CNC EDM Drilling Titanium

CNC EDM Drilling Titanium from VT machining delivers precision Titanium 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 Titanium, which is high strength-to-weight, biocompatible, corrosion resistant.

How CNC EDM Drilling Titanium Works

Material is removed from the Titanium 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.

Standard is what a normal quotation assumes. Precision is available on nominated features and is priced separately, because it needs extra setups, in-process gauging and CMM verification. Call out only the features that need it — blanket-tightening a drawing is the single most common reason a quote comes back expensive.

Design Tips for CNC EDM Drilling Titanium

Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened Titanium 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 EDM Drilling Tolerances & Surface Finish

EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the Titanium 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 EDM Drilling Titanium

Titanium parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

What We Need to Quote CNC EDM Drilling Titanium

  • GeometrySTEP or IGES for the 3D model, plus a PDF drawing if you have tolerance callouts. A dimensioned sketch is enough to start.
  • MaterialThe exact Titanium grade and condition — temper, heat-treat state or hardness. If you are not sure, tell us the function and we will suggest one.
  • QuantityPrototype count and the expected annual volume. Both change how the part is made and therefore what it costs.
  • TolerancesWhich features are critical. Everything else runs to our standard tolerance, which is what keeps the price sensible.
  • FinishSurface treatment, cosmetic requirements, and any faces that must be masked.
  • DocumentsWhether you need a material certificate, dimensional report, FAIR or PPAP with the shipment.

Missing something from the list is not a problem — send what you have. We will come back with the specific questions rather than a generic form.

Frequently Asked Questions

Can you EDM-machine hardened Titanium?

Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult Titanium can be machined to fine detail and tight tolerance without distortion.

What is the typical lead time and minimum order for CNC EDM Drilling Titanium?

CNC EDM Drilling prototypes for Titanium 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 EDM Drilling Titanium parts?

CNC EDM Drilling Titanium parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Titanium components are required.

What tolerances can you hold for CNC EDM Drilling Titanium?

Achievable tolerances for Titanium 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.
