CNC Punching Kovar is a core capability at VT machining. We combine controlled punching 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 Punching Capability for Kovar
- Sheet thickness 0.5–6 mm
- Hole position repeatability ±0.10 mm
- Punch/die clearance set per material
- Louver, emboss and tap-extrude tooling
How CNC Punching Kovar Works
For CNC Punching 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 Punching Quality & Inspection
Quality control for CNC Punching Kovar includes in-process checks and final inspection of the features you flag as critical, so the Kovar parts you receive are to print.
Why Kovar for CNC Punching
Kovar is selected for CNC Punching 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.

What material thickness or size range suits CNC Punching Kovar?
Punching suits Kovar sheet roughly 0.5–6 mm thick, with clearance matched to the gauge.
What tolerances can you hold for CNC Punching Kovar?
Achievable tolerances for Kovar punching depend on the alloy, geometry and feature size. Punching holds hole-position repeatability to around ±0.10 mm. Exact figures are confirmed against your drawing callouts.
What surface finish is achievable on Kovar with CNC Punching?
Surface finish on Kovar is controlled to your specification; we confirm the achievable Ra against your callout.
Does CNC Punching Kovar require dedicated tooling?
Punching uses programmable turret tooling; standard tools cover most patterns, with special tools added for unique forms.
What is CNC Punching Kovar and how is it done?
CNC Punching Kovar refers to cNC turret punching shears holes and form features in sheet metal using programmable tooling for fast, repeatable patterns. 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.
