Pressure sintering using conventional methods is difficult to achieve

Instruments of diamond powder, diamond powder products are mainly stage sintering furnace by sintering compacts, sintered diamond tools and general process, the sintering temperature is influenced by changes in  Diamond blade graphitization temperature limit, the binder of the diamond easily not strong bonding between the diamond or cause burning, and for shaped diamond powder products (such as sawtooth workpiece, the workpiece surface, etc.), the use of conventional pressure sintering method is difficult to achieve, the current general shaped workpieces by means of  synthetic diamond powder obtained benefit from this method, using a laser to make powder compacts fast heating and subsequently cooling rapidly the characteristics of the entire sintering process time can be greatly reduced at higher  synthetic diamond to avoid excessive burning of diamond, diamond tools combined conventional sintering techniques proposed new diamond powder tool manufacturing method --- diamond powder compacts laser sintering, can reduce diamond burning, improve the sintered body of the diamond substrate holding force, but also for shaped sintered .
