CNC Centerless Grinding Kovar is a core capability at VT machining. We combine controlled grinding with material-aware setup for Kovar — an alloy that is matched thermal expansion for glass/ceramic seals — to produce parts that meet your specification first time.
CNC Centerless Grinding Capability for Kovar
- No center holes needed
- High throughput
- Diameter ±0.003 mm
- Through-feed & in-feed
How CNC Centerless 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.
CNC Centerless 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.
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.
CNC Centerless 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.
Design Tips for CNC Centerless 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.
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.
Applications of CNC Centerless Grinding Kovar

Request a QuoteFrequently Asked Questions
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.
How clean are the edges produced by CNC Centerless Grinding on Kovar?
Machined Kovar edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
Does CNC Centerless Grinding Kovar require dedicated tooling?
Most Kovar grinding work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Why is Kovar a good choice for CNC Centerless Grinding?
Kovar is matched thermal expansion for glass/ceramic seals, which makes it well suited to CNC Centerless Grinding. We tune the process to the alloy so the finished Kovar grinding part meets your dimensional and functional requirements.
What surface finish is achievable on Kovar with CNC Centerless Grinding?
Grinding can take Kovar to a fine finish — typically Ra 0.1–0.4 µm, and to a mirror grade on suitable alloys.
