Abstract
It is increasing in the importance of the highly efficient processing of high speed or high feed rate cutting as the means of the cost reduction and the environmental protection. Ti(C, N) based cermet indicates high wear resistance as low reactivity with steel. High efficiency cutting of Ti(C, N) based cermet is important to improved plastic deformation at high temperature. It's indicated microstructure of Ti(C, N) based cermet depend on grain size of powder, plastic deformation resistance of Ti(C, N) based cermet increasing with increase amount of WC in a series of studies. Super fine cermet GT/NS700 series is developed based this research for long tool life and stable high speeds cutting.
