CNC Milling Kovar from VT machining delivers precision Kovar parts produced to your exact drawing. Multi-axis milling cutters remove material to produce prismatic features, pockets, slots and contoured 3D surfaces, and we tune every parameter to the behaviour of Kovar, which is matched thermal expansion for glass/ceramic seals.
CNC Milling Capability for Kovar
- 3-, 4- and 5-axis capability
- Tolerance to ±0.01 mm
- Pocket/slot/contour features
- Spindle speeds to 12,000+ rpm
Why Kovar for CNC Milling
Kovar is selected for CNC Milling 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.
Applications of CNC Milling Kovar
Customers order CNC Milling Kovar for a wide range of Kovar parts — from prototypes through to production volumes across multiple industries.
How CNC Milling Kovar Works
For CNC Milling 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 Milling Quality & Inspection
Quality control for CNC Milling Kovar includes in-process checks and final inspection of the features you flag as critical, so the Kovar parts you receive are to print.

Request a QuoteFrequently Asked Questions
Can VT machining make custom Kovar parts to my drawing?
Yes. Kovar Kovar machining 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 Milling Kovar?
Achievable tolerances for Kovar machining depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
Does CNC Milling Kovar require dedicated tooling?
Most Kovar machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What is the typical lead time and minimum order for CNC Milling Kovar?
CNC Milling prototypes for Kovar can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
Why is Kovar a good choice for CNC Milling?
Kovar is matched thermal expansion for glass/ceramic seals, which makes it well suited to CNC Milling. We tune the process to the alloy so the finished Kovar machining part meets your dimensional and functional requirements.
