Abstract: Aiming at the grinding fluids influence on grinding forces and grinding temperature field in the grinding hardening process, a simulation model of non-quenched and tempered 45 steel was established to analyze the influence of different grinding fluid parameters on the grinding workpiece surface hardness and residual stress. At last, the workpiece surface hardness and its surface integrity after plane grinding hardening experiment by changing the grinding fluid parameters were studied. The results showed that the surface microstructure damage has a closest connection to the grinding depth. Adding a certain amount of grinding fluid can effectively reduce the surface microstructure damage, but it seriously weakens the effect of using grinding heat to strengthen the workpiece surface.

Key words: grinding hardening, grinding fluid, surface residual stress, hardness, microstructure damage
