Experiment with SPS (discharge plasma sintering method) successfully prepared nano tungsten carbide wc-7Co, using the intercept method WC grain size were tested, the results showed that the average particle size of nano-products of tungsten carbide WC-7Co at about 200 nm. When using nano-carbide WC-7Co making nano tungsten carbide cutting tools, tungsten carbide nano first round sintered WC-7Co rough cut with a knife Cutting block, then Japan and around the flank of the blade were used W40 , W10, W3.5, W1 diamond grinding coarse grinding, fine grinding, ultra-fine grinding and non-feed grinding on ELID (Electrolytic In-process Dressing, ELID) ultra-precision surface grinder, finally succeeded to obtain nano tungsten carbide WC-7Co knife block.
