Product development background of diamond tools

Tools are an extension of human ability and a lever to promote social development and progress. Tools play an irreplaceable role in the history of human development. With the requirements of high efficiency and high precision, the production technology of tools is increasingly demanding. Fifty years ago, people have been trying to find out how to change the hard and inefficient working conditions in the hard and brittle material processing industry. Until 1955, the United States successfully synthesized synthetic diamonds for the first time, which laid the foundation for the manufacture and popularization of diamond tools, and also brought dawn to many difficult hard and brittle non-metallic materials processing industries, becoming an epoch-making tool revolution in human history, and the processing efficiency was significantly higher than before. With its incomparable performance advantages, diamond tools have become the only effective tools for processing hard and brittle nonmetallic materials. For example, only diamond tools can process superhard ceramics, and there are no other substitutes. Diamond grinding wheel is used to grind cemented carbide, which is ten thousand times more durable than silicon carbide. Using diamond abrasive instead of silicon carbide abrasive to process optical glass can improve production efficiency by several times to dozens of times. The service life of diamond polycrystalline drawing die is 250 times longer than that of cemented carbide drawing die.

With the continuous development of China's economy, diamond tools are not only widely used in modern high-tech fields such as civil construction and civil engineering, stone processing industry, automobile industry, transportation industry, geological exploration and national defense industry, but also appear in many new fields such as gems, medical instruments, wood, glass fiber reinforced plastics, stone crafts, ceramics and composite non-metallic hard and brittle materials, and the social demand for diamond tools has increased greatly year by year.

As far as product positioning is concerned, the diamond tool market is generally divided into professional market and ordinary market. The demand for diamond tools in the professional market is mainly reflected in the high performance index, that is, for specific cutting equipment and specific cutting materials, diamond tools must meet certain technical indexes such as cutting efficiency, cutting life and machining accuracy. The output of professional diamond tools only accounts for about 10% of the whole diamond tool product, but its market sales account for 80% ~ 90% of the whole diamond tool market.

In 1960s, diamond tool manufacturing industry took the lead in realizing industrialization in developed countries in Europe and America, and developed rapidly. In 1970s, Japan won a competitive advantage with its relatively low manufacturing cost, and quickly became one of the leaders in diamond tool manufacturing. In 1980s, South Korea replaced Japan as a rising star in the diamond tool industry. In 1990s, with the global rise of China's manufacturing industry, China's diamond tool manufacturing industry also started, and gradually showed strong competitiveness. After more than ten years' development, there are thousands of diamond tool manufacturers in China, with an annual output value of over10 billion yuan, making it one of the main suppliers in the international diamond tool market after South Korea.

With the technical accumulation and progress of China in the diamond tool manufacturing industry, China diamond tool enterprises are now fully capable of manufacturing medium and high-grade diamond tools, and the product cost performance advantage is remarkable. The technological monopoly of western countries in the middle and high-end professional market has been broken. The trend of China diamond tool enterprises entering the middle and high-end market has already appeared.

As far as product types are concerned, China diamond tool enterprises mainly produce diamond saw blades, diamond drills, diamond bowl milling cutters, diamond cutters, diamonds, diamond resin grinding blocks and other products. Among them, diamond saw blade is the most variety among diamond tool enterprises in China. 1. According to the binder, there are three categories: resin, metal and ceramic bonded diamond tools. Metal bonding process can be divided into sintering, electroplating and brazing.

2, according to the use of structure division

There are: abrasive tools-grinding wheels, rollers, rollers, edging wheels, grinding discs, bowl mills, soft grinding discs, etc.

Sawing tools-circular saw blade, row saw, rope saw, bucket saw, band saw, chain saw and wire saw;

Drilling tools-geological and metallurgical bits, oil (gas) well bits, engineering thin-wall bits, stone bits, glass bits, etc.

Other tools-dressing tools, cutters, wire drawing dies, etc.

Compared with metal bond, resin and ceramic bond have lower strength and are not suitable for sawing, drilling and dressing tools. Generally, only abrasive products are available. According to their differences, they are mainly divided into diamond abrasives, diamond saw tools, diamond tools and diamond drilling tools.
