Polycrystalline diamond

In synthetic diamond single particle basis by a special process of production from the current sintering cubic boron nitride in accordance with polycrystalline diamond can be roughly divided into three types, namely, sintered, growth pattern and growth - sintered. The main product is sintered type (S-type), which is a polycrystalline diamond powder as raw material, with or without additives and with additivesabrasive grinding and pressure conditions, so that a block of sintered synthetic diamond, and its structure and cappuccino that is more similar to grain disordered, no direction, no cleavage plane. This is the most significant features of the diamond one, so in the course of a micro blade broken, and will not occur in brittle fracture under shock loading, chipping caused by non-cutting wear and tear damage. In this way, the service life can be significantly extended.
