Synthetic polycrystalline diamond


Synthetic polycrystalline diamond of the diamond with a binding agent at high temperature under high pressure sintered diamond polymer which has a very high heat

resistance and high thermal stability. Widely used in manufacturing petroleum, geological drill bits, diamond processing and machining tools.
Classification
Polycrystalline Diamond for petroleum and geological drill into the TSP series and for diamond processing of polycrystalline diamond series:
Synthetic polycrystalline diamond TSP: ① the diamond mainly inert binding agent and the diamond particles made of high temperature and pressure conditions. At the

same time due to the thermal expansion coefficient of the binder close to the diamond, so the heat resistant temperature of 1200. C or so. ② It has high wear ratio,

also known as thermally stable polycrystalline compared to the cost of natural stone at a very low cost, is the production of petroleum geology drill the ideal

material. The same can also be used for grinding.
synthetic diamond polycrystalline diamond polycrystalline diamond: ① mainly by diamond and binding agent in the high temperature / high pressure sintering. ② It is much

lower than the wear than the TSP series, compared to the natural diamond has a higher grinding efficiency, with unparalleled price advantage, has become the inevitable

rough diamonds, is very conducive to a variety of processes of grinding and polishing . Polycrystalline diamond can precisely control the wear ratio, can adapt to

different processing requirements. Since all manufacturers use different formulations and processes, so the production process and durable effect is different.
Feature
Polycrystalline Diamond PCD: hardness high wear resistance and impact toughness.
Polycrystalline diamond TSP: ① has good thermal stability and higher impact strength and better wear resistance; ② than it consumes up to 30,000 ~ 100,000; ③ can

meet a variety of complex underlying drilling needs.
Use
Polycrystalline Diamond Polycrystalline Diamond Series (Po polycrystalline):
Since hardness for natural diamond polishing and edge to the machining tool. Oil drill cutting elements, suitable for soft to medium hard formation drilling, machining

tool can also be used as a cutting edge for cutting non-ferrous metals and non-metallic materials. Products can be processed into the desired size and shape of the

user.
Polycrystalline diamond TSP Series:
For oil drilling, geological exploration, drilling small diameter polycrystalline insurance cost compared to natural diamond and very inexpensive, high wear

resistance. Products can be processed into the desired size and shape of the user.
Because two kinds of polycrystalline polycrystalline diamond and TSP hardness and wear resistance effect is not the same, so the degree of processing polycrystalline

diamond is very different.
Shape
Polycrystalline diamond with a triangle, square, rectangular, cylindrical, both ends of the arc-shaped, and its diversification tool for a variety of drilling and

geological requirements.
