CNC Routing Invar from VT machining delivers precision Invar parts produced to your exact drawing. CNC routing cuts profiles and openings in sheet and plate at high feed rates with a rotating router bit, and we tune every parameter to the behaviour of Invar, which is ultra-low thermal expansion.
CNC Routing Capability for Invar
- High-feed profiling
- Sheet and plate stock
- Nested-part layouts
- Edge tolerance ±0.1 mm
How CNC Routing Invar Works
Rotating multi-flute cutters remove material as the Invar workpiece is driven through programmed tool paths on 3-, 4- or 5-axis machining centres. Climb milling, step-over and depth-of-cut are set so chip load stays in the ideal band for the alloy.
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.
Secondary Operations & Finishing
Finished Invar 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.
Design Tips for CNC Routing Invar
We are happy to suggest design tweaks that improve manufacturability. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in Invar. If you send your model early, we will return practical DFM feedback before you commit to production.
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.
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 Routing 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 Invar part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Working with Invar
As a material, Invar is ultra-low thermal expansion. 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.

What tolerances can you hold for CNC Routing Invar?
Achievable tolerances for Invar machining depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
Does CNC Routing Invar require dedicated tooling?
Most Invar machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Why is Invar a good choice for CNC Routing?
Invar is ultra-low thermal expansion, which makes it well suited to CNC Routing. We tune the process to the alloy so the finished Invar machining part meets your dimensional and functional requirements.
What is CNC Routing Invar and how is it done?
CNC Routing Invar refers to cNC routing cuts profiles and openings in sheet and plate at high feed rates with a rotating router bit. Applied to Invar — ultra-low thermal expansion — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Can VT machining make custom Invar parts to my drawing?
Yes. Invar Invar machining 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.
