Application of Super Abrasive Raw Material – Diamond & CBN
Application of Super-hard Abrasive Raw Material – Diamond & CBN Super-Abrasive Materials: Diamond and CBN The hardest and the second hardest materials on earth. Approximately 90% of diamond used in varies industry are manufactured synthetically.
Features of Synthetic Diamond Synthetic diamonds are also called Laboratory diamonds or cultivated diamonds in the industry. It is a mineral composed of pure carbon and the hardest substance in nature. It has high hardness and good wear resistance, and can be widely used in cutting, grinding, and drilling. Due to its high thermal conductivity and good electrical insulation, it can be used as a heat sink for semiconductor devices; it has excellent light transmittance and corrosion resistance, also widely used in the electronics industry.
By using static ultra-high pressure (50 ~ 100kb, 5 ~ 10GPa) and high temperature (1100 ~ 3000 ° C) technology, through the reaction of carbonaceous materials, such as graphite and certain metals (alloys) to generate diamond, its typical crystal state is cubic (hexahedral), octahedron and hexa-octahedron and their transition forms. Applications: 1. Manufacture of resin-bonded abrasives or grinding tools, etc. 2. Manufacture of metal-bonded abrasive tools, ceramic-bonded abrasive tools or grinding tools, etc. 3. Manufacture of general geological drilling bits, semiconductor and non-metallic materials cutting tools etc. 4. Manufacture of hard formation geological drill bits, correction tools and non-metallic hard and brittle materials processing tools, etc.
Boreas Diamond Micron Powder refers to diamond particles with a particle size smaller than 36/54 microns, including single crystal (monocrystalline) diamond powder and polycrystalline diamond powder. The material is produced by a special process method., and used in precision grinding, grinding, polishing and superfinishing to achieve high-precision machined surfaces.
Diamond micron powder has high hardness and good wear resistance, and can be widely used in cutting, grinding, drilling, polishing, etc. It is an ideal raw material for grinding and polishing hard alloys, ceramics, gemstones, optical glass, and other high hardness materials. Diamond micron powder products are tools and components made from diamond micron powder. Application: Diamond micron powder is the hardest ultra-fine abrasive. It has been widely used in machinery, aerospace, optical instruments, glass, ceramics, electronics, petroleum, geology, and military industries. It is used for grinding and polishing cemented carbide ceramics, gemstones, optical glass, etc. Ideal material for hard materials. Generally, 0-0.5-to-6–12-micron diamond powder for polishing. 10-15 micron to 22-36 micron for grinding. 12-22 micron for fine grinding.
Features of Cubic Boron Nitride (CBN) Cubic Born Nitride (CBN) with a microhardness of HV7200-9800, which is lower than diamond. Boron nitride forms similar in structure to diamond, also known as cubic boron nitride, c-BN, β-BN, or z-BN, Applications: CBN are widely used in cutting hardened steel, gray cast iron, titanium alloy and superalloy because of its high hardness and other good properties such as wear resistance thermal conductivity, high temperature stability and chemical stability. It is suitable for binder systems such as resin, metal, ceramics, etc. It can also be used to produce polycrystalline composite sintered body and can also be used as abrasive particles and abrasive paste. Boreas CBN Series: CBN-B1: black mono-crystal, irregular shape, medium strength, high thermal stability, protruding acute angle, high performance and grinding efficiency CBN-B5: series are Dark brown in color, monocrystalline with irregular shape and angular particle shape, high strength, and high thermal stability CBN-G: series are Golden color monocrystalline, with regular shape and good transparency. This series has the highest strength and thermal stability among all our CBN products. CBN-AM: series are amber color Cubic Boron Nitride micron powder, with high purity, high wear resistance, high thermal stability, good self-sharp ability, and high grinding efficiency CBN-BM: series are black cubic boron nitride micron powder, with high purity, good thermal stability, good self-sharp ability, and high grinding efficiency.
