Tungsten carbide cutting tool wear is inevitable in metal machining, the tool along the front surface of the chip load and high speed tool flank slip and friction generated energy is converted to heat, and this heat is taken away chips usually remaining among the incoming heat tool, heat and temperature are fundamental tool wear. Tungsten carbide cutting tool wear mechanism into abrasive wear, the phase transition wear, adhesive wear, diffusion and oxidation wear five forms. Reasonable choice of tool material, tool geometry parameters can improve the wear resistance, heat resistance and chemical stability of the tool. In addition, to improve the strength and tool sharpening tool quality, improve heat dissipation, the rational use of cutting fluids, can effectively prevent tungsten carbide tool wear.
