PCD diamond tool

PCD diamond tools ] [ type description:
1 natural diamond Natural Diamond (ND);
2 , synthetic polycrystalline diamond Artificial Polvcrystalline Diamond (PCD);
3 , synthetic polycrystalline diamond compact Polycrystalline Diamond Compact (PDC); chemical vapor deposition of diamond coated tools Chemical
All kinds of diamond PCD tool Vapor Deposition Diamond Coated Tools (CVD).
4 , the deposition thickness of 100μm thick film without a substrate of pure diamond Thick Diamond Film (CD);
5 , the tool directly deposited on the substrate surface of the diamond film thickness of less than 30μm coating Coated Thin Diamond Film (CD).
PCD diamond tool performance characteristics:
Diamond tool with high hardness, high compressive strength, thermal conductivity and good wear resistance and other characteristics , can achieve high machining precision and efficiency in high-speed cutting . The above characteristics of diamond tools are determined by the state of the diamond crystal . In the diamond crystal , the four carbon atoms of valence electrons bond tetrahedral structure , each carbon atom with four adjacent atoms form a covalent bond, and then form a diamond structure , the structure of the binding forces and very strong directivity , so that the diamond has a very high hardness. Since the polycrystalline diamond (PCD) is a structure of varying orientation of the diamond sintered body of fine grain , although the added binding agent , remains below its hardness and wear resistance of the single crystal diamond . However, due to the performance of PCD sintered isotropic , so easy to split along a single cleavage plane .
