Why is 1144 Steel a good choice for CNC Sinker EDM?
1144 Steel is strong, economical and widely available, which makes it well suited to CNC Sinker EDM. We tune the process to the alloy so the finished 1144 Steel EDM machining part meets your dimensional and functional requirements.
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.
What is CNC Sinker EDM 1144 Steel and how is it done?
CNC Sinker EDM 1144 Steel refers to sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features. 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.
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.
