What tolerances can you hold for CNC Wire 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.
What is the typical lead time and minimum order for CNC Wire EDM Invar?
CNC Wire EDM prototypes for Invar can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
What surface finish is achievable on Invar with CNC Wire EDM?
Surface finish on Invar is controlled to your specification; we confirm the achievable Ra against your callout.
How clean are the edges produced by CNC Wire EDM on Invar?
Machined Invar edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
Does CNC Wire EDM Invar require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
