Published typical values for Monel 400. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Work-hardens like stainless but tougher. If the drawing allows R-405, cycle time drops noticeably for the same corrosion performance.
Machining Monel 400 with CNC Routing
The machinability of Monel 400 is moderate; work-hardens, steady feeds required. For CNC Routing we select tooling, feeds, speeds and coolant to match, keeping the Monel 400 workpiece stable and the result accurate.
Because we machine Monel 400 regularly, proven settings shorten setup and keep quality repeatable across reorders.
Achievable Tolerances for CNC Routing Monel 400
| 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.
CNC Routing Tolerances & Surface Finish
For CNC Routing, 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.
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.

Design Tips for CNC Routing Monel 400
A few design choices make a real difference to cost and quality. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in Monel 400. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Routing Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on Monel 400 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.
