CNC Cylindrical Grinding Kovar from VT machining delivers precision Kovar parts produced to your exact drawing. Cylindrical grinding finishes outer diameters of rotational parts to precise size and roundness, and we tune every parameter to the behaviour of Kovar, which is matched thermal expansion for glass/ceramic seals.
CNC Cylindrical Grinding Capability for Kovar
- Roundness within 0.002 mm
- OD tolerance ±0.002 mm
- Ra to 0.2 µm
- Between-centers work
How CNC Cylindrical 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.
We start from your supplied geometry and tolerance scheme. The setup is designed to minimise re-clamping, which protects positional accuracy across features. A first article is verified against the drawing before the balance of the batch is released.
Working with Kovar
Kovar is matched thermal expansion for glass/ceramic seals. We translate those properties into a process plan: the right tooling, speeds, feeds and fixturing for the alloy.
Where the grade, temper or heat-treat condition matters to performance, we confirm it with you and can supply material certificates. Material is procured to recognised standards for consistent, repeatable results.
Secondary Operations & Finishing
Most Kovar parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
CNC Cylindrical Grinding Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
CNC Cylindrical 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.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Design Tips for CNC Cylindrical Grinding Kovar
Small design adjustments often cut cost and lead time. 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.

How clean are the edges produced by CNC Cylindrical Grinding on Kovar?
Machined Kovar edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
Why is Kovar a good choice for CNC Cylindrical Grinding?
Kovar is matched thermal expansion for glass/ceramic seals, which makes it well suited to CNC Cylindrical Grinding. We tune the process to the alloy so the finished Kovar grinding part meets your dimensional and functional requirements.
What tolerances can you hold for CNC Cylindrical 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.
Which industries use CNC Cylindrical Grinding Kovar parts?
CNC Cylindrical Grinding Kovar parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Kovar components are required.
