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