Diamond Compact (PDC) is a superhard composite material composed of a polycrystalline diamond layer (PCD) and a cemented carbide substrate. Geological PDC is mainly used for geological drilling bits. Suitable for all kinds of geological development drilling. For example wells drilling, mining drilling, etc.

The role of drilling in oilfield development is very important. It is estimated that drilling investment accounts for 35% to 40% of investment in certain fields. At present, the oil resources of various countries in the world are depleting. This requires drilling companies to carry out oil development more economically and efficiently. As the most important tool in drilling operations, the bit performance directly affects the quality, cost and efficiency of drilling operations. In the 1980s, people developed a polycrystalline diamond compact bit (PDC drill bit) using artificial polycrystalline diamond as a cutting tooth, which can significantly improve the drilling efficiency and have a long service life, and has been widely used. application.

Polycrystalline diamond, abbreviated as PCD, normally called PCD blank, which is made by synthetic diamond micron powder are the high temperature and pressure sintering production environment. DIAMONDWK Wire Drawing Die PCD Blanks have not only high wear resistance, hardness, and thermal conductivity, but also high mechanical strength and tenacity.

There are two kinds of diamond wire drawing die, one is natural diamond die. The other is synthetic polycrystalline diamond die. Natural diamond has the characteristics of high hardness and good wear resistance. The surface drawing wire is with very high finish. Due to the anisotropy of natural diamond structure, its hardness is also anisotropic, which makes the wear of the die hole uneven. The product is not round, plus expensive, rare, generally used as a surface quality high demand for fine wire drawing die or finished drawing die. Synthetic polycrystalline diamond is an unoriented polycrystal, which has the advantages of high hardness, good wear resistance and strong impact resistance.

PCD cutting tool blanks are produced by sintering selected high purity and hardness diamond particles at high pressure and high temperature. PCD cutting tools blanks provide great hardness, abrasion resistance, and thermal conductivity. PCD (polycrystalline diamond) cutting materials in disc and cut-segment formats for the precision tooling industry. For the production of super-finishing, finishing and roughing metal forming tools, dressing tools, measuring instruments or support tools, etc resistant materials. PCD is widely used for the machining of non-ferrous metals and alloys, such as aluminum, copper, aluminum / gray iron composites, as well as nonmetallic materials such as wood, chipboard, ceramics, plastic, rubber etc, where high abrasion resistance and good surface finish are required.

Widely used in non-ferrous metals and alloy processing, such as aluminum, copper, aluminum / iron-gray composite, and non-metallic materials wood, chipboard, ceramics, plastic, rubber, etc. where high abrasion resistance and good surface finish are required.

Diamond micron powder is the use of high-quality diamond as raw material, through the integer, grading and purification and other strict standardized process from the particle size of 0.1-54 microns. There are single crystal diamond powder and polycrystalline diamond powder. Monocrystalline diamond micron powder: selection of large particles of diamond as raw materials, after crushing, integer, purification, purification, separation, drying, particle size analysis and other technology made. Single crystal diamond powder is yellow or off-white powder, uniform size, high strength, low impurity content.
