Surface Hardening: Hard Turning or Grinding? | Gear ...
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.

Grinding is the act of balancing on a Grind Rail and then moving down such rails at high speeds. Most practitioners grind with their feet on the Grind Rails while others grind using other parts of their bodies, like their rear. Extreme Gear practitioners on the other hand always grind with their Extreme Gears on the Grind Rails.
