Request a QuoteFrequently Asked Questions
What tolerances can you hold for CNC Sinker EDM Invar?
Achievable tolerances for Invar 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 Invar?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult Invar can be machined to fine detail and tight tolerance without distortion.
What surface finish is achievable on Invar with CNC Sinker EDM?
Surface finish on Invar is controlled to your specification; we confirm the achievable Ra against your callout.
Why is Invar a good choice for CNC Sinker EDM?
Invar is ultra-low thermal expansion, which makes it well suited to CNC Sinker EDM. We tune the process to the alloy so the finished Invar EDM machining part meets your dimensional and functional requirements.
What is CNC Sinker EDM Invar and how is it done?
CNC Sinker EDM Invar refers to sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features. Applied to Invar — ultra-low thermal expansion — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
