When manufacturing demands high dimensional accuracy, reliable conductivity, and consistent mechanical properties, custom brass parts are often the ideal choice. Brass’s machinability makes it compatible with complex part geometries, but to achieve repeatable, high-quality results, CNC turning remains the most efficient and cost-effective method for machined brass parts.It offers precision, speed, and flexibility—especially crucial for industries like electronics, automotive, and plumbing.
Brass Parts Are Widely Used Across Technical Applications
Brass components play a critical role in many industries where precision and stability are essential. Common applications include:
Electrical contact pins and terminals
Threaded fittings and inserts for plastic assemblies
Instrumentation sleeves, valve stems, and bushing housings
Miniature plumbing parts and fluid system couplings
Custom spacers, connectors, and switch housings
Thanks to its excellent machinability, brass parts are especially suitable for CNC turning processes that involve high repeatability, such as producing low-volume brass components or functional prototypes.
CNC Turning Offers Consistent Accuracy for Machining Brass
The CNC turning process is ideal for producing brass turned parts that demand dimensional precision and clean surface finishes. Key process advantages include:
Surface quality: Ra 0.8μm or better without secondary polishing
Tolerances: ±0.01 mm standard; ±0.005 mm achievable on request
Efficiency: Multi-axis lathes allow complex features (slots, cross-holes, undercuts) to be machined in one setup
Materials: We support machining of C3604, CW614N, C464, and other brass grades used in precision parts
Threading: Metric, BSP, UNF, and custom thread profiles available
If your design involves tight-tolerance or multi-feature brass parts, our CNC turning capability ensures the level of precision your application requires.
Clients Rely on CNC Turning for Custom Brass Part Production
Across our production history, we’ve handled a wide range of custom brass parts machining projects, including:

FAQs About CNC Brass Machining Service
What brass grades do you machine most frequently?
We commonly machine C3604, CW614N, and C464. Other grades like C3771 and lead-free options are available on request for specific brass parts.
Do you provide inspection reports or quality documents?
Yes. Every order includes visual and dimensional checks. Full FAI, CMM, and certificates can be provided for all custom machined brass parts.
What’s your typical lead time for CNC brass parts?
Prototypes and low volumes (<100 pcs) ship in 5–7 days. We also support urgent delivery cases.
Can you machine threads or knurled features?
Yes. Both internal and external threading, knurling, slotting, and undercuts are supported in our brass turning process.
Do you work with customer drawings and models?
Absolutely. We accept 2D/3D files in all formats and provide DFM feedback if needed.
Tips to Optimize Cost for Brass CNC Turning
To minimize unit cost and lead time in brass CNC machining, consider the following:
Avoid very deep holes (>3× diameter)
Use standard metric or UNF threads
Choose machinable alloys like C3604
Limit unnecessary tight tolerances
Minimize asymmetry and complex undercuts when possible
These strategies help optimize both tooling time and machining efficiency, especially important in cost-sensitive brass part production.
