VT machining provides CNC Sinker EDM Nickel for customers who need accurate, repeatable Nickel components. Because Nickel is corrosion and heat resistant, we adapt the process to suit — controlling the variables that matter for this alloy.
CNC Sinker EDM Capability for Nickel
- Blind cavities & ribs
- Fine surface (VDI grades)
- Tolerance to ±0.005 mm
- Hardened tool steel
How CNC Sinker EDM Nickel Works
Material is removed from the Nickel 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 Sinker 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.
Design Tips for CNC Sinker EDM Nickel
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened Nickel 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 Nickel 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.
Working with Nickel
Nickel is corrosion and heat resistant. 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.
CNC Sinker EDM Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the Nickel 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.
Applications of CNC Sinker EDM Nickel
Nickel 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 Sinker EDM Nickel
Starting your project takes one email. Send your CAD or 2D drawing, the Nickel 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.

Request a QuoteFrequently Asked Questions
How clean are the edges produced by CNC Sinker EDM on Nickel?
Machined Nickel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What tolerances can you hold for CNC Sinker EDM Nickel?
Achievable tolerances for Nickel 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.
Can you EDM-machine hardened Nickel?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult Nickel can be machined to fine detail and tight tolerance without distortion.
What surface finish is achievable on Nickel with CNC Sinker EDM?
Surface finish on Nickel is controlled to your specification; we confirm the achievable Ra against your callout.
