Deep analysis of the current situation and development trend of domestic diamond tools

As a superhard material with excellent performance, the use of synthetic diamond is inestimable. From the point of view of synthesis method, it has experienced high temperature and high pressure method, detonation method and chemical vapor deposition method. The basic principle is to provide a similar environment of high temperature and high pressure in the crust to achieve the purpose of synthesis. From the material morphology and quality point of view, diamond needs to experience low-quality micro-powder, to the high quality, perfect structure of nano-size and gem-level size, single crystal and polycrystalline common development, and finally a variety of doping to meet the functional requirements, simple to micro and macro two-way development, and finally achieve functional. From the application point of view, diamond needs from traditional tools (mainly relying on high hardness and high wear resistance) to high-end tools (precision tools), and then to functional devices, in order to play its true value. At present, the application of diamond is also difficult to break away from the scope of tools, as follows.

Diamond tools mainly include abrasive tools, cutting tools, drilling tools, dressing tools, etc., which are widely used in geological exploration, stone, mechanical bearings, semiconductors, sapphires, composite materials, automobiles and national defense industries. At present, China's diamond tools have formed a series of products, specifications are relatively complete, a few products in the international market has a certain degree of competitiveness, most of the product performance and cost performance needs to be improved, low competitiveness.

Analysis of the current situation of global diamond tools

At present, the global diamond market can be divided into three basic types, the first type is Europe and the United States, mainly including the United States and Europe and other countries with advanced technology, they have more than 40 years of experience in diamond tool manufacturing, strong, leading technology, perfect sales system, to a large extent on the market formed a monopoly trend. Some representative diamond tool manufacturing groups in Europe and the United States, such as Husqvarna, have an annual turnover of more than $0.3 billion.

The second type is mainly in Japan and South Korea, its experience in the production of diamonds and tools for more than 30 years, rapid development, in the DIY market and high-end market occupies a certain position, and gradually to the professional market. Among the manufacturers in Japan and South Korea, the related process technologies mainly include hot pressing sintering and laser welding processes. Representative units such as Japan Asahi Diamond Industry Co., Ltd. can produce an annual output value of more than US $0.2 billion.

The third type is China-based manufacturing enterprises, some of China's diamond tools have a high level of quality, some foreign brands of diamond tools are also commissioned by Chinese enterprises. However, most of the products produced by most enterprises are of low quality and low price, although there are many tools, they are low-end products. The quantity and volume of high-quality products together are not enough to compete with foreign countries.

At this stage in the country has been formed in the Beijing area, Shijiazhuang area, Danyang-based Yangtze River Delta region, Fujian Shuitou, Xiamen, Shandong coastal areas, Guangdong Foshan-based Pearl River Delta region and other major diamond tool export base; in addition to Zhengzhou as the center of the Central Plains region and Hubei Ezhou region of diamond tools development is also very fast.

Problems and deficiencies in the development of diamond tools

(1) the independent innovation ability of production enterprises is not strong

The specific situation of the industry is: benchmarking enterprises that pay attention to independent innovation can develop some international high-end products, but the output is not large, it is difficult to meet the needs of domestic and foreign markets. The number of these enterprises is limited and can represent the highest level of the country, but it is difficult to represent the overall level of the industry. Most enterprises have problems of quality and efficiency, rising production and operation costs and insufficient innovation capacity. Some enterprises "to production capacity" task is more onerous, backward production capacity is not large-scale elimination, the development of diamond tool production enterprises is difficult to meet the diversified needs of domestic and foreign markets. At present, many high-end products used in emerging industries need to be vigorously developed to further broaden the application of various products of superhard materials, which is a big test for the R & D ability and innovation ability of enterprises.

(2) Production technology needs to be further improved and specialized.

Most diamond companies because of financial problems can not be completed in a timely manner to update technology, failed to purchase new equipment instruments. If you want to develop first-class products, it is difficult to complete without advanced technology and equipment. The testing of raw materials and the strict control of the production process still need continuous improvement. As we all know, general products have low profits and special products have high profits. If you want to make special products and realize personalized and customized services, you must be familiar with the user's production process and be able to become an application guidance expert. This is not something that a general enterprise or a single team can achieve quickly. Although the degree of product specialization in China has improved in recent years, the task is still very heavy, which is also the only way for the transformation and upgrading of products in the industry.

(3) Improve product quality standards, especially to improve inspection and testing capabilities.

Since 1973, the diamond industry has been conducting standard research and proposing drafts. In 1979, the first industry standard "synthetic diamond" was born, which opened the prelude to the revision of industry product standards. After more than 30 years of development, China's current national and industry standards involving superhard materials and their products have reached 41, which has played a huge role in regulating industry products and promoting industry development. However, with the development of my country's industrialization, the superhard material industry continues to progress, and the application fields of superhard material products continue to expand. There are more and more superhard material product specifications. Many products have no standards to follow. In addition, there are many manufacturers in my country, which directly leads to The specifications of commercially available products are chaotic, and the versatility of products from different manufacturers is poor. In addition, with more and more varieties of diamond products, higher requirements are put forward for our inspection and testing capabilities. Hubei Province has established a national diamond tool quality supervision and inspection center, and gradually fill the gap in the domestic authoritative diamond testing.
