Natural stone (granite, marble), jade, high-grade artificial stone (microceramics, glass, and cement products, etc.) have been widely used in the decoration of houses and buildings, used in the production of various decorations, and used in daily necessities and In the construction of roads and bridges, the processing of these materials requires a variety of diamond tools. In the past decade or so, Chinese companies producing diamond tools have also developed rapidly.
Natural stone (granite, marble), jade, high-grade artificial stone (microceramics, glass, and cement products, etc.) have been widely used in the decoration of houses and buildings, used in the production of various decorations, and used in daily necessities and In the construction of roads and bridges, all kinds of diamond tools are needed to process these materials.
According to their different uses, diamond tools are mainly divided into several categories: diamond grinding tools, diamond sawing tools, diamond cutting tools, and diamond drilling tools. Diamond is hard, so the diamond tools made are particularly suitable for processing hard and brittle materials, especially non-metallic materials.Such as stone, wall and floor tiles, glass, ceramics, concrete, refractory materials, magnetic materials, semiconductors, gems, etc.; it can also be used to process non-ferrous metals, alloys, wood, such as copper, aluminum, hard alloys, hardened steel, cast iron, and composites Wear-resistant wood boards, etc. At present, diamond tools have been widely used in industries such as construction, building materials, petroleum, geology, metallurgy, machinery, electronics, ceramics, wood, and automobiles.
Diamond tools have been widely used in industries such as construction, building materials, petroleum, geology, metallurgy, machinery, electronics, ceramics, wood, and automobiles. Diamond tools are an emerging industry, and there is still a lot of room for the replacement of traditional tools. At present, China and South Korea have become the world's diamond tools production bases, and developed countries in Europe and the United States still retain a small amount of high-end production capacity.
Taking the United States as an example, my country's diamond tools account for about 45% of its imports, including South Korea about 75%. As the entry barrier for diamond tools is not high, the domestic concentration is very low. There will be a large number of small tool processing companies in the stone production base, which often only produce a few types of products. Compared with large-scale enterprises, there is a big gap in profitability. With the upgrading of diamond tool categories and the return of gross profit margins, the industry There is a trend of integration.
Research and analysis of the development and application of diamond tools show that the application of coated diamond tools is of great significance to the development of diamond tools. Application and progress of coated diamond tools. Diamond plating is to coat a layer of affinity metal (Ti, Cr, W, Mo, etc.) on the surface of diamond tools. The advantage lies in the formation of chemical bonds between the plating layer and diamond, and the surrounding The matrix of the diamond is formed by brazing combination to improve the holding force of the diamond tools matrix and the diamond.
In addition, diamond tools are plated with different metals, and then analyzed by X-ray diffraction studies. It is shown that a variety of different carbides are formed on the diamond surface, resulting in new chemical bonds, such as TiC, Cr3C2, Cr7C3, WC, W2C, MoC, Mo2C, etc., improve the holding power of diamond tools, the diamond particles and the matrix metal form a "chemical/metallurgical bond", increase the bonding strength between the diamond tools and the matrix, and can resist the oxidation and graphitization of the diamond, and improve the diamond tools’s performance The service life improves the performance of diamond tools!
