CNC Punching Bronze

VT machining provides CNC Punching Bronze for customers who need accurate, repeatable Bronze components. Because Bronze is wear resistant with good bearing properties, we adapt the process to suit — controlling the variables that matter for this alloy.

CNC Punching Capability for Bronze

• Sheet thickness 0.5–6 mm
• Hole position repeatability ±0.10 mm
• Punch/die clearance set per material
• Louver, emboss and tap-extrude tooling

How CNC Punching Bronze Works

A CNC turret presses hardened punches through the Bronze sheet into matching dies. Punch-to-die clearance is set as a percentage of thickness so the cut edge stays clean and burr is minimal.

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.

Design Tips for CNC Punching Bronze

We are happy to suggest design tweaks that improve manufacturability. Keeping hole-to-edge and hole-to-hole distances at least 1.5–2× thickness avoids distortion and tearing in punched Bronze. If you send your model early, we will return practical DFM feedback before you commit to production.

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.

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.

CNC Punching 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.

CNC Punching Tolerances & Surface Finish

Punched Bronze holds hole-position repeatability around ±0.10 mm across the sheet, with consistent hole quality when punch/die clearance is matched to the gauge.

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.

Applications of CNC Punching Bronze

Customers order CNC Punching 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.
