PCD Cutter Blank:PCD cutting tool blank are produced by sintering selected diamond particles at high pressure and high temperature, and consist of diamond layer and tungsten carbide substrate. Its hardness and wear resistance is as well as the nature diamond and the toughness as same as carbide alloy.

PCBN Cutter Blank:The utility model relates to a polycrystalline cubic boron nitride (PCBN) cutter with improved interface property. The cutter comprises a CBN blank, an Al powder blank and a substrate, wherein the Al powder blank is positioned between the CBN blank and the substrate. The innovation point of the PCBN cutter with the improved interface property is that an Al layer is arranged between the hard alloy substrate and a PCBN layer, so that the interface property of the substrate and a cutter head is high.

Natural Diamond:Natural diamond, also called diamond, which is known as women’s decoration in ancient times. Actually, it refers to some crude material taking its shape through series of chemical reaction, such as in the volcano, where the molecular structure of the carbon element turned into a more stable one under high temperature and high pressure.
In natural diamond, the most common form of diamond crystals is octahedral, while a dodecahedron diamond is rare, cube more rare. In addition, there are many other shapes of convex octahedron, convex dodecahedron, convex hexahedron and their combination. Due to crustal movement, and the impact from the nature, surface crystal is more than the plane ones. On the surface of natural diamond crystal there are some ladder-shaped or uneven reliefs, sometimes appearing with some triangle shaped holes on the octahedral crystal and deep dark lines on the dodecahedron diamond crystal.
The formation and discovery of natural diamond are not easy, because it is a carbon’s transformation under such special conditions in the deep earth as high temperature and pressure after hundreds of millions of years.

Monocrystal Diamond:Single crystal synthetic diamond products are produced by chemical vapour deposition (CVD) or high pressure, high temperature (HPHT) synthesis. The resulting single crystal synthetic diamond is an engineered synthetic material that is highly consistent and has predictable properties and behaviour. Synthetic diamonds (whether formed by HPHT or CVD) have properties such as hardness, thermal conductivity and electron mobility that are superior to natural diamonds. HPHT diamonds offered by iAbrasive.com is considered to be the ultimate synthetic diamond material for synchrotron optics, due to its high thermal conductivity, and to the low levels of crystal structure defects and imprities which can otherwise distort the lattice.

Polycrystalline Diamond:Polycrystalline diamond, PCD or TSP for short. At present, it can be roughly divided into three types according to the sintering mechanism, predominated by sintered compact (S - type), which is a kind of blocky aggregation sintered jointly by lots of fine diamond grains and cemented carbide substrate under high temperature and pressure. Its molecular structure is characterized by grain arranged disorderly, no direction and no cleavage plane, which is one of the most significant features of diamond. Therefore in the using process, it wont cause brittle crack and flaking under impact, and significantly prolong service life.
As a processing tool, PCD is mainly used in oil, metallurgical, geological drill, reamer, etc. Its drilling speed and aging are many times that of natural diamond, and at the same time it also can effectively keep the aperture in the drilling process. Artificial diamond compact can also be used to cut non-ferrous metals and alloys, hard alloy and non-metallic materials, with its cutting speed one hundred times that of the carbide cutting tools and durability thousands of times that of cemented carbide.

Polycrystalline cBN:Polycrystalline CBN, or polycrystalline cubic boron nitride (PCBN), are produced by sintering micron CBN (cubic boron nitride) powders with various binding materials, so as to enhance its hardness and thermal stability. Most PCBN materials are integrally bonded to a cemented carbide substrate. PCBN composites provide extreme resistance to deformation and wear at high temperatures – typically an order of magnitude better than the nearest ceramic materials.
About two thirds of all PCBN tools are used for the machining of hardened steels, offering a viable, more cost effective alternative to conventional grinding processes. Other applications are in the machining of hard, grey and high-strength cast iron, and cold and hot-work tool steels. The machining of nickel and cobalt-based superalloys is a significant and rapidly growing application area for PCBN.

CVD Diamond:CVD is a short form for Chemical Vapor Deposition, which is a chemical process used to produce high-purity, high-performance solid materials. A mixture of carbon and oxygen is stimulated and resolved in such circumstances as high temperature and pressure under standard atmosphere, thus grows into CVD diamond through deposition. Chemical vapour deposited (CVD) synthetic diamond is typically produced in a vacuum system below atmospheric pressure, with the carbon atoms supplied from a gas such as methane. The ability to control gas purity makes CVD diamond growth a particularly effective way to make synthetic diamond for applications requiring very high chemical purity, including optical, electronic and certain mechanical applications.
Because CVD diamond does not contain any metal catalysts, so its thermal stability is very close to that of natural diamond. Similar to synthetic polycrystalline diamond produced under high temperature and pressure, the CVD diamond grains are also arranged disorderly, no brittle cleavage plane, therefore stay isotropic. CVD diamond is now being used as a kind of cutting tools. In addition, lots of chemical vapour deposition (CVD) synthetic diamond products have been used for a wide range of high technology applications including electronics, sensors, lasers and thermal management.
