What surface finish is achievable on Ti-6Al-4V Titanium with CNC Sinker EDM?
Surface finish on Ti-6Al-4V Titanium is controlled to your specification; we confirm the achievable Ra against your callout.
What tolerances can you hold for CNC Sinker EDM Ti-6Al-4V Titanium?
Achievable tolerances for Ti-6Al-4V Titanium 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 Ti-6Al-4V Titanium require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
What is CNC Sinker EDM Ti-6Al-4V Titanium and how is it done?
CNC Sinker EDM Ti-6Al-4V Titanium refers to sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features. Applied to Ti-6Al-4V Titanium — high strength-to-weight, biocompatible and corrosion resistant — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Can you EDM-machine hardened Ti-6Al-4V Titanium?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult Ti-6Al-4V Titanium can be machined to fine detail and tight tolerance without distortion.
