Brass CNC turned bush

We manufacture high-precision CNC turned bushes using premium brass alloys, designed to provide a reliable and low-friction interface for rotating shafts, pins, and components in mechanical assemblies. By combining the natural benefits of brass with the accuracy of CNC machining, these bushes deliver superior concentricity, tight tolerances, and excellent surface finish . Whether you require a simple sleeve, a flanged design, or a custom thread, our turned bushes are the ideal solution for applications demanding durability and precision .

Key Benefits & Material Properties
Brass is the material of choice for turned bushes due to its unique combination of mechanical and physical properties .

Superior Machinability: Brass, particularly free-machining grades like C36000, allows for high cutting speeds, reduced tool wear, and the creation of complex geometries with excellent detail .

Natural Lubricity: Brass offers inherent self-lubricating properties, which helps reduce friction against steel shafts, minimizing wear and ensuring smooth, quiet operation even in borderline lubrication conditions .

Excellent Corrosion Resistance: Naturally resistant to rust and corrosion, brass performs exceptionally well in moist environments, plumbing systems, marine applications, and industrial fluids .

Dimensional Precision & Stability: CNC turning ensures that every bushing meets tight dimensional tolerances (up to ±0.01mm or tighter), guaranteeing a perfect fit and consistent performance across high-volume production runs .

Manufacturing Process: The Art of CNC Turning
Creating a precision brass bushing involves a meticulous multi-step CNC turning process :

Material Preparation: High-quality brass rods or bars are loaded into a CNC lathe, often using an automatic bar feeder for efficient, continuous production.

Facing & Centering: The end of the bar is faced to create a perfectly flat reference surface. A center drill ensures that all subsequent operations are perfectly coaxial.

Rough & Finish Turning: The outer profile (OD) is shaped using carbide tools. A roughing pass removes excess material, followed by a finishing pass that achieves the final dimensions and a smooth surface finish.

Internal Machining: Precision drilling creates the internal bore. For applications requiring extremely tight internal diameter (ID) tolerances, a boring bar is used to enlarge and fine-tune the hole to its exact final size.

Parting & Deburring: A parting tool separates the finished bushing from the raw bar stock. Finally, all sharp edges are carefully deburred through tumbling or manual processes to ensure safe handling and a professional finish .

Applications Across Industries
Brass CNC turned bushes are versatile components found in a wide range of industries :

Automotive: Gearbox components, pedal bushings, steering column bushes, and engine control linkages .

Plumbing & Valves: Guide bushes for valve stems, faucet components, and pipe fitting supports .

Electrical & Electronics: Mounting bushes for terminals, switches, and connector housings, utilizing brass's excellent conductivity .

Industrial Machinery: Wear bushes for conveyor systems, pivoting points in agricultural equipment, and guide elements in packaging machines .

General Engineering: Spacers, sleeves, and custom threaded inserts for various mechanical assemblies.

Quality Assurance and Customization
We ensure every brass turned bushing meets rigorous quality standards:

Dimensional Inspection: Parts are verified using coordinate measuring machines (CMM), micrometers, and pin gauges to ensure adherence to specified tolerances .

Material Certification: We provide certifications confirming the chemical composition and mechanical properties of the brass alloy used .

Surface Finishing: A variety of post-machining finishes are available, including polishing for a glossy look, nickel/chrome plating for enhanced corrosion resistance, and passivation for cleaning .

Custom Specifications: We welcome custom designs. Whether you need a specific flange diameter, a unique length, or secondary operations like milling or cross-drilling, we can manufacture bushes to your exact CAD specifications
