VT machining provides CNC Wire EDM Steel for customers who need accurate, repeatable Steel components. Because Steel is strong, economical, widely available carbon/alloy grades, we adapt the process to suit — controlling the variables that matter for this alloy.
CNC Wire EDM Capability for Steel
- Kerf from 0.1 mm
- Tolerance to ±0.002 mm
- Hardened & exotic alloys
- Sharp internal corners
How CNC Wire EDM Steel Works
Material is removed from the 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.
CNC Wire EDM Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the 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 Steel
Steel is strong, economical, widely available carbon/alloy grades. 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.
Secondary Operations & Finishing
Most 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.
Design Tips for CNC Wire EDM Steel
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened 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.
CNC Wire EDM 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.
Applications of CNC Wire EDM Steel
Steel parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
How to Order CNC Wire EDM Steel
Starting your project takes one email. Send your CAD or 2D drawing, the Steel grade and condition, the quantity and any finish or inspection requirements. We respond quickly with price, lead time and any DFM notes, in clear English.

What is CNC Wire EDM Steel and how is it done?
CNC Wire EDM Steel refers to wire EDM cuts conductive metal with a charged wire, achieving fine detail and tight tolerance with no cutting force. Applied to Steel — strong, economical, widely available carbon/alloy grades — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What tolerances can you hold for CNC Wire EDM Steel?
Achievable tolerances for 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.
What is the typical lead time and minimum order for CNC Wire EDM Steel?
CNC Wire EDM prototypes for 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.
Which industries use CNC Wire EDM Steel parts?
CNC Wire EDM Steel parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Steel components are required.
