Does CNC EDM Drilling Incoloy 825 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 EDM Drilling Incoloy 825 and how is it done?
CNC EDM Drilling Incoloy 825 refers to fast-hole EDM drilling produces small, deep holes in hard metals, including starter holes for wire EDM. Applied to Incoloy 825 — high-temperature strength and oxidation resistance — 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 EDM Drilling Incoloy 825?
Achievable tolerances for Incoloy 825 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.
Can you EDM-machine hardened Incoloy 825?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult Incoloy 825 can be machined to fine detail and tight tolerance without distortion.
What surface finish is achievable on Incoloy 825 with CNC EDM Drilling?
Surface finish on Incoloy 825 is controlled to your specification; we confirm the achievable Ra against your callout.
What is the typical lead time and minimum order for CNC EDM Drilling Incoloy 825?
CNC EDM Drilling prototypes for Incoloy 825 can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
