CNC Turning Kovar is a core capability at VT machining. We combine controlled turning 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 Turning Capability for Kovar
- Diameter tolerance to ±0.005 mm
- Concentricity within 0.01 mm
- OD/ID, threading, grooving
- Bar and chuck work
Why Kovar for CNC Turning
Kovar is selected for CNC Turning when a part needs the combination it offers — matched thermal expansion for glass/ceramic seals. We confirm the exact grade with you so the finished component performs as intended in service.
How CNC Turning Kovar Works
For CNC Turning Kovar, we plan the operation around the material: how Kovar responds to heat, force and finishing dictates the wheel, tool, power or etchant we choose and the rate at which we run.
CNC Turning Quality & Inspection
Quality control for CNC Turning Kovar includes in-process checks and final inspection of the features you flag as critical, so the Kovar parts you receive are to print.

What is CNC Turning Kovar and how is it done?
CNC Turning Kovar refers to cNC turning rotates the workpiece against a single-point tool to produce cylindrical features, threads and grooves. 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.
Can VT machining make custom Kovar parts to my drawing?
Yes. Kovar Kovar turning 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 Turning Kovar?
Achievable tolerances for Kovar turning depend on the alloy, geometry and feature size. Turning holds diameter tolerances to around ±0.005 mm with concentricity within 0.01 mm. Exact figures are confirmed against your drawing callouts.
Does CNC Turning Kovar require dedicated tooling?
Most Kovar turning work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What surface finish is achievable on Kovar with CNC Turning?
Surface finish on Kovar is controlled to your specification; we confirm the achievable Ra against your callout.
