CNC Boring Bronze

CNC Boring Bronze is a core capability at VT machining. We combine controlled turning with material-aware setup for Bronze — an alloy that is wear resistant with good bearing properties — to produce parts that meet your specification first time.

CNC Boring Capability for Bronze

• Bore tolerance to IT6
• Roundness within 0.005 mm
• Fine boring heads
• Large-diameter capability

How CNC Boring Bronze Works

The Bronze bar or billet rotates in the spindle while single-point tools shape outer diameters, bores, faces, grooves and threads. Constant surface speed control keeps cutting conditions stable from large to small diameters.

Programming is driven directly by your 3D model or print. Work-holding, tool selection and the cutting strategy are planned around the critical features and the material before the first chip is cut. First-off inspection confirms the process is centred before production continues.

CNC Boring Tolerances & Surface Finish

Turned Bronze 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.

Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.

Working with Bronze

As a material, Bronze is wear resistant with good bearing properties. Our setup reflects the alloy's machinability so the finished part is accurate and free of avoidable defects.

We verify the exact grade and condition before machining, and traceable mill certs are available on request. We can work to your nominated material source or specification when required.

Secondary Operations & Finishing

Finished Bronze parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.

CNC Boring Quality & Inspection

We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every Bronze part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.

Design Tips for CNC Boring Bronze

We are happy to suggest design tweaks that improve manufacturability. Consistent diameters, standard thread forms and avoiding extremely long, slender features help Bronze turned parts stay concentric and economical. If you send your model early, we will return practical DFM feedback before you commit to production.

Applications of CNC Boring Bronze

Customers order CNC Boring Bronze components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.
