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 Swiss Machining
When turning Monel 400, machinability is moderate; work-hardens, steady feeds required. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for Monel 400 mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Swiss Machining Monel 400
| Feature | Standard | Precision |
|---|---|---|
| Outside diameter | ±0.05 mm | ±0.005 mm |
| Bore diameter | H9 | H6 |
| Length / shoulder position | ±0.10 mm | ±0.020 mm |
| Concentricity OD to ID | 0.05 mm TIR | 0.010 mm TIR |
| Roundness | 0.02 mm | 0.005 mm |
| Thread class | 6g / 2A | 4h / 3A |
| Surface finish, as turned | 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.
Design Tips for CNC Swiss Machining Monel 400
Small design adjustments often cut cost and lead time. Consistent diameters, standard thread forms and avoiding extremely long, slender features help Monel 400 turned parts stay concentric and economical. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Swiss Machining Tolerances & Surface Finish
Turned Monel 400 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.
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 Monel 400 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.
Why Monel 400?
Customers select Monel 400 for CNC Swiss Machining because it is strong and highly corrosion-resistant in marine/acid service. We handle grade verification and any required heat treatment or finishing.
CNC Swiss Machining 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.
Applications of CNC Swiss Machining Monel 400
Monel 400 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 Swiss Machining Monel 400
- 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 Monel 400 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.

Request a QuoteFrequently Asked Questions
Does CNC Swiss Machining Monel 400 require dedicated tooling?
Most Monel 400 turning work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What is the typical lead time and minimum order for CNC Swiss Machining Monel 400?
CNC Swiss Machining prototypes for Monel 400 can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
What tolerances can you hold for CNC Swiss Machining Monel 400?
Achievable tolerances for Monel 400 turning depend on the alloy, geometry and feature size. Turning holds diameter tolerances to around ±0.005 mm with concentricity within 0.01 mm. Exact figures are confirmed against your drawing callouts.
How clean are the edges produced by CNC Swiss Machining on Monel 400?
Machined Monel 400 edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
