The basic mechanism for the more hardened ground surface/subsurface is most likely due to the size effect induced by severe strain gradient in grinding. The smaller down feed in grinding induces a severe strain gradient in near surface, while the relatively larger depth of cut in turning may substantially reduce the size effect.

Be sure that any new grinding wheel is sized correctly. As the size of the wheel radius increases, the rim speed increases, despite the face that the motor rpm is the same. If using an oversized wheel, there is a risk that the speed at the rim (peripheral speed) and any centrifugal force becomes so great, that the wheel comes apart.
