CNC Lathe Machining Invar from VT machining delivers precision Invar parts produced to your exact drawing. CNC lathe machining produces precision rotational parts with combined turning, facing, drilling and threading, and we tune every parameter to the behaviour of Invar, which is ultra-low thermal expansion.
CNC Lathe Machining Capability for Invar
- Live-tool capability
- Sub-spindle pickup
- OD/ID + cross features
- Diameter tolerance ±0.005 mm
How CNC Lathe Machining Invar Works
The Invar bar or billet rotates in the spindle while single-point tools shape outer diameters, bores, faces, grooves and threads. Constant surface speed control keeps cutting conditions stable from large to small diameters.
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.
CNC Lathe Machining Tolerances & Surface Finish
Turned Invar holds diameter tolerances to about ±0.005 mm with concentricity within 0.01 mm and good roundness. Turned finishes of Ra 0.4–0.8 µm are achievable with finishing passes and sharp tooling.
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.
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.
CNC Lathe Machining 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.
Design Tips for CNC Lathe Machining Invar
We are happy to suggest design tweaks that improve manufacturability. Consistent diameters, standard thread forms and avoiding extremely long, slender features help Invar turned parts stay concentric and economical. If you send your model early, we will return practical DFM feedback before you commit to production.

Why is Invar a good choice for CNC Lathe Machining?
Invar is ultra-low thermal expansion, which makes it well suited to CNC Lathe Machining. We tune the process to the alloy so the finished Invar turning part meets your dimensional and functional requirements.
What surface finish is achievable on Invar with CNC Lathe Machining?
Surface finish on Invar is controlled to your specification; we confirm the achievable Ra against your callout.
What tolerances can you hold for CNC Lathe Machining Invar?
Achievable tolerances for Invar turning depend on the alloy, geometry and feature size. Turning holds diameter tolerances to around ±0.005 mm with concentricity within 0.01 mm. Exact figures are confirmed against your drawing callouts.
Can VT machining make custom Invar parts to my drawing?
Yes. Invar Invar turning 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.
What material thickness or size range suits CNC Lathe Machining Invar?
Turned Invar parts are produced from bar or chuck stock across a wide diameter range.
