For over two decades, Ganyuan Factory has focused on precision machining, specializing in the manufacture of various high-performance brass knurled fasteners using advanced CNC machining technology. Equipped with high-precision multi-axis CNC machine tools and advanced coordinate measuring machines, we ensure that every knurled fastener machined from brass blanks achieves micron-level dimensional accuracy and stringent geometric tolerances from the very beginning.
CNC milling of brass knurled bolts Trustworthy custom metal parts manufacturing
We select high-quality H62, H65, HPb59-1, and environmentally friendly lead-free brass materials, and professionally manufacture high-precision brass knurled fasteners through CNC precision machining. Brass possesses excellent electrical and thermal conductivity, good machinability, and corrosion resistance. Through CNC machining and appropriate surface treatment processes, we achieve a balance between micron-level thread forming, knurling design, and long-term anti-loosening performance, making it an ideal choice for manufacturing various equipment with high requirements for fastening reliability, ease of manual operation, and corrosion resistance.
Each knurled brass fastener undergoes CNC precision machining to ensure a precise thread profile, accurate pitch, and clear knurling texture. Optimized structural design and strict tolerance control guarantee the fastener's anti-loosening reliability and ease of assembly under vibration and alternating load conditions, effectively improving the overall operational safety and maintenance convenience of equipment.
By selecting HPb59-1 leaded brass or environmentally friendly lead-free brass, combined with scientific cutting processes and precision machining, CNC-machined knurled brass fasteners achieve micron-level precision with a thread pitch diameter accuracy ≤0.005mm, a tooth profile accuracy ≤0.01mm, and a knurling module accuracy ±0.02mm. Simultaneously, relying on the excellent electrical conductivity and good corrosion resistance of brass, they can withstand long-term manual rotation, locking operations, vibration, impact, and humid environments.
We utilize multi-axis CNC machine tools and automated production lines to ensure that every knurled brass fastener meets stringent thread precision and appearance requirements. Through integrated CAD/CAM systems for machining simulation and process optimization, combined with professional stress relief, CNC precision turning, thread milling, knurling, and surface treatment processes, we have achieved the optimal balance between micron-level thread forming, knurling texture design, and corrosion resistance.
We are committed to providing high-quality knurled brass fastener solutions for the precision instrument and electronics industry through advanced material applications, CNC machining technology, and rigorous quality management.
