diamond tool according to which of several varieties classified material

CVD diamond is a diamond material of high wear resistance of pure, non-binding agent, which is at low pressure (<0.1MPa) prepared under. CVD diamond films are coated CVD (CD) and CVD thick (TFD) forms.CD is a CVD (chemical vapor deposition) process, the carbide substrate (K type alloy used) is General purpose blade  deposited to a thickness of about 10 ~ 30μm, composed of a polycrystalline diamond film is made.Matrix is ​​made easy due to complex shapes, it applies to the complex geometry of the tool, such as taps, drills, end mills and band chipbreakers indexable inserts and so on. International instruments the market have a CD tool products, such as the diamond blade saws  Swedish Sandvik's CD1810 and the United States Kennametal's KCD25, mainly for non-ferrous metals and non-metallic materials, high-speed precision machining, tool life than uncoated carbide tools increased nearly tenfold or even several times. Diamond saw blade, but not suitable for processing of metal cutting tools CD a class of composite materials, composite materials because of hard particles in a very short period of time a coating on the surface of the tool will be worn out, so even though prices than similar tools CD PCD tools to be low, but the diamond film and the adhesion between the base material is small, so limiting its wide application.
