In recent years, domestic investment in diamond tools is far inferior to diamonds, and the difference in currency investment is more than an order of magnitude. However, diamond tools are still developing at a faster rate than diamonds in recent years. A number of enterprises with new models, good benefits, and higher technological content have spontaneously emerged. Some of these enterprises have already impressed foreign counterparts and developed tools for diamonds. Putting forward higher and higher requirements has promoted the development of diamond; in order to change the passive situation of the diamond market, the development of tools is one of the ways to solve the difficulties of diamond enterprises.

Diamond tools are divided into three categories: metal, ceramic and resin according to the type of binder.

Metal bond diamond tools are mainly produced by electroplating and powder metallurgy. The powder metallurgy method is also called the cermet method, such as hot pressing sintering, cold pressing sintering, pressureless sintering, pressureless impregnation, vacuum or atmosphere protection sintering, immersion and so on.

Hot pressing sintering is divided into electric hot pressing (including resistance hot pressing, electric spark hot pressing), intermediate frequency hot pressing, and hot isostatic pressing.

The main disciplines and categories of metal bond diamond tools are: metal science, powder metallurgy, hydraulic power, physics, chemistry, thermodynamics, dynamics and so on. Diamond has single crystal, polycrystalline sintered body, and polycrystalline film. In the polycrystalline sintered body and tool binder, it involves doping and interface bonding theory, diffusion theory, alloying theory, phase transformation and dislocation theory...

There is a problem with diamond tools, which cannot be figured out without advanced analysis and testing methods.

The main related factors that affect the quality of metal bond diamond tools are: 1.diamond;

2. raw metal powder;

3. tool manufacturing technology;

4. quantification and tool quality;

5. inherent deficiencies in the production method;

6. equipment, spare parts, raw materials and personnel quality, etc.
