Based on the surface grind hardening experiment, major forms of two side-direction burr are given out through the experimental observation, as well as its formation and variations are studied. The studies show that in the processes of the grinding-hardening, metal in the vicinity to the contact region under the high temperature plastic flows toward the free surface without constraints in two sides so to form the two side-direction burr, under the action of an abrasive wheel. The morphology and size of two side-direction burr varies with changes of the grinding conditions. The higher the grinding temperature is, then the larger the grinding force is, and the bigger the size of the two side-direction burr is.
