VT machining provides CNC 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 Grinding Capability for Kovar
- Surface finish to Ra 0.1–0.4 µm
- Dimensional tolerance to ±0.002 mm
- Flatness/parallelism within 0.005 mm
- Wheel grit selected per alloy hardness
How CNC 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.
Every job begins from your CAD model or 2D drawing. Fixturing and tool paths are planned so the most critical dimensions are produced in the most rigid, repeatable setup. Critical dimensions are checked on the first part and monitored through the run.
CNC 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.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
Secondary Operations & Finishing
We complete Kovar components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
Working with Kovar
Kovar offers a useful combination of properties: it is matched thermal expansion for glass/ceramic seals. Those characteristics shape how we approach grinding — from tool and parameter selection to work-holding and coolant.
If your application is sensitive to alloy condition, we agree the specification in writing and document it. Stock is sourced from reputable suppliers so what you order is what you receive.
CNC Grinding Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on Kovar parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
Design Tips for CNC Grinding Kovar
A few design choices make a real difference to cost and quality. 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.
