Single crystal diamond


Single crystal diamond cutting tools must be used for large particles (mass greater than 0.1g, the best path length not less than 3mm), mainly used in surface

roughness, geometry, high precision and dimensional accuracy requirements of precision and ultra precision machining applications fields.
Natural diamond single crystal diamond is the most wear-resistant material. Fine texture of its own, after fine grinding, cutting edge edge edge radius as small as

0.008 ~ 0.005μm. But more brittle natural single crystal diamond, the crystal anisotropy, different surfaces or in the same plane

Crystal hardness in different directions were different, and must be used during the sharpening choose the right direction. The use of harsh conditions, coupled with

natural single crystal diamond resources are limited, the price is very expensive, so they use a production PCD, PCD / CC and CVD diamond

Tools. Some natural single crystal diamond is mainly used for ultra-precision machining non-ferrous metals or gold jewelry production.
synthetic diamond single crystal diamond the size, shape and performance are in good agreement, present due to high pressure technology matures, a certain size can be prepared

by synthetic single crystal diamond, especially in the processing of high wear-resistant laminated wood, it performance to be

Than PCD diamond cutting edge will not cause premature passivation
