Structure and Characteristics of Diamond Bit

In machining, diamond grinding wheel, PCD tools and tools, honing oil stone, finishing roller and drawing die are widely used.The performance of the polycrystalline diamond drawing die is better than that of natural diamond die and hard alloy die. Therefore, many applications are made in the wire drawing industry, especially the appearance of CVD diamond drawing die, which provides reliable wire drawing tools for controlling wire materials under 15mm.PCD cutting tools are mainly used in the processing of non-ferrous and non-metallic materials. It is reported that the demand for PCD cutting tools is increasing year by year in automobile, motorcycle, household appliances, wood processing and general machinery industries.Although various diamond tools produced in China have been widely used in various industries and achieved remarkable economic benefits, there is still a certain gap between their technological level and that of foreign similar products, which is mainly reflected in:

1. The whole diamond tool industry lacks unified management and macro-control.Due to blind development, the whole production layout of diamond tools appears scattered, disorderly and blossoming everywhere. The quality of products in the tool market is unstable, the competition is disorderly and the price is chaotic.

2, because of the diamond single crystal production and the development of diamond tools are not harmonious, make the development of diamond tools in China lags behind the growth of diamond single crystal production, cause the backlog of diamond and slow-moving, influence and restrict the sustainable development of the diamond industry in China, serious landslide diamond production enterprise economic benefits.

3. The application field of diamond tools is narrow, the product variety is single, the quality is not stable, and some product technical quality standards are confusing, and there is no unified management standard and standard for product quality inspection and supervision.

4. The production equipment and overall technical level of diamond tools are relatively backward, and some advanced new technologies and new technologies are slow to be promoted and applied.

5. The scale of production enterprises is generally small, the production is not concentrated, the technology is poor, the market competitiveness is lacking, and the economic efficiency is not high.

6. Insufficient investment in diamond tools production, new product development and technological research.

7. During the use of diamond tools, the use rate of matrix materials is low and the steel waste is serious.In the process of use, there are many diamonds that are not normally worn, shed and left, which makes the actual utilization rate of diamond is low and the waste of diamond materials is large.
