High-precision 5-axis CNC machining services for brass rotary shafts

Ganyuan Factory has focused on manufacturing brass rotary shafts for over twenty years. Relying on high-precision CNC machine tools and professional testing processes, we strictly control the concentricity, surface finish, and wear resistance of the shafts, ensuring they possess excellent electrical conductivity, a low coefficient of friction, and smooth transmission performance.

Product description

CNC Machining Endows Brass Rotary Shafts with Exceptional Performance

In precision instruments, high-end valves, and professional transmission systems, brass rotary shafts, with their excellent electrical and thermal conductivity, outstanding wear resistance, and good machinability, are the ideal choice for precision rotating components. Leveraging over twenty years of CNC precision machining experience and a deep understanding of brass material properties, we provide comprehensive solutions for the precision manufacturing of rotary shafts, from material optimization to process implementation.

I. Perfect Realization of Precision Rotation Features

The core performance of a rotary shaft depends on its roundness, coaxiality, and surface quality. Using high-precision CNC lathes and customized tooling systems, and through intelligent cutting parameter control, we can stably control the roundness error of the shaft within 0.005mm, and achieve a surface roughness of Ra0.4μm for key mating surfaces. For complex shafts with multi-step, irregular groove, or eccentric structures, all features can be machined in a single setup, maintaining coaxiality accuracy between features within 0.01mm, ensuring smooth and precise rotational motion.

II. Optimization of Brass Material Properties

We have developed a dedicated machining process database to address the cutting characteristics and mechanical properties of different brass grades. Through cutting temperature control and tool angle optimization, we improve machining efficiency while maximizing the balance between brass's ductility and strength. For applications requiring high conductivity, a special process protects the material's crystal structure, ensuring conductivity loss does not exceed 2%. For applications with high wear resistance requirements, surface micro-treatment technology is used to enhance surface hardness while retaining brass's self-lubricating properties.

III. Dual Guarantee of Thermal Stability and Dimensional Accuracy

Brass is prone to thermal deformation during machining, affecting long-term accuracy. We have established a constant-temperature machining environment, combined with micro-lubrication and layered cutting technology, to control the machining temperature rise within 5°C. For slender shafts with a length-to-diameter ratio greater than 10:1, a follow-tool system and reverse broaching process are used to effectively suppress tool deflection, ensuring that the straightness error of the shaft does not exceed 0.02mm/100mm across its entire length, meeting the dynamic balance requirements for high-speed rotation.

IV. Multifunctional Integration and Lightweight Design

Modern rotary shafts often require the integration of transmission gears, fluid channels, or sensor mounting structures. Our five-axis machining centers can precision-machine these complex features in a single setup. Through topology optimization and localized weight reduction, we achieve a 20%-30% weight reduction while maintaining structural strength, effectively reducing rotational inertia and improving system response speed.

In today's era of continuous advancements in precision transmission technology, brass rotary shafts are playing a crucial role in various fields due to their unique advantages. Through continuous innovation in CNC machining processes, we have not only achieved precision manufacturing of complex structures but also established new standards in material properties, dimensional accuracy, and long-term reliability. Every brass rotary shaft we process provides a solid foundation for the reliable operation of precision equipment with its superior rotational accuracy, stable transmission performance, and enduring durability.
