Processing Technologies for Multifunctional Anchoring Drilling Rig Accessories

Multifunctional anchoring drilling rig accessories, including drill bits, drill rods, anchor rod joints, hydraulic valve groups, and wear-resistant sleeves, adopt advanced precision processing and surface modification technologies to adapt to high-strength drilling, anchoring, and complex stratum construction conditions. For core load-bearing accessories such as drill rods and anchor connectors, manufacturers apply integral forging and CNC precision turning technologies. 

Integral forging eliminates internal material pores and cracks, improving the overall structural strength and fatigue resistance of accessories, while CNC turning ensures precise dimensional tolerance, achieving accurate docking and stable transmission of drilling torque. Hard rock drill bits adopt vacuum brazing and carbide inlay technology, fixing high-hardness tungsten carbide alloy teeth on the bit matrix to enhance rock breaking efficiency and wear resistance. Surface processing technologies are critical for accessory durability: high-frequency quenching technology is used for the outer wall of drill rods and wear parts to form a high-hardness wear-resistant layer on the surface while maintaining the toughness of the inner matrix, effectively resisting stratum friction and impact wear. In addition, shot blasting and anti-corrosion spraying technologies are applied to metal accessories to remove surface oxide scales and form a protective coating, avoiding rust and corrosion in humid foundation and slope construction environments. 

For precision hydraulic accessories such as valve cores and sealing rings, fine grinding and imported high-precision mold injection molding technologies are adopted to ensure sealing performance and hydraulic transmission accuracy. Some high-end accessories also adopt laser cladding technology, cladding high-wear-resistant alloy materials on vulnerable parts to extend service life. These integrated processing technologies ensure the high precision, high strength, and high durability of anchoring drilling rig accessories, meeting the multi-scenario construction requirements of foundation anchoring, slope support, and tunnel reinforcement.
