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 Gear Cutting
The machinability of Inconel 718 is very difficult; rigid setups, carbide/ceramic tooling, low speeds. For CNC Gear 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.

| Profile deviation | 0.020 mm | 0.008 mm |
| Lead deviation | 0.020 mm | 0.008 mm |
| Pitch deviation (cumulative) | 0.040 mm | 0.015 mm |
| Runout | 0.030 mm | 0.010 mm |
| Tooth surface finish | Ra 1.6 µm | Ra 0.4 µm (ground) |
| Module range | m0.5–m8 | m1–m6 |
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 Gear Cutting Tolerances & Surface Finish
Gear features are produced to a specified DIN/AGMA accuracy class, with profile and lead controlled for quiet, durable running under load.
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.
Why Inconel 718?
Specifying Inconel 718 for CNC Gear 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.
CNC Gear 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.
Design Tips for CNC Gear Cutting Inconel 718
A few design choices make a real difference to cost and quality. Providing complete gear data (module, pressure angle, profile shift, quality class) lets us produce Inconel 718 gears right the first time. 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 Gear Cutting Inconel 718
CNC Gear 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 Gear 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.
