VT machining provides CNC Thread Grinding Kovar for customers who need accurate, repeatable Kovar components. Because Kovar is matched thermal expansion for glass/ceramic seals, we adapt the process to suit — controlling the variables that matter for this alloy.
CNC Thread Grinding Capability for Kovar
- Pitch accuracy to grade 3
- Hardened-part threading
- Lead screws & gauges
- Fine surface finish
How CNC Thread Grinding Kovar Works
An abrasive wheel removes a fine, controlled layer from the Kovar part. Wheel specification, dressing interval, infeed and coolant are matched to the alloy's hardness so the surface is not burned or left with residual stress.
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.
Design Tips for CNC Thread Grinding Kovar
We are happy to suggest design tweaks that improve manufacturability. Allowing adequate grind stock, specifying realistic flatness over the true datum, and relieving corners help us hit tight tolerances on Kovar efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Thread Grinding 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 Kovar part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Working with Kovar
As a material, Kovar is matched thermal expansion for glass/ceramic seals. 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.
Secondary Operations & Finishing
Finished Kovar 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.
CNC Thread Grinding Tolerances & Surface Finish
Ground Kovar reaches single-micron tolerances on size, flatness and parallelism, with surface finishes down to Ra 0.1–0.4 µm — and a near-mirror finish on suitable alloys.
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.
Applications of CNC Thread Grinding Kovar
Customers order CNC Thread Grinding Kovar components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.

Why is Kovar a good choice for CNC Thread Grinding?
Kovar is matched thermal expansion for glass/ceramic seals, which makes it well suited to CNC Thread Grinding. We tune the process to the alloy so the finished Kovar grinding part meets your dimensional and functional requirements.
Can VT machining make custom Kovar parts to my drawing?
Yes. Kovar Kovar 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 Thread Grinding Kovar and how is it done?
CNC Thread Grinding Kovar refers to thread grinding produces precise, high-finish threads on hardened parts and lead screws. Applied to Kovar — matched thermal expansion for glass/ceramic seals — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What surface finish is achievable on Kovar with CNC Thread Grinding?
Grinding can take Kovar 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 Thread Grinding Kovar?
Achievable tolerances for Kovar 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.
