Classification of Diamond
Diamond Raw Material
ND is the hardest substance of the known mineral at present. After grinding the natural diamond tool, The minimum radius of arc is R0.005mm, and the contour overall waviness is less than 50 nm . Application:precision and ultra-precision processing. optical processing and can get high-gloss surface.
MCD is a kind of diamond which is recrystallized by graphite powder and alloy
catalyst under high temperature and high pressure.
Application: polishing tool, wear resistant tool and optical processing tool.
CVD diamond is the symthesis of diamond films on heterogeneous substrates by chemical vapor deposition.CVD diamond is as same as the structure and properties ofmatural diamond.
Application: precision and ultra-precision processing, optical processing.
Polycrystalline diamond is intered from diamond powder with high temperature and high pressure. And are widely used in manufacturing industry.
Application: non-ferrous metals, carbide,ceramics, nonmetallic materials.
Diamond Crystal Selection
There are (100),(110) and (111) three main crystal orientations, of which (100) is the most difficult to wear, so we choose (100) crystal orientation as the rake surface and flank surface of the diamond tool.
The basic unit of a diamond is a face-centered cube. A large number of basic units are arranged in an orderly y manner to form the crystal form of a diamond There are three types of diamo nd crystal structures.
