CNC Thread Grinding Quality & Inspection
We verify CNC Thread Grinding Invar dimensionally and, where required, provide inspection records — giving you confidence that every Invar part meets specification.
Why Invar for CNC Thread Grinding
Choosing Invar for CNC Thread Grinding Invar is usually about its properties: ultra-low thermal expansion. Tell us the grade and condition you need and we will machine to it.
How CNC Thread Grinding Invar Works
During grinding, the Invar workpiece is held and processed under CNC control so that feed, speed and the active parameters stay within the window that keeps the alloy stable and the result accurate.
Applications of CNC Thread Grinding Invar
CNC Thread Grinding Invar parts appear in aerospace, medical, automotive, electronics and industrial assemblies wherever accurate Invar components are required.

Why is Invar a good choice for CNC Thread Grinding?
Invar is ultra-low thermal expansion, which makes it well suited to CNC Thread Grinding. We tune the process to the alloy so the finished Invar grinding part meets your dimensional and functional requirements.
What surface finish is achievable on Invar with CNC Thread Grinding?
Grinding can take Invar to a fine finish — typically Ra 0.1–0.4 µm, and to a mirror grade on suitable alloys.
Which industries use CNC Thread Grinding Invar parts?
CNC Thread Grinding Invar parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Invar components are required.
What is CNC Thread Grinding Invar and how is it done?
CNC Thread Grinding Invar refers to thread grinding produces precise, high-finish threads on hardened parts and lead screws. 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.
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 tolerances can you hold for CNC Thread 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.
