Shenzhen Shenzhen drilling wells Shenzhen Shenzhen drilling Diamond drilling company structure right diamond drill bit gage material when drilling play a part in righting drill hole diameter to ensure that the role will not shrink. When using the method inserts at the sides of diamond drill gage achieve the purpose of the density and volume of diamond drill drilled according abrasive rock and hardness may be. For hard and abrasive formations with high quality diamond gage site should higher density should also be greater. Diamond drill bit cutter material material material cutter diamond drill into natural diamond and synthetic diamond into two categories, the first use of natural diamond and has been using synthetic diamond materials are polycrystalline diamond compact (the PDC) and thermal stability of poly Polycrystalline diamond (the TSP). They are called the drill made of diamond drill (or natural diamond drill), PDC drill bits and TSP. Crystal diamond is carbon crystal structure of a regular tetrahedron, a covalent bond between the carbon atom attached to the structure is very stable, there is a typical crystalline cube, octahedron and dodecahedron so on. Diamond is a human hardest material currently known, the compressive strength of the strongest, highest wear resistance material, so it is ideal as a drill blade material. However, the diamond drill cutting edge material as there is a big weakness. First, it's brittle, impact loads encountered cause rupture. Second, its thermal stability is poor, the diamond will burn at high temperatures and carbon monoxide into carbon dioxide, "in the air, between about 455 ~ 8601C, the diamond will appear in the burning of the stone S> in an inert or reducing gas not oxidized in the combustion, but at about 1430X:?, the diamond crystals would suddenly burst into a graphite Thus, diamond bit design, manufacture and use must be avoided in the diamond material is subjected to high impact loads and to ensure timely diamond cutting teeth cool down. Natural diamond drill with naturally occurring diamond particles as cutting edge. By species can be divided into Capone (Carbon, also known as black diamond), Buras (Balias), B?l?i (Boarz) and Congolese diamond four. Diamond weight grate, internationally accepted unit is carat, one karat equivalent 0. 2 g. Oil well drilling diamond particle size range is generally between 0.5 per carat to 15 per carat. Diamond drill must be solid texture, regular shape, such as a dodecahedron, octahedral, cubic or other shape close to a sphere. Due to limited sources of natural diamonds and expensive, foreign developed rapidly in the development of synthetic diamond. The first step is to drill synthetic diamond graphite under the action of some metal catalyst, in 5 ~ 10 MPa pressure and 1 0001C ~ 2 000X: made of single-crystal diamond under high temperature conditions. Has been able to synthesize 3 ~ 6 mm in diameter or larger single crystal diamond large particles, but the cost is higher. Less than 0. 5 mm diameter diamond has been able to mass production, crystal shape and intensity have been approached or reached after natural diamond sorting.
