Notes:
In this paper, we emphasize that residual stresses in a ground surface are primarilygenerated due to grinding zone temperature effect, and discuss grinding zone temperature can bedebased based on characteristics of the thin vitrified bond CBN wheel and quick-point grinding. Viaexperimental results of 5 group working procedures, we find that surface roughness Ra showed atendency to reduce slightly with infeed rate reduced, cut depth increased, grinding wheel speed andgrinding variable angle increased, the favorable residual compressive stress could obtained alongwith variables angle(α, β) increased, the sub-surface white etching layer and tempered martensitelayer in size become thinner with α, β angle and grinding wheel speed increased when removal rateZ=0.06mm3/mm keep constant in quick-point grinding, by contraries, surface quality weredecreased entirely when variables angle(α, β) equal to zero. The results indicate it is important thatgrinding variable angle were choice in quick-point grinding for to obtain favorable residualcompressive stress
