What are the diamond tools included?
In recent years, with the use of diamond tools more and more widely, its development is more rapid, today we recall what are the existence of diamond tools around it! Diamond tools are products with a certain shape, performance and use made of diamond grain size sand and micropowder as cutting materials, with the aid of binder or other auxiliary materials. Diamond tools by purpose include:(1) abrasive including fixed abrasives, coated abrasives and loose abrasives, such as grinding wheels, sand tiles, grindstones, grinding heads, abrasive belts, abrasive pastes, etc. (2) sawing tools are divided into two categories: one is the circular data for sawing granite, marble and concrete,

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

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.

Improving the quality of diamond tools in China should start from the process.
The survey results show that China's total stone output, stone export volume and stone consumption have reached the first place in the world: there are more than 20000 stone processing enterprises with nearly 5 million employees, with an annual output of 6 million cubic meters of stone and 0.12 billion square meters of plates. the annual output value exceeds 80 billion yuan, has more than 500 advanced production lines, and the total import and export volume exceeds 1.2 billion US dollars, making it a veritable stone producer. China is also a large ceramic producer. In 1999, the total output of all kinds of ceramic tiles was 1.6 billion square meters (33.6 per cent of the world's total output) and the total consumption was 1.3 billion square meters (the world's total consumption
