CNC EDM Drilling Spring Steel from VT machining delivers precision Spring Steel parts produced to your exact drawing. Fast-hole EDM drilling produces small, deep holes in hard metals, including starter holes for wire EDM, and we tune every parameter to the behaviour of Spring Steel, which is high yield strength and elastic recovery.

How CNC EDM Drilling Spring Steel Works
Material is removed from the Spring Steel workpiece by controlled electrical discharges across a dielectric gap, with no mechanical contact. Flushing, on/off pulse timing and electrode/wire feed are set to balance speed against surface finish.
We start from your supplied geometry and tolerance scheme. The setup is designed to minimise re-clamping, which protects positional accuracy across features. A first article is verified against the drawing before the balance of the batch is released.
Design Tips for CNC EDM Drilling Spring Steel
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened Spring Steel that cannot be milled; allowing a small corner radius where possible speeds the cut. If you send your model early, we will return practical DFM feedback before you commit to production.
Secondary Operations & Finishing
Most Spring Steel parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
CNC EDM Drilling Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
CNC EDM Drilling Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the Spring Steel part, producing fine, controlled surface textures and sharp internal corners impossible to mill.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Working with Spring Steel
Spring Steel is high yield strength and elastic recovery. We translate those properties into a process plan: the right tooling, speeds, feeds and fixturing for the alloy.
Where the grade, temper or heat-treat condition matters to performance, we confirm it with you and can supply material certificates. Material is procured to recognised standards for consistent, repeatable results.
Applications of CNC EDM Drilling Spring Steel
Spring Steel parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

Request a QuoteFrequently Asked Questions
What tolerances can you hold for CNC EDM Drilling Spring Steel?
Achievable tolerances for Spring Steel 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.
Does CNC EDM Drilling Spring Steel require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
Why is Spring Steel a good choice for CNC EDM Drilling?
Spring Steel is high yield strength and elastic recovery, which makes it well suited to CNC EDM Drilling. We tune the process to the alloy so the finished Spring Steel EDM machining part meets your dimensional and functional requirements.
Can you EDM-machine hardened Spring Steel?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult Spring Steel can be machined to fine detail and tight tolerance without distortion.
