CNC Plasma Cutting Invar is a core capability at VT machining. We combine controlled cutting with material-aware setup for Invar — an alloy that is ultra-low thermal expansion — to produce parts that meet your specification first time.
CNC Plasma Cutting Capability for Invar
- Plate to 30+ mm
- High cutting speed
- Conductive metals
- Bevel-cut capable
How CNC Plasma 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.
Working with Invar
Invar is ultra-low thermal expansion. We translate those properties into a process plan: the right tooling, speeds, feeds and fixturing for the alloy.
Where the grade, temper or heat-treat condition matters to performance, we confirm it with you and can supply material certificates. Material is procured to recognised standards for consistent, repeatable results.
CNC Plasma 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.
Secondary Operations & Finishing
Most Invar 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.
Design Tips for CNC Plasma 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 Plasma Cutting 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 Plasma 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.
How to Order CNC Plasma Cutting Invar
Starting your project takes one email. Send your CAD or 2D drawing, the Invar grade and condition, the quantity and any finish or inspection requirements. We respond quickly with price, lead time and any DFM notes, in clear English.

Request a QuoteFrequently Asked Questions
What material thickness or size range suits CNC Plasma Cutting Invar?
Laser-cut Invar thickness depends on the alloy and its reflectivity; we tune the fiber source and assist gas accordingly.
Which industries use CNC Plasma Cutting Invar parts?
CNC Plasma Cutting Invar parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Invar components are required.
Does CNC Plasma Cutting Invar require dedicated tooling?
Most Invar cutting 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 Plasma Cutting on Invar?
Laser cutting leaves Invar with a narrow kerf and a clean, near burr-free edge and only a small heat-affected zone.
