CNC Turning C377 Brass from VT machining delivers precision C377 Brass parts made to your exact drawing. CNC turning rotates the workpiece against a single-point tool to produce cylindrical features, threads and grooves, with parameters tuned to C377 Brass, which is free-machining with good conductivity.

Published typical values for C36000. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Nothing much — this is the easiest metal in the shop. Worth asking about if a copper or bronze part is cost-driven rather than conductivity-driven.
Machining C377 Brass with CNC Turning
The machinability of C377 Brass is excellent (free-machining); fast speeds, clean finish. For CNC Turning we select tooling, feeds, speeds and coolant to match, keeping the C377 Brass workpiece stable and the result accurate.
Because we machine C377 Brass regularly, proven settings shorten setup and keep quality repeatable across reorders.
Achievable Tolerances for CNC Turning C377 Brass
| Feature | Standard | Precision |
|---|---|---|
| Outside diameter | ±0.05 mm | ±0.005 mm |
| Bore diameter | H9 | H6 |
| Length / shoulder position | ±0.10 mm | ±0.020 mm |
| Concentricity OD to ID | 0.05 mm TIR | 0.010 mm TIR |
| Roundness | 0.02 mm | 0.005 mm |
| Thread class | 6g / 2A | 4h / 3A |
| Surface finish, as turned | Ra 1.6 µm | Ra 0.4 µm |
Standard is what a normal quotation assumes. Precision is available on nominated features and is priced separately, because it needs extra setups, in-process gauging and CMM verification. Call out only the features that need it — blanket-tightening a drawing is the single most common reason a quote comes back expensive.
Design Tips for CNC Turning C377 Brass
A few design choices make a real difference to cost and quality. Consistent diameters, standard thread forms and avoiding extremely long, slender features help C377 Brass turned parts stay concentric and economical. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Turning Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on C377 Brass parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
CNC Turning Tolerances & Surface Finish
Turned C377 Brass holds diameter tolerances to about ±0.005 mm with concentricity within 0.01 mm and good roundness. Turned finishes of Ra 0.4–0.8 µm are achievable with finishing passes and sharp tooling.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Why C377 Brass?

What We Need to Quote CNC Turning C377 Brass
- GeometrySTEP or IGES for the 3D model, plus a PDF drawing if you have tolerance callouts. A dimensioned sketch is enough to start.
- MaterialThe exact C377 Brass grade and condition — temper, heat-treat state or hardness. If you are not sure, tell us the function and we will suggest one.
- QuantityPrototype count and the expected annual volume. Both change how the part is made and therefore what it costs.
- TolerancesWhich features are critical. Everything else runs to our standard tolerance, which is what keeps the price sensible.
- FinishSurface treatment, cosmetic requirements, and any faces that must be masked.
- DocumentsWhether you need a material certificate, dimensional report, FAIR or PPAP with the shipment.
Missing something from the list is not a problem — send what you have. We will come back with the specific questions rather than a generic form.
