Custom Brass Bushings CNC Machining Process
People know the brass bushings for its superior strength, excellent machinability, and outstanding mechanical characteristics.
Dazao offers diverse CNC machining and metalworking services to produce components. Typical processing techniques encompass:
Features and Advantages of Brass Bushings
Low Friction & Anti-Galling：Natural self-lubrication prevents surface welding (galling) during dry starts or high-frequency oscillation, ensuring smooth movement even under marginal lubrication.
Sacrificial Wear Protection：Designed as a replaceable wear element; its controlled hardness protects expensive precision machined shafts from direct abrasion, significantly lowering long-term maintenance costs.
High Thermal Conductivity：Rapidly dissipates friction-generated heat away from the contact interface, preventing thermal expansion of the shaft and maintaining lubricant integrity under continuous load.
Superior Dimensional Stability：CNC-turned brass maintains strict ±0.01mm tolerances and Ra 0.4 finishes, offering far better structural rigidity and heat resistance than molded plastic alternatives.
Corrosion & Non-Sparking Properties：Naturally resistant to oxidation and moisture; its non-magnetic and non-sparking nature is essential for volatile, marine, or sensitive electronic environments.
Vibration & Noise Damping：The material density provides high damping capacity, absorbing micro-vibrations and reducing mechanical resonance in high-speed automated machinery.

FAQs About Brass Bushings CNC Machining
01.What are the load-bearing advantages of CNC brass bushings over plastic?
Brass bushings offer superior thermal conductivity and structural rigidity under heavy loads. Unlike plastic, CNC machined brass maintains dimensional stability at high temperatures (up to 200°C) and resists deformation under high-pressure mechanical stress, ensuring longer uptime in industrial gearboxes and motors.
02.Do your self-lubricating brass bushings require external grease?
While our high-purity brass alloys have natural low-friction properties, we can machine internal oil grooves or integrate graphite plugs for true self-lubricating performance. This reduces maintenance intervals in "fit-and-forget" applications like automotive hinges or automated assembly lines.
03.Can you manufacture flanged brass bushings to custom dimensions?
04.What is the typical MOQ for custom brass motor bushings?
05.What surface finishes are available for copper brass bushings?
06.How do you ensure the concentricity of thin-walled brass sleeves?
