Superabrasives materials and their products and tools have been widely used in the industry. They not only solve the problems that cannot be processed or difficult to process with traditional tools, but also significantly improve the efficiency of traditional processing, and significantly reduce consumption and waste emissions.
Several superabrasives material products and tools
(a. blade; b. grinding wheel; c. saw blade; d. drill)
1) Natural diamonds
Diamonds obtained from natural diamonds are called natural diamonds. Natural diamonds are brilliant, gorgeous, rare and precious, and are regarded as treasures by people. There is an advertising slogan "Diamonds are forever, and a diamond is forever spread" among women and children in our country.
In addition to being used as jewelry, natural diamonds are used more in industrial applications. The industrial use of diamond has long been the use of its particularly high hardness. The diamond knife for cutting glass reminds us: the use of diamond to prepare drill bits for geological exploration and oil and coal mining. Diamond will react with oxygen to different degrees at high temperature, especially it has a good affinity with iron and is not suitable for ferrous metal processing.
2) man-made diamonds
Man-made diamonds are often called laboratory synthetic diamonds or cultivated diamonds in the industry. Synthetic diamonds with large particles or large single crystals have been used to process synthetic diamond jewelry
Man-made diamonds are also genuine diamonds, with the same composition and structure as natural diamonds. The two can only be distinguished in a very special way. For example, under a cathodoluminescence instrument, the growth texture of the former is geometric, while the latter is ring-shaped. Beginning in 2006, jewelry institutions such as GIA began to provide identification services and issue certificates, mainly to prevent merchants from selling low-priced synthetic diamonds as natural diamonds.
In the past, researchers in the diamond industry have been looking for ways to efficiently synthesize artificial diamonds, but there has been no breakthrough. The two main obstacles are cost and production factors. After decades of research, the technology for synthesizing large diamond single crystals by ultra-high pressure and high temperature under static catalyst conditions is now mature.
my country has achieved rapid development in the development and application of synthetic diamond large single crystals synthesized by ultra-high pressure and high temperature method, as well as the technology development and application of synthetic diamonds synthesized by microwave plasma CVD method. Synthetic diamond jewelry has been sold in the market and has begun to take shape Market size
1) Used as abrasive material.
It can be used not only for the processing of iron-based materials, but also for the processing of non-ferrous metal materials.
2) Used as tool material
Generally, polycrystalline cubic boron nitride is used for cutting tools. PCBN is a micropowder prepared from CBN single crystal by adding adhesives such as titanium carbide and cobalt, and then sintered at high pressure and high temperature using a six-sided top press. It is particularly effective for the processing of iron group metals and their alloys, especially suitable for high-speed cutting and dry cutting, and realizes the use of turning instead of grinding and milling instead of grinding, which greatly improves production efficiency
3) Used as a functional material
High thermal conductivity CBN can be applied to optoelectronic functional devices.
Superabrasives material is a small variety among many different materials, but it is an irreplaceable material and may gradually replace some other materials.
