Request a QuoteFrequently Asked Questions
What tolerances can you hold for CNC Surface 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.
What surface finish is achievable on Invar with CNC Surface Grinding?
Grinding can take Invar to a fine finish — typically Ra 0.1–0.4 µm, and to a mirror grade on suitable alloys.
Why is Invar a good choice for CNC Surface Grinding?
Invar is ultra-low thermal expansion, which makes it well suited to CNC Surface Grinding. We tune the process to the alloy so the finished Invar grinding part meets your dimensional and functional requirements.
What is the typical lead time and minimum order for CNC Surface Grinding Invar?
CNC Surface Grinding prototypes for Invar can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
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.
