Deep analysis of the current situation and development trend of domestic diamond tools
As a superhard material with excellent performance, the use of synthetic diamond is inestimable. From the point of view of synthesis method, it has experienced high temperature and high pressure method, detonation method and chemical vapor deposition method. The basic principle is to provide a similar environment of high temperature and high pressure in the crust to achieve the purpose of synthesis. From the material morphology and quality point of view, diamond needs to experience low-quality micro-powder, to the high quality, perfect structure of nano-size and gem-level size, single crystal and polycrystalline common development, and finally a variety of doping to meet the functional requirements, simple to micro and macro two-way development, and finally achieve functional. From the application point of view, diamond needs to be from the traditional

Jiangxi Poyang | diamond "legion" stone in the gold, to create a tool town!
"King Kong soldiers" dig gold in the stone to extract Poyang, many people may think of Poyang Lake, Poyang County is on the east bank of Poyang Lake. Practitioners in the stone industry must know about Poyang, but there are few diamond practitioners in Poyang who do not know. Yangyuan Village, Tianfan Street Town, which has the title of "China's First Diamond Village", has grown rapidly like a snowball in recent years by virtue of its relatives and neighbors. Recently, 365 China Stone Network www.stone365.com Xiaobian came to Poyang Industrial Park Tianfan Street Industrial Base, and what came into view was a clean, tidy and standardized factory for diamond enterprises.

Research Progress of Diamond Brazing Technology
Diamond abrasive particles have excellent properties such as high hardness, strong wear resistance and excellent thermal conductivity, and are widely used in the processing of hard, brittle and difficult-to-process materials such as cemented carbide, ceramics, glass, and gemstones. However, there is a high interface energy between the diamond with covalent bond structure and the general metal, which is difficult to weld, and the general mechanical mosaic and physical adsorption do not have enough holding force [1]. Since the early 1990 s, foreign countries and Taiwan have successively studied the use of high-temperature brazing process to develop a new generation of diamond tools, using active metal elements (such as Ti, Cr, Mo, W, etc.) at the interface between metal brazing filler metals and superhard abrasive grains.
