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.
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 Inconel 718 with CNC Laser Cutting
The machinability of Inconel 718 is very difficult; rigid setups, carbide/ceramic tooling, low speeds. For CNC Laser Cutting we select tooling, feeds, speeds and coolant to match, keeping the Inconel 718 workpiece stable and the result accurate.
Because we machine Inconel 718 regularly, proven settings shorten setup and keep quality repeatable across reorders.
Achievable Tolerances for CNC Laser Cutting Inconel 718
| Feature | Standard | Precision |
|---|---|---|
| Contour dimension | ±0.10 mm | ±0.05 mm |
| Hole diameter | ±0.10 mm | ±0.05 mm |
| Kerf width | 0.20 mm | 0.10 mm |
| Squareness of cut edge | 0.5° | 0.2° |
| Heat-affected zone | 0.15 mm | 0.05 mm (N₂ assist) |
| Minimum hole diameter | 1.2 × thickness | 1.0 × thickness |
| Edge condition | light dross | burr-free, N₂ cut |
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 Laser Cutting Tolerances & Surface Finish
Laser-cut Inconel 718 holds contour tolerances around ±0.05 mm depending on thickness, with a narrow kerf and a clean, near burr-free edge.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
CNC Laser Cutting Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on Inconel 718 parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
Why Inconel 718?
Specifying Inconel 718 for CNC Laser Cutting Inconel 718 is usually about its properties: high-temperature strength and oxidation resistance. Tell us the condition you need and we machine to it.
Design Tips for CNC Laser Cutting Inconel 718
A few design choices make a real difference to cost and quality. Keeping holes no smaller than the material thickness, allowing for kerf, and grouping features sensibly improves edge quality and nesting yield on Inconel 718. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
We complete Inconel 718 components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
Applications of CNC Laser Cutting Inconel 718
CNC Laser Cutting of Inconel 718 supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.

What We Need to Quote CNC Laser Cutting Inconel 718
- 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 Inconel 718 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.
