A problem in the manufacturing of precision bearing rings is reduced outer diameter (OD) cylindricity when grinding inner diameter (ID). Shot blasting is used to remove surface scale from hardened rings prior to grinding. The basic hypothesis is that ID grinding releases residual surface stresses from blasting resulting in reduced OD cylindricity.
