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 800 with CNC Precision Machining
Incoloy 800 behaves predictably under CNC Precision Machining once parameters are dialled in: machinability is very difficult; rigid setups, carbide/ceramic tooling, low speeds, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of Incoloy 800 run consistently from one batch to the next.
Achievable Tolerances for CNC Precision Machining Incoloy 800
| Feature | Standard | Precision |
|---|---|---|
| Linear dimension (< 100 mm) | ±0.05 mm | ±0.010 mm |
| Linear dimension (100–300 mm) | ±0.10 mm | ±0.025 mm |
| Hole diameter (reamed) | H9 | H7 |
| True position of hole pattern | ±0.10 mm | ±0.025 mm |

| Surface finish, as machined | Ra 1.6 µm | Ra 0.4 µm |
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
Finished Incoloy 800 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 Precision Machining 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 Incoloy 800 part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Design Tips for CNC Precision Machining Incoloy 800
We are happy to suggest design tweaks that improve manufacturability. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in Incoloy 800. If you send your model early, we will return practical DFM feedback before you commit to production.
Why Incoloy 800?
Incoloy 800 is chosen when a part needs what this grade offers — it is high-temperature strength and oxidation resistance. We confirm the grade and any temper or heat-treat condition with you before machining.
CNC Precision Machining Tolerances & Surface Finish
For CNC Precision Machining, dimensional and positional tolerances around ±0.01 mm are routine, tightening toward ±0.005 mm on precision setups. Surface finish on machined faces typically falls in the Ra 0.4–1.6 µm range depending on tooling and pass strategy.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.

What We Need to Quote CNC Precision Machining Incoloy 800
- 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 800 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.
