Development of New Type Vacuum Brazing Diamond Tools

In recent years, with the demand of high speed grinding, ultrahigh speed grinding and precision grinding increasing, as well as the strengthening of environmental protection consciousness, people have done a lot of research and development that is fruitful on the brazing technology of single crystal diamond.

The key to realize single crystal diamond brazing is the strong carbide forming elements contained in the solder. Strong carbide forming elements are active elements, and the heat resistance of single crystal diamond in atmospheric environment is limited, so the realization of single crystal diamond brazing are in a vacuum (10-4 ~ 10-3 pa) conditions.

Single crystal diamond brazing process can help to realize the metallurgical combination of brazing filler metals and metal matrix, and it has high holding strength. The bare height of diamond can reach 50%~80%, so this kind of diamond tools have high cutting efficiency, good sharpness, high use efficiency and many other advantages. And the subsequent processing of single crystal brazing diamond tools is simple, especially without a lot of work of conventional diamond tools, and also without the environment pollution of electroplating tools. For the manufacturers, it can help reduce the cost, and for the consumers, it can help use better tools at the same price, but also a great contribution to the environment protection.

The advantages of diamond on the vacuum brazing and the development and market development of several kinds of new type vacuum brazing diamond tools (vacuum brazing metal cutting piece, vacuum brazing ceramic tile drill, etc.), make the application of vacuum brazing technology more extensive, which not only opens up everybody's view, but also more greatly promotes the research, progress and industrialization of vacuum brazing technology in our country at the same time. As a new type of green energy conservation and environmental protection, low cost manufacturing technology, it will certainly replace some high pollution, high energy consumption industries, but also will bring great social benefits and economic benefits.
