VT machining provides CNC Reaming Incoloy 800 for customers who need accurate, repeatable Incoloy 800 components. The machinability of Incoloy 800 is very difficult; rigid setups, carbide/ceramic tooling, low speeds, so we set the operation up specifically for this grade.

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 Reaming
When machining Incoloy 800, 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 800 mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Reaming 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 |
| Flatness over 100 mm | 0.05 mm | 0.015 mm |
| Perpendicularity | 0.10 mm | 0.020 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.
Why Incoloy 800?
Customers select Incoloy 800 for CNC Reaming because it is high-temperature strength and oxidation resistance. We handle grade verification and any required heat treatment or finishing.
Design Tips for CNC Reaming Incoloy 800
Small design adjustments often cut cost and lead time. 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.
CNC Reaming 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.
CNC Reaming Tolerances & Surface Finish
For CNC Reaming, 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.
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.
Secondary Operations & Finishing
Most Incoloy 800 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 Reaming Incoloy 800
Incoloy 800 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 Reaming 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.
