Determine the performance of the cutting tool substrate three elements of

Determine the performance of cutting tools three elements of matrix material and geometry geometry tool coating. Because of this, although China as carbide mineral resources in the country, but in the finished tool, due to domestic and coating  polycrystalline diamond  and groove design the technology gap, though it is the same material billet rods and knives, made of rigid alloy in the performance of the tool has been subject to large foreign  synthetic diamond . At present, the material properties of cubic  abrasive grinding  and cubic boron nitride inserts the preparation, which was used without any coating and complex geometries, performance is completely determined by the properties of the matrix, which itself determines the physical properties with unsurpassed advantage!
