| Abstract: | On the basis of the research of experiments on cutting tools, the cutting performances of nano.cemented carbide cutting tools and nonnano ones are compared. The results of experiments indicate that nano cemented carbide cutting tools can improve cutting performance, increase breakage resistance and prolong cutting life due to the fine grain size. Nano cemented carbides could be used as cutting tools with excellent cutting performances in automatic production and have comprehensive spreading prospect. |
