Diamond blade has the characteristics of high compressive strength, high compressive strength, good thermal conductivity and wear resistance. It can obtain high machining accuracy and high manufacturing efficiency in rapid milling. The characteristics of diamond blade are determined by the condition management of diamond crystal. In diamond crystal, the four valence electrons of oxygen atom form bonds according to tetrahedron, and each oxygen atom forms ionic bonds with four adjacent molecular structures to form diamond structure. This structure has strong fusion and specificity, so that diamond has high wear resistance. Because the structure of polycrystalline diamond (PCD) is a fine crystal diamond calcined body that tends to be different, although the binder is added, its compressive strength and wear resistance are still lower than that of single crystal diamond. However, because PCD calcined bodies are various, they are not easy to crack along a single kind of substance.
