CNC Sinker EDM Bronze

CNC Sinker EDM Bronze from VT machining delivers precision Bronze parts produced to your exact drawing. Sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features, and we tune every parameter to the behaviour of Bronze, which is wear resistant with good bearing properties.

CNC Sinker EDM Capability for Bronze

  • Blind cavities & ribs
  • Fine surface (VDI grades)
  • Tolerance to ±0.005 mm
  • Hardened tool steel

How CNC Sinker EDM Bronze Works

Material is removed from the Bronze workpiece by controlled electrical discharges across a dielectric gap, with no mechanical contact. Flushing, on/off pulse timing and electrode/wire feed are set to balance speed against surface finish.

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 Sinker EDM Bronze

We are happy to suggest design tweaks that improve manufacturability. EDM suits sharp internal corners, thin ribs and hardened Bronze that cannot be milled; allowing a small corner radius where possible speeds the cut. 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.

CNC Sinker EDM Tolerances & Surface Finish

EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the Bronze part, producing fine, controlled surface textures and sharp internal corners impossible to mill.

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.

CNC Sinker EDM 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.

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.

Frequently Asked Questions

What surface finish is achievable on Bronze with CNC Sinker EDM?

Surface finish on Bronze is controlled to your specification; we confirm the achievable Ra against your callout.

Why is Bronze a good choice for CNC Sinker EDM?

Bronze is wear resistant with good bearing properties, which makes it well suited to CNC Sinker EDM. We tune the process to the alloy so the finished Bronze EDM machining part meets your dimensional and functional requirements.

What tolerances can you hold for CNC Sinker EDM Bronze?

Achievable tolerances for Bronze EDM machining depend on the alloy, geometry and feature size. EDM holds tolerances to around ±0.002 mm with no cutting force on the part. Exact figures are confirmed against your drawing callouts.

What is the typical lead time and minimum order for CNC Sinker EDM Bronze?

CNC Sinker EDM prototypes for Bronze can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.

Does CNC Sinker EDM Bronze require dedicated tooling?

Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
