In order to examine the machinability of high manganese steel castings, turning and facing tests with carbide and ceramic tools were performed, and tool wear, cutting resistance and surface roughness were observed ; and then, hot machining by electric current was studied with M10 carbide tool. The main results are as follows : 1) The best of used tools is M10 carbide tool for cutting the high manganese steel castings, and the optimum cutting speed is 40～60m/min. 2) The machinability of the high mangase steel castings : the growth of flank wear is larger than that of groove wear and the tool life is short : the cutting resistance decreases monotonously with cutting speed ; the surface roughness is comparatively fine. 3) The tool wear increases with electric current in hot machining of the high manganese steel castings ; i.e., this method is inadequate to the improvement of the machinability.
