CUBIC BORON NITRIDE ABRASIVE BODIES |
摘要 |
A tool insert comprises an abrasive compact comprising a polycrystalline mass of cubic boron nitride particles present in an amount of at least 70 percent by volume and containing substantial direct particle-to-particle bonding and a second phase dispersed through the cubic boron nitride particle mass. The abrasive compact presents major surfaces on each of opposite sides thereof. The one major surface provides a cutting point for the insert and the other major surface has bonded thereto a layer of molybdenum of thickness less than 0,5 mm. The largest linear dimension of the compact is no more than 10 mm. The tool insert is designed for applications where a high removal rate of work piece is desired. |
