After the edm surface is much more difficult than ordinary mechanical processing or the surface of the heat treatment after grinding, so fine gauge should be used before the end of edm edm dressing, otherwise will form the surface hardening thin layer. If improper selection edm refinement gauge the depth of the heat affected layers of up to 0.4 mm. Hardening of the thin layer of hardness is higher than matrix hardness, must be removed.
