Monel Material Data
| Density | 8.80 g/cm³ |
|---|---|
| Tensile strength | 550–690 MPa |
| Yield strength (0.2%) | 240–345 MPa |
| Hardness | 110–150 HB |
| Melting point | 1300–1350 °C |
| Thermal conductivity | 21.8 W/m·K |
| Thermal expansion | 13.9 ×10⁻⁶/K |
| Electrical conductivity | 3.4% |
| Machinability (C36000 = 100%) | 30% |
| Grades we run | Monel 400, Monel K-500, Monel R-405 (free-machining) |
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.
How CNC Gear Grinding Monel Works
Tooth profiles are generated in the Monel blank by a synchronised cutter, then refined to the required accuracy class. Module, pressure angle and helix are programmed from your gear data.
Programming is driven directly by your 3D model or print. Work-holding, tool selection and the cutting strategy are planned around the critical features and the material before the first chip is cut. First-off inspection confirms the process is centred before production continues.
Achievable Tolerances for CNC Gear Grinding Monel
| Feature | Standard | Precision |
|---|---|---|
| Accuracy class | DIN 8 / AGMA 10 | DIN 6 / AGMA 12 |
| 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 Grinding 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.
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.
CNC Gear Grinding 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 Monel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Design Tips for CNC Gear Grinding Monel
We are happy to suggest design tweaks that improve manufacturability. Providing complete gear data (module, pressure angle, profile shift, quality class) lets us produce Monel gears right the first time. If you send your model early, we will return practical DFM feedback before you commit to production.
Working with Monel
As a material, Monel is strong, highly corrosion resistant in marine/acid service. Our setup reflects the alloy's machinability so the finished part is accurate and free of avoidable defects.
We verify the exact grade and condition before machining, and traceable mill certs are available on request. We can work to your nominated material source or specification when required.
Secondary Operations & Finishing
Finished Monel 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.
Applications of CNC Gear Grinding Monel
Customers order CNC Gear Grinding Monel 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 Gear Grinding Monel
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 Gear Grinding Monel
- 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 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.
