Diamond circular saw blade is one of common cutting tools and nowadays it is widely used for cutting some hard and crisp materials such as stone materials, ceramics and others. When looking at diamond saw blade, you would notice that it is constituted with two important parts including saw blade tool bit and its matrix. Matrix is the main supporting part which plays the role of cohere tool bit, as for the tool bit, it plays the role of cutting during working process. Because of their different function and different materials, tool bit would be worn down gradually during the using process, however, it is not the condition for matrix. Do you know why tool bit could play the role of cutting? In fact, diamond, including natural diamond or sometimes artificial diamond, is contained inside, as is known to all, up to now, diamond is the hardest material in the world, when cutting materials, diamond will rub the cutting material, this is its working principle. By the way, diamond particles are contained inside of tool bit.

In current years, there are still some problems which should be solved in the future in diamond Industrial production, for example, the technology of large area and high speed diamond heavy layer deposition, how to control the diamond membrane’s crystal boundary density and defect density, how the diamond membrane could be grown in low temperature, and why the binding force between diamond thin film and matrix is so weak. Because of the better cutting performance of diamond cutting tool and the promising development in the future, nowadays experts in both at domestic and overseas have put more and more research on diamond using, and the good news is that there are already some great improvement, and it is believed that in the future diamond cutting tools including diamond circular saw blade will be widely used in modern processing industry.

When talking about the manufacture workmanship of diamond saw blade, in general, there are mainly three workmanships, and in fact, based on different manufacture workmanships, diamond saw blade can be divided into three types.

Firstly, sintering diamond saw blade, it can be divided into cold pressing sintering technology and hot pressing sintering technology.

Secondly, electroplate diamond saw blade, with electroplate technology, tool bit powder is adhered to the saw blade matrix.

Thirdly, welding diamond saw blade, it can be divided into high frequency welding diamond saw blade and laser welding diamond saw blade.
