Hard turning versus grinding—the effect of process

Compared with grinding, hard turning may induce a relatively deep compressive residual stress while still achieving an equivalent surface finish. Although it is generally agreed that deep compressive residual stresses are beneficial to component life in rolling contact, the interactions between the residual stress profile, applied load, and surface material are poorly understood at present.
