Custom Brass Parts: Why CNC Turning Is the Best Approach

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:

Medical connector components: Turned from CW614N brass, ISO 13485 certified, tight concentricity

Prototype power sensor housings: Delivered within 5 working days, with CMM inspection

Brass thread inserts: Produced in batches of 500–5,000, with custom knurling and slotting features

Instrumentation plugs: Small run production with ±0.01mm tolerance for industrial test systems

This experience allows us to handle everything from brass prototyping to repeat low-volume manufacturing of functional brass parts with complete traceability.


Certified Production with Full Documentation and Support

Our entire workflow is built to serve industries that require verified, documented quality:

  • ISO 9001:2015 and ISO 13485:2016 certified systems

  • Short runs starting at 1 piece, up to 10,000+

  • Response time within 12 hours, with full DFM support for new designs

We position ourselves as a CNC machining expert focused on brass parts, not just a general-purpose shop. Each part is traceable, inspected, and optimized for cost-performance ratio.


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.
