Grinding With Abrasive Disks: Part 2—Disk Performance and Dressing Mechanisms

Abstract

Performance data for 24-grit aluminum oxide disks on mild steel and on stainless steel are presented. The dressing mechanisms are shown to be different on mild steel and on stainless steel since the whole grit is the cutting tool on mild steel while micropoints are the cutting tools on stainless steel. It is shown that the total weight of metal removed during the life of the disk depends primarily on how long the dressing mechanism continues to function, and that erect grain orientation favors dressing on mild steel but is not a factor in dressing on stainless steel.
