Products Description LEANOMS
The Diamond Core Drill Bits are advanced drilling tools specially designed for geological exploration, mineral exploration, and engineering core sampling. This kind of drill bit usually consists of a drill bit steel body made of high-strength alloy steel and the structure is precisely designed to cope with the high hardness and wear resistance requirements under different geological conditions. The cutting part consists of diamond flakes or particles used to cut and break rock, ensuring efficient core sampling.
Material LEANOMS
The cutting materials of Diamond Core Drill Bits include a variety of high hardness and wear-resistant materials that work together to ensure efficient core sampling under different geological conditions. Here are some of the common cutting materials:
Carbide (tungsten carbide cutting tools): Carbide (tungsten carbide cobalt-based alloy) is often used as the base material for the body and teeth of drill bits. Cemented carbide is a material sintered from metal powders such as tungsten carbide particles (WC) and cobalt (Co). It has high hardness and wear resistance and is suitable for rock cutting and crushing.
Diamond (diamond flakes or particles): Diamond is one of the hardest natural materials and is often embedded in the cutting surface of a drill bit in the form of flakes or granules. Diamond has excellent cutting capabilities and is particularly suitable for processing extremely hard rocks and ores.
Composite blade (multi-layer blade): Some advanced diamond core drill bits use a composite blade design, which combines diamond with other materials in layers. This design not only improves cutting performance, but also can better cope with different rock properties.
Polycrystalline (polycrystalline diamond): Drill bits often contain agglomerated diamond particles within their matrix structure, and this material is synthesized through a high-temperature and high-pressure process. Polycrystalline diamond has a uniform structure and highly controllable hardness, making it suitable for the production of overall matrices and improving overall wear resistance.
The ingenious combination and application of these cutting materials enable diamond core drill bits to exert excellent performance in the fields of core sampling and geological exploration, ensuring efficient and reliable drilling operations.
Product structure LEANOMS
Diamond core drill bits may encounter some common failure problems during use. The following are some possible failure analyzes and corresponding solutions:
Diamond pieces fall off:
Failure analysis: Diamond chips may fall off due to strong impact force or wear of cuttings during the drilling process, resulting in a decrease in cutting effect.
Solution: Improve the fixation strength of diamond sheets, improve the diamond welding process, and use more wear-resistant diamond materials.
The steel body of the drill bit is deformed or broken:
Failure analysis: The steel body of the drill bit may be deformed or broken due to excessive impact or torque.
Solution: Optimize the design of the drill bit, enhance the strength and durability of the drill bit steel body, and ensure that it can withstand the pressure under various geological conditions.
Cooling system failure:
Failure analysis: The cooling system may fail due to water inlet blockage, pipe wear or insufficient coolant, causing the drill bit to overheat.
Solution: Clean the water inlet and cooling channel regularly to ensure smooth flow; choose corrosion-resistant, high-temperature coolant; improve the efficiency of the cooling system.
The connection thread is damaged or loose:
Failure analysis: The connecting thread may be damaged or loose after long-term use, reducing the stability of the connection.
Solution: Regularly check the wear degree of the connecting threads and replace damaged connecting parts; use high-strength connecting thread design to improve the reliability of the connection.
Matrix structure wear:
Failure analysis: The matrix structure may cause the diamond particles to fall off or the structure to become loose due to long-term wear.
Solution: Optimize the selection of matrix materials and use more wear-resistant materials; rationally design the matrix structure to improve its wear resistance.
