Development trend and prospect of synthetic diamond industry

With the maturity of synthetic diamond technology and the rapid development of China's economy, China has accumulated and improved diamond tool manufacturing technology and has strong manufacturing capabilities. Due to the huge advantages of Chinese enterprises in labor costs, coupled with the trend of catching up with technology research and development, Chinese enterprises have obvious advantages in product cost performance. With the rapid growth of market demand, diamond tool companies from all over the world have launched, and a number of advantageous enterprises with international competitive strength have emerged. China has become an important producer, application and exporter of diamond tools in the world, with an annual output value exceeding 10 billion yuan.

How to effectively improve the quality of PCD tools in China

The grade quality, particle size and concentration of diamonds play a decisive role in diamond tools. In China's diamond synthesis, the six-sided top small tonnage high-strength process has matured, the six-face top large tonnage large cavity process has been continuously improved, and the two-sided top synthetic diamond has also begun to take shape. The powder catalyst synthesis, carbon, and pyrophyllite block raw materials are constantly being produced. perfect. Therefore, for the manufacture of diamond tools in China, high-strength diamond with stable performance, coarse particles and good thermal stability is possible. Foreign diamond companies, in addition to launching SDA+, SDB, DSN, MBS, ISD series, DeBeers launched BKI, BK30, BK60, BK70 diamonds for the Chinese market, South Korea's Rijin company launched six-sided synthetic SDS series diamonds, all worthy of China Learn from peers.

Use of cemented carbide tools

Cemented carbide can be used as a variety of cutting tools. The amount of cemented carbide used in cutting tools in China accounts for about one-third of the total cemented carbide production, of which about 78% is used for welding tools and about 22% is used for indexable tools. The hard alloy for CNC tools only accounts for about 20% of the hard alloys for indexable tools. In addition, there are solid carbide drills, solid carbide small garden saw blades, and hard alloy micro drills.
