Does CNC Sinker EDM Hastelloy C22 require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
Which industries use CNC Sinker EDM Hastelloy C22 parts?
CNC Sinker EDM Hastelloy C22 parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Hastelloy C22 components are required.
What is CNC Sinker EDM Hastelloy C22 and how is it done?
CNC Sinker EDM Hastelloy C22 refers to sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features. Applied to Hastelloy C22 — 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 Sinker EDM Hastelloy C22?
Achievable tolerances for Hastelloy C22 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.
