| Abstract: | The superfine cermet inserts made from superfine grain TiC 0.7N 0.3 powder were prepared. During machining the hardened and tempered steel 9CrSi, the lifespan of the superfine cermet insert is longer than normal cermet inserts by two to three times, the cutting force is decreased and the quality of machined surface is improved. The mechanism of improving cutting performance of this insert is discussed. |
