Published typical values for Inconel 718 (aged). Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.

Machining Incoloy 800 — what actually causes trouble

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 Turning

Incoloy 800 behaves predictably under CNC Turning 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.

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.

CNC Turning 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.

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.

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 Turning Tolerances & Surface Finish

Turned Incoloy 800 holds diameter tolerances to about ±0.005 mm with concentricity within 0.01 mm and good roundness. Turned finishes of Ra 0.4–0.8 µm are achievable with finishing passes and sharp tooling.

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.

Design Tips for CNC Turning Incoloy 800

We are happy to suggest design tweaks that improve manufacturability. Consistent diameters, standard thread forms and avoiding extremely long, slender features help Incoloy 800 turned parts stay concentric and economical. If you send your model early, we will return practical DFM feedback before you commit to production.

Applications of CNC Turning Incoloy 800

Customers order CNC Turning Incoloy 800 components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.

How to Order CNC Turning Incoloy 800

Getting a quote is simple. Share your model, the material grade, your quantity and target tolerances. You receive a clear quotation with lead time and honest manufacturability feedback.

What We Need to Quote CNC Turning 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.
