What surface finish is achievable on Monel 400 with CNC Sinker EDM?
Surface finish on Monel 400 is controlled to your specification; we confirm the achievable Ra against your callout.
What is CNC Sinker EDM Monel 400 and how is it done?
CNC Sinker EDM Monel 400 refers to sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features. Applied to Monel 400 — strong and highly corrosion-resistant in marine/acid service — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Does CNC Sinker EDM Monel 400 require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
What tolerances can you hold for CNC Sinker EDM Monel 400?
Achievable tolerances for Monel 400 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.
