<<Polycrystalline Diamon t;>
Polycrystalline Diamond is manually produced in the way of high pressure and high temperature. It is broadly applied in all kinds of industrial processing. Its hardness is HV6, 500~HV8, 000. It is 80~120 times as hard as hard alloy. The specialties of Polycrystalline Diamond are high heat conduction (700W/mK), low Coefficient of thermal expansion (0.9×10), high abrasion resistance, and quite low friction coefficient.
Polycrystalline Diamond can be classified into two types---PCD and CVDD. PCD is formed by high pressure and high temperature. By using cobalt as accelerant, grains will cohere to Tungsten Carbide or be wrapped by Tungsten Carbide, then, it is put in high pressure device and heated; after being sintered, it becomes a composite. PCD shows no sequence, no aspect, and even hardness.
Polycrystalline Diamond has the following advantages:
1. Under big impact, Polycrystalline Diamond only produces some little crystalline grains.
2. Polycrystalline Diamond can be used in bigger cutting tools, such as milling cutters.
3. Polycrystalline Diamond can be produced into specially designated shapes for different processing demands.
4. Specific functions can rendered to cutting tools by Polycrystalline Diamond to fit their specific applications.
Polycrystalline Diamond is usually used to do precision cutting and half-precision cutting, rough cutting,and non-successive cutting (such as milling). Polycrystalline Diamond has extended the application scope of diamond cutting tools.
The applications of Polycrystalline Diamonds are Non-Ferrous Metal, Non-Metal Material, ex.: aluminum alloy, copper and its alloy, carbon/graphite, plastic, plastic/complex materials, and etc.
