Why is 1144 Steel a good choice for CNC Wire EDM?
1144 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 1144 Steel EDM machining part meets your dimensional and functional requirements.
What is the typical lead time and minimum order for CNC Wire EDM 1144 Steel?
CNC Wire EDM prototypes for 1144 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.
Can VT machining make custom 1144 Steel parts to my drawing?
Yes. 1144 Steel EDM machining is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
Can you EDM-machine hardened 1144 Steel?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult 1144 Steel can be machined to fine detail and tight tolerance without distortion.
What is CNC Wire EDM 1144 Steel and how is it done?
CNC Wire EDM 1144 Steel refers to wire EDM cuts conductive metal with a charged wire, achieving fine detail and tight tolerance with no cutting force. Applied to 1144 Steel — strong, economical and widely available — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What surface finish is achievable on 1144 Steel with CNC Wire EDM?
Surface finish on 1144 Steel is controlled to your specification; we confirm the achievable Ra against your callout.
