What surface finish is achievable on 12L14 Steel with CNC Wire EDM?
Surface finish on 12L14 Steel is controlled to your specification; we confirm the achievable Ra against your callout.
Can you EDM-machine hardened 12L14 Steel?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult 12L14 Steel can be machined to fine detail and tight tolerance without distortion.
What is the typical lead time and minimum order for CNC Wire EDM 12L14 Steel?
CNC Wire EDM prototypes for 12L14 Steel can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
Why is 12L14 Steel a good choice for CNC Wire EDM?
12L14 Steel is strong, economical and widely available, which makes it well suited to CNC Wire EDM. We tune the process to the alloy so the finished 12L14 Steel EDM machining part meets your dimensional and functional requirements.
