VT machining provides CNC Saw Cutting Invar for customers who need accurate, repeatable Invar components. Because Invar is ultra-low thermal expansion, we adapt the process to suit — controlling the variables that matter for this alloy.
CNC Saw Cutting Capability for Invar
- Length tolerance ±0.2 mm
- Bar, tube & plate
- Bundle cutting
- Square-cut faces
How CNC Saw Cutting Invar Works
The Invar blank is bent or formed against tooling under CNC-controlled ram travel and back-gauge positioning. Bend allowance and springback are compensated in the program so finished angles hit the print.
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.
Design Tips for CNC Saw Cutting Invar
We are happy to suggest design tweaks that improve manufacturability. Consistent bend radii, adequate flange lengths and grain-direction awareness reduce cracking and springback in formed Invar. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Saw Cutting Tolerances & Surface Finish
Formed Invar holds bend angles to about ±0.5° and consistent flange dimensions, with bend allowance compensated for the material and thickness.
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 Saw Cutting 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.
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.
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.
Applications of CNC Saw Cutting Invar
Customers order CNC Saw Cutting Invar 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.

What material thickness or size range suits CNC Saw Cutting Invar?
We form Invar sheet and plate to your developed flat pattern and bend sequence.
Can VT machining make custom Invar parts to my drawing?
Yes. Invar Invar forming 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.
Does CNC Saw Cutting Invar require dedicated tooling?
Most Invar forming work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
How clean are the edges produced by CNC Saw Cutting on Invar?
Machined Invar edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What surface finish is achievable on Invar with CNC Saw Cutting?
Surface finish on Invar is controlled to your specification; we confirm the achievable Ra against your callout.
