H59 CNC Milling Brass Bushing High Quality CNC Machined Parts Custom Machining
We select premium materials such as H62, H65, HPb59-1, and environmentally friendly lead-free brass, and professionally manufacture high-precision brass bushings through CNC precision machining. Brass possesses excellent machinability, good self-lubricating properties, and corrosion resistance. Through CNC machining and appropriate surface treatment processes, we achieve a balance between precision internal bore forming, oil groove design, and long-term wear resistance, making it an ideal choice for manufacturing rotating support systems with high requirements for smooth motion, electrical conductivity, and friction reduction.
Each brass bushing undergoes CNC precision machining to ensure micron-level internal bore roundness, precise external diameter positioning, and optimized oil groove distribution. Optimized structural design and strict tolerance control ensure the coaxiality and lubrication performance of the bushings during high-speed operation, effectively reducing the coefficient of friction and improving equipment stability and service life.
By selecting HPb59-1 leaded brass or environmentally friendly lead-free brass, combined with scientific cutting processes and precision machining, CNC-machined brass bushings achieve precision requirements such as inner hole roundness ≤0.005mm, coaxiality ≤0.008mm, and surface roughness Ra≤0.4μm. Simultaneously, relying on the self-lubricating properties of brass and optimized oil groove design, they withstand long-term rotational motion, frictional wear, and alternating loads.
We use multi-axis CNC machine tools and automated production lines to ensure that every brass bushing meets stringent geometric accuracy and assembly requirements. By integrating a CAD/CAM system for machining simulation and process optimization, combined with professional stress relief, CNC precision turning, milling, and surface treatment processes, we have achieved an optimal balance between precision fit, oil groove structure, and wear resistance.
We are committed to providing high-quality brass bushing solutions for the precision machinery and electrical industries through advanced material applications, CNC machining technology, and rigorous quality management.
