Brass CNC Machining Services & Custom Brass Parts
We review custom brass parts for CNC turning and milling, including bushings, spacers, fittings and small mechanical components. C36000 and CW614N are grade references to discuss against the exact drawing and application.
Start with the application.
State the application, alloy and any restrictions on composition. Do not substitute an apparently equivalent grade without confirming the relevant material specification.
Typical uses: Bushings, spacers, fittings.
Grades are inquiry references. Supply, condition and suitability are confirmed in the quotation.
Ask about Brass
Quote a brass component by its working features
A fitting may be defined by its thread and sealing face; a bushing by its bore and outside fit. Identify those features before discussing decorative polishing. This keeps the quote focused on the features you will actually accept at delivery.
| Component | Specify first | Then review |
|---|---|---|
| Bushing | Inside and outside fits, length, installation condition | Wall thickness, clamping and measurement method |
| Threaded fitting | Thread designation, engagement and sealing arrangement | Wrench flats, cross-holes and deburring access |
| Spacer | Length limits, bolt clearance and contacting faces | Quantity per length and any marking |
| Visible machined detail | Critical geometry and visible faces | Polish reference and edges that must remain defined |
C36000 and CW614N: use the exact specification
Keep the designated alloy and applicable material standard in the drawing and quotation. Do not switch between names simply because both appear in a free-machining brass catalogue. Where composition restrictions matter, state them with the material requirement and request the corresponding records. That is particularly important when a general-purpose component is being adapted to a different end use.
Our recommendation is to agree the material before approving the functional sample. A sample made in one grade leaves the effect of a later substitution unresolved, even when the dimensions match. If your application needs a different brass alloy, list it explicitly in the inquiry.
Example: a threaded brass adapter
In a drawing-review example, an adapter has two different threads and a hexagonal grip. The model shows the outer shape but the PDF specifies only one thread. The missing designation prevents an unambiguous quote: the second thread’s standard, pitch, fit and usable length still need to be selected. Add a section view if the internal passage or sealing shoulder is hidden.
Include the mating-part references and say which surfaces seal. For a sample order, test both interfaces before moving to the repeat batch. Our CNC turning service covers the relationship between diameters, threads and secondary features.
Polishing, inspection and delivery records
Mark the faces for polishing and any edges or fitted surfaces that must remain unchanged. Decide how visible marks will be judged and which dimensions need a record. A photo of a bright fitting explains appearance; it does not specify the bore fit or thread acceptance.
For a quote, send the current STEP and PDF, material specification, quantity by part number, finish and delivery country. Production orders start at 100 pieces per part number, counted separately for each part. Prototypes and sample parts are quoted from a single piece. Design-only projects are quoted separately. Ask for material documentation and thread or dimensional inspection records as part of the agreed inspection scope.
SURFACE OPTIONS
Plan the finish with the material.
Polishing
Improves the appearance of selected surfaces through mechanical finishing.
Include these details in your inquiry
| Requirement | What to include |
|---|---|
| Designation | Grade, material standard and required condition |
| Application | Environment, mating materials and functional constraints |
| Finish | Appearance reference, masking and critical dimensions |
| Records | Any material or inspection document required with the order |
YOUR QUESTIONS, ANSWERED
A clearer path
to your next part.
Find practical answers before starting a project.
Can you recommend a material or finish?
Choose “Help me choose” in the inquiry. Explain the application and environment so the options can be reviewed against the function of the part.
What if I need a particular inspection report?
Name the document and the features or tests it must cover in the inquiry. Its availability, scope and cost need to be agreed before the order.
Specifying a machined brass surface?
Bushings, spacers and fittings often carry a functional surface requirement. The surface roughness reference covers Ra and Rz, unit conversion and what makes a callout measurable, then take it into CNC turning.
