CNC Laser 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 Laser Cutting Capability for Invar
- Fiber 1–6 kW
- Kerf 0.1–0.3 mm
- Contour ±0.05 mm
- N₂/O₂ assist gas
How CNC Laser 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.
Every job begins from your CAD model or 2D drawing. Fixturing and tool paths are planned so the most critical dimensions are produced in the most rigid, repeatable setup. Critical dimensions are checked on the first part and monitored through the run.
Working with Invar
Invar offers a useful combination of properties: it is ultra-low thermal expansion. Those characteristics shape how we approach laser cutting — from tool and parameter selection to work-holding and coolant.
If your application is sensitive to alloy condition, we agree the specification in writing and document it. Stock is sourced from reputable suppliers so what you order is what you receive.
Design Tips for CNC Laser Cutting Invar
A few design choices make a real difference to cost and quality. 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 Laser 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.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
CNC Laser Cutting Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on Invar parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
Secondary Operations & Finishing
We complete Invar components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
Applications of CNC Laser Cutting Invar
CNC Laser Cutting of Invar supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.

Request a QuoteFrequently Asked Questions
How clean are the edges produced by CNC Laser 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.
What tolerances can you hold for CNC Laser 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.
What material thickness or size range suits CNC Laser Cutting Invar?
Laser-cut Invar thickness depends on the alloy and its reflectivity; we tune the fiber source and assist gas accordingly.
Can VT machining make custom Invar parts to my drawing?
Yes. Invar 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.
Why is Invar a good choice for CNC Laser Cutting?
Invar is ultra-low thermal expansion, which makes it well suited to CNC Laser Cutting. We tune the process to the alloy so the finished Invar cutting part meets your dimensional and functional requirements.
Which industries use CNC Laser Cutting Invar parts?
CNC Laser Cutting Invar parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Invar components are required.
