What is the typical lead time and minimum order for CNC Sinker EDM Grade 7 Titanium?
CNC Sinker EDM prototypes for Grade 7 Titanium can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
Can VT machining make custom Grade 7 Titanium parts to my drawing?
Yes. Grade 7 Titanium 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.
Can you EDM-machine hardened Grade 7 Titanium?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult Grade 7 Titanium can be machined to fine detail and tight tolerance without distortion.
Does CNC Sinker EDM Grade 7 Titanium require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
