VT machining provides CNC Sinker EDM Molybdenum for customers who need accurate, repeatable Molybdenum components. Because Molybdenum is very high melting point and thermal stability, we adapt the process to suit — controlling the variables that matter for this alloy.
CNC Sinker EDM Capability for Molybdenum
- Blind cavities & ribs
- Fine surface (VDI grades)
- Tolerance to ±0.005 mm
- Hardened tool steel
How CNC Sinker EDM Molybdenum Works
Material is removed from the Molybdenum 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 Molybdenum
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened Molybdenum 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.
Working with Molybdenum
Molybdenum is very high melting point and thermal stability. 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 Molybdenum 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 Sinker EDM Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the Molybdenum 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 Molybdenum
Molybdenum 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 Molybdenum
Starting your project takes one email. Send your CAD or 2D drawing, the Molybdenum 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
Does CNC Sinker EDM Molybdenum require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
Can VT machining make custom Molybdenum parts to my drawing?
Yes. Molybdenum Molybdenum 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 surface finish is achievable on Molybdenum with CNC Sinker EDM?
Surface finish on Molybdenum is controlled to your specification; we confirm the achievable Ra against your callout.
How clean are the edges produced by CNC Sinker EDM on Molybdenum?
Machined Molybdenum edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
