How CNC Waterjet Cutting Invar Works
A focused fibre-laser beam melts and blows material from the Invar sheet along the programmed contour. Power, focal position, nozzle stand-off and assist-gas pressure are tuned to the alloy and thickness for a clean, square edge.
We start from your supplied geometry and tolerance scheme. The setup is designed to minimise re-clamping, which protects positional accuracy across features. A first article is verified against the drawing before the balance of the batch is released.
Achievable Tolerances for CNC Waterjet Cutting Invar
| 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.
Design Tips for CNC Waterjet Cutting Invar
Small design adjustments often cut cost and lead time. Keeping holes no smaller than the material thickness, allowing for kerf, and grouping features sensibly improves edge quality and nesting yield on Invar. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Waterjet Cutting Tolerances & Surface Finish
Laser-cut Invar 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.
Applications of CNC Waterjet Cutting Invar
Invar parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
Typical Invar Parts for CNC Waterjet Cutting
Illustrative examples of CNC Waterjet Cutting Invar parts and the callouts that usually drive the process plan. They show the kind of work that fits this process; they are not specific customer orders.
Control panel face
- Material
- Invar
- Size
- 400 × 300 × 1.5 mm
- Key callouts
- Cutout position ±0.10 mm, no dross on visible face
- Batch
- 600 pcs
Cut with nitrogen so the edge takes powder coat without secondary grinding.

- Size
- 250 × 120 × 4 mm
- Key callouts
- Contour ±0.10 mm, bend-relief notches
- Batch

What We Need to Quote CNC Waterjet Cutting Invar
- 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 Invar 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
Which industries use CNC Waterjet Cutting Invar parts?
CNC Waterjet Cutting Invar parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Invar components are required.
Why is Invar a good choice for CNC Waterjet Cutting?
Invar is ultra-low thermal expansion, which makes it well suited to CNC Waterjet Cutting. We tune the process to the alloy so the finished Invar cutting part meets your dimensional and functional requirements.
What tolerances can you hold for CNC Waterjet Cutting Invar?
Achievable tolerances for Invar cutting depend on the alloy, geometry and feature size. Laser cutting holds contour tolerances to around ±0.05 mm depending on thickness. Exact figures are confirmed against your drawing callouts.
Can VT machining make custom Invar parts to my drawing?
Yes. Invar cutting is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
