CNC Grinding Invar from VT machining delivers precision Invar parts produced to your exact drawing. CNC grinding removes material with a precision abrasive wheel to achieve tight dimensional tolerances and superior surface finish, and we tune every parameter to the behaviour of Invar, which is ultra-low thermal expansion.
CNC Grinding Capability for Invar
- Surface finish to Ra 0.1–0.4 µm
- Dimensional tolerance to ±0.002 mm
- Flatness/parallelism within 0.005 mm
- Wheel grit selected per alloy hardness
How CNC Grinding Invar Works
Our CNC Grinding setup for Invar starts from your CAD model. The program, tooling and parameters are selected from the part geometry and the known behaviour of Invar, then verified on the first article.
Applications of CNC Grinding Invar
Typical uses for CNC Grinding Invar include precision Invar components for electronics, instrumentation, automotive, medical and energy applications.
CNC Grinding Quality & Inspection
Each Invar part is inspected against your drawing, with critical dimensions verified before the batch is released. Documentation can be provided on request.
Why Invar for CNC Grinding
The reason customers specify Invar for CNC Grinding is straightforward — it is ultra-low thermal expansion. We handle the grade selection and any heat-treat or condition requirements with you.

What surface finish is achievable on Invar with CNC Grinding?
Grinding can take Invar to a fine finish — typically Ra 0.1–0.4 µm, and to a mirror grade on suitable alloys.
What tolerances can you hold for CNC Grinding Invar?
Achievable tolerances for Invar grinding depend on the alloy, geometry and feature size. Grinding routinely holds single-micron tolerances on diameter, flatness and parallelism. Exact figures are confirmed against your drawing callouts.
Can VT machining make custom Invar parts to my drawing?
Yes. Invar Invar grinding 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 is CNC Grinding Invar and how is it done?
CNC Grinding Invar refers to cNC grinding removes material with a precision abrasive wheel to achieve tight dimensional tolerances and superior surface finish. 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.
