Tool life is measured in minutes, not hours. Ceramic or coated-carbide tooling, low surface speed, high pressure coolant, and a scheduled tool change rather than waiting for failure.
Machining Incoloy 825 with CNC Wire EDM
When EDM machining Incoloy 825, machinability is very difficult; rigid setups, carbide/ceramic tooling, low speeds. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for Incoloy 825 mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Wire EDM Incoloy 825
| 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.
Secondary Operations & Finishing
Most Incoloy 825 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.
Why Incoloy 825?
Customers select Incoloy 825 for CNC Wire EDM because it is high-temperature strength and oxidation resistance. We handle grade verification and any required heat treatment or finishing.
CNC Wire EDM Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the Incoloy 825 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 Wire EDM 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 Wire EDM Incoloy 825
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened Incoloy 825 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.
Applications of CNC Wire EDM Incoloy 825
Incoloy 825 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 Wire EDM Incoloy 825
- 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 Incoloy 825 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.

Request a QuoteFrequently Asked Questions
Can you EDM-machine hardened Incoloy 825?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult Incoloy 825 can be machined to fine detail and tight tolerance without distortion.
How clean are the edges produced by CNC Wire EDM on Incoloy 825?
Machined Incoloy 825 edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What is CNC Wire EDM Incoloy 825 and how is it done?
CNC Wire EDM Incoloy 825 refers to wire EDM cuts conductive metal with a charged wire, achieving fine detail and tight tolerance with no cutting force. Applied to Incoloy 825 — high-temperature strength and oxidation resistance — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Why is Incoloy 825 a good choice for CNC Wire EDM?
Incoloy 825 is high-temperature strength and oxidation resistance, which makes it well suited to CNC Wire EDM. We tune the process to the alloy so the finished Incoloy 825 EDM machining part meets your dimensional and functional requirements.
