Can VT machining make custom Kovar parts to my drawing?
Yes. Kovar Kovar EDM 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 is CNC Sinker EDM Kovar and how is it done?
CNC Sinker EDM Kovar refers to sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features. 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.
What tolerances can you hold for CNC Sinker EDM Kovar?
Achievable tolerances for Kovar EDM machining depend on the alloy, geometry and feature size. EDM holds tolerances to around ±0.002 mm with no cutting force on the part. Exact figures are confirmed against your drawing callouts.
Does CNC Sinker EDM Kovar require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
What is the typical lead time and minimum order for CNC Sinker EDM Kovar?
CNC Sinker EDM 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.
