PCDinsert
Diamond tool has the characteristics of high hardness, high compressive strength, good thermal conductivity and wear resistance, which can obtain high machining accuracy and processing efficiency in high-speed cutting. The above characteristics of the diamond tool are ***ermined by the crystal state of the diamond. In diamond crystals, the four valence electrons of carbon atoms are bonded by tetrahedral structure, and each carbon atom forms a covalent bond with four adjacent atoms, thus forming a diamond structure, which has a strong binding force and directivity, so that diamond has extremely high hardness. Because the structure of polycrystalline diamond (PCD) is a fine crystalline diamond sintered body with different orientation, the hardness and wear resistance of PCD are still lower than that of single crystalline diamond although the binder is added. However, because the PCD sintered body is isotropic, it is not easy to crack along a single cleavage plane. |
