Notes:
Nano-cemented carbide is a novel material, which is superior to common cementedcarbide on physical and mechanical properties, such as high hardness, toughness, flexural strengthand higher wear resisting property. It is proposed to have wide application prospect to tools andmould manufacturing.In this paper, ELID grinding technique is applied to grind nano-cemented carbide tools. And theground surface quality, cutting edge radius, and machinability of nano-cemented carbide tools arestudied, compared with common cemented carbide. It is demonstrated by experimental results thatnano-cemented carbide has higher grinding surface quality with less surface flaw than that ofcommon cemented carbide. The cutting edge radius of nano-cemented carbide tool is less than thatof common cemented carbide tool. Under the same conditions, the tool life of nano-cementedcarbide is 1~2 times longer than that of common cemented carbide. The research results indicatethat ELID grinding technique is suitable for grinding cemented carbide tools. Nano-cementedcarbide tools have better machinability than common cemented carbide tools
