol% to 10.0 mol%, the F content is 0.1 mol% to 10.0 mol%, and the alkali metal content is 15.0 mol% to 25.0 mol%.
