Description
Introduction:
CVD (Chemical Vapor Deposition) diamond is a mixture of carbon-containing gas and hydrogen at high temperatures and sub-standard atmospheric pressure is excited to decompose to form an active diamond carbon atoms and deposited on the substrate intergrowth of polycrystalline diamond. Since CVD diamond does not contain any metal catalyst, so its thermal stability close to natural diamond. CVD diamond grains are disordered, non-brittle cleavage plane, thus showing isotropic. CVD diamond is widely used in mechanical, microelectronics, thermal, optical, aerospace, military, medical and other fields.our company mainly produces the following types of CVD diamond products: CVD diamond wire drawing die core, CVD diamond dresser blank, CVD diamond cutter blank, thermal grade CVD diamond blank, optical grade CVD diamond blank and other multi-grade CVD products. and can be cut according to user requirements, polishing and other processing.
Product introduction:
CVD Blanks for Dressing produced by our company does not contain any additives, is pure diamond with polycrystalline structure, there is no soft and hard surface of the points, and is not easy to break, with high hardness, wear resistance and thermal stability characteristics, different grades of billet wear ratio between 20 to 1.8 million, stable performance, dressing out of the wheel, high processing smooth finish, I produced the CVD Diamond finishing tool blank can be used to make single-point Diamond pen, multi-point grinding wheel dresser, trimming wheel, forming knife, etc., is the ideal substitute for natural diamond and single-crystal diamond.
