What are the characteristics of natural surface mount hole openers
The natural surface mount reamer has the following characteristics:
1. High wear resistance: The body of the reamer is usually uniformly mixed with some micro polycrystalline particles, such as 150-200 mesh micro artificial diamond polycrystalline particles, while natural diamond particles are regularly and orderly embedded on the surface of the body. These natural diamonds have high hardness and
The natural surface mount reamer has the following characteristics:
1. High wear resistance: The body of the reamer is usually uniformly mixed with some micro polycrystalline particles, such as 150-200 mesh micro artificial diamond polycrystalline particles, while natural diamond particles are regularly and orderly embedded on the surface of the body. These natural diamonds have high hardness and strong wear resistance, which can effectively resist the grinding effect of the formation, reduce the wear of the reamer during drilling, and thus extend its service life.
2. Good drilling performance: Natural diamonds have good cutting performance and can effectively break rocks during drilling. The diamond particles embedded on the surface can directly come into contact with the rock, and applying less pressure can generate greater cutting force, thereby improving the drilling speed. In addition, some natural surface mounted hole openers are designed with special structures, such as hole openers with guiding spiral edges. The guiding slopes and spiral edges on the body of the hole are conducive to crushing rock debris, reducing drilling resistance, making the hole opener more stable during drilling, and further improving drilling efficiency.
3. Strong geological adaptability: Natural diamonds with different particle sizes, concentrations, and arrangements can be selected for surface setting according to different geological conditions to meet the drilling needs of various complex formations. For example, for formations with higher hardness, diamonds with larger particle size and higher concentration can be selected; For fractured formations, a special diamond arrangement can be used to enhance the stability and adaptability of the reamer.
4. Long working life: Due to the high hardness and wear resistance of natural diamonds, as well as reasonable tire body design and manufacturing processes, natural surface mounted hole openers can maintain good performance under normal use conditions and have a long working life. When drilling into fractured formations, some high-quality natural surface mounted hole openers can have a service life of over 3200 meters, while surface mounted natural diamond hole openers with guiding spiral edges can have a service life of about 3670 meters when drilling into fractured formations, significantly reducing drilling costs compared to ordinary hole openers.
5. Good dimensional stability: During the manufacturing process, natural surface mounted hole openers can ensure their dimensional accuracy and stability through correct processing techniques and quality control. This helps to maintain the uniformity of the diameter of the borehole during the drilling process, avoiding situations where the aperture expands or shrinks, and providing good conditions for subsequent drilling work.
