Published typical values for C93200 (SAE 660). Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Cast bearing bronze has porosity. On sealing faces we specify continuous-cast stock rather than sand-cast, because a pinhole in a bore face is not repairable.
Machining C630 Aluminum Bronze with CNC EDM Drilling
When EDM machining C630 Aluminum Bronze, machinability is moderate; tough, strong, corrosion-resistant. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for C630 Aluminum Bronze mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC EDM Drilling C630 Aluminum Bronze
| Feature | Standard | Precision |
|---|---|---|
| Profile dimension | ±0.010 mm | ±0.002 mm |
| Internal corner radius | 0.15 mm | 0.05 mm |
| Taper control over 50 mm | 0.02 mm | 0.005 mm |
| Surface finish (skim passes) | Ra 0.8 µm | Ra 0.2 µm |
| Recast layer | 10 µm | 2 µm (fine skim) |
| Start-hole diameter | 1.0 mm | 0.25 mm |
| Workpiece hardness | no limit (conductive) | no limit (conductive) |
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.
Why C630 Aluminum Bronze?
Customers select C630 Aluminum Bronze for CNC EDM Drilling because it is high-strength and seawater-corrosion-resistant. We handle grade verification and any required heat treatment or finishing.
CNC EDM Drilling Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the C630 Aluminum 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 EDM Drilling Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
Design Tips for CNC EDM Drilling C630 Aluminum Bronze
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened C630 Aluminum 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
Most C630 Aluminum Bronze parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
Applications of CNC EDM Drilling C630 Aluminum Bronze
C630 Aluminum Bronze parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

What We Need to Quote CNC EDM Drilling C630 Aluminum Bronze
- 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 C630 Aluminum Bronze 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.

What tolerances can you hold for CNC EDM Drilling C630 Aluminum Bronze?
Achievable tolerances for C630 Aluminum 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 CNC EDM Drilling C630 Aluminum Bronze and how is it done?
CNC EDM Drilling C630 Aluminum Bronze refers to fast-hole EDM drilling produces small, deep holes in hard metals, including starter holes for wire EDM. Applied to C630 Aluminum Bronze — high-strength and seawater-corrosion-resistant — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Can VT machining make custom C630 Aluminum Bronze parts to my drawing?
Yes. C630 Aluminum Bronze C630 Aluminum Bronze EDM machining is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
Can you EDM-machine hardened C630 Aluminum Bronze?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult C630 Aluminum Bronze can be machined to fine detail and tight tolerance without distortion.
