CNC Sinker EDM C110 Copper from VT machining delivers precision C110 Copper parts made to your exact drawing. Sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features, with parameters tuned to C110 Copper, which is excellent electrical and thermal conductivity.

Published typical values for C11000 ETP. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
It smears rather than cuts. Razor-sharp uncoated tooling and high rake; if the print allows it, C14500 tellurium copper machines four times better at ~90% IACS.
Machining C110 Copper with CNC Sinker EDM
C110 Copper behaves predictably under CNC Sinker EDM once parameters are dialled in: machinability is moderate; gummy, so sharp tooling and coolant are used, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of C110 Copper run consistently from one batch to the next.
Achievable Tolerances for CNC Sinker EDM C110 Copper
| Feature | Standard | Precision |
|---|---|---|
| Profile dimension | ±0.010 mm | ±0.002 mm |
| Internal corner radius | 0.15 mm | 0.05 mm |
| Taper control over 50 mm | 0.02 mm | 0.005 mm |
| Surface finish (skim passes) | Ra 0.8 µm | Ra 0.2 µm |
| Recast layer | 10 µm | 2 µm (fine skim) |
| Start-hole diameter | 1.0 mm | 0.25 mm |
| Workpiece hardness | no limit (conductive) | no limit (conductive) |
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.
CNC Sinker EDM Quality & Inspection
We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every C110 Copper part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
CNC Sinker EDM Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the C110 Copper part, producing fine, controlled surface textures and sharp internal corners impossible to mill.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
Why C110 Copper?
C110 Copper is chosen when a part needs what this grade offers — it is excellent electrical and thermal conductivity. We confirm the grade and any temper or heat-treat condition with you before machining.
Design Tips for CNC Sinker EDM C110 Copper
We are happy to suggest design tweaks that improve manufacturability. EDM suits sharp internal corners, thin ribs and hardened C110 Copper 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
Finished C110 Copper parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.
Applications of CNC Sinker EDM C110 Copper
Customers order CNC Sinker EDM C110 Copper components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.
How to Order CNC Sinker EDM C110 Copper
Getting a quote is simple. Share your model, the material grade, your quantity and target tolerances. You receive a clear quotation with lead time and honest manufacturability feedback.
Finishing Options for C110 Copper
| Finish | Thickness / effect | Why it gets specified |
|---|---|---|
| Tin plate | 3–15 µm | Solderable, prevents oxidation |
| Silver plate | 2–10 µm | Lowest contact resistance for RF and power |
| Nickel underplate | 2–5 µm | Diffusion barrier under tin or gold |
| Gold flash | 0.05–1 µm | Contact surfaces, over nickel |
| Deburr / edge break | 0.05–0.3 mm | All parts unless the drawing says otherwise |
| Bead blast | Ra 1.6–3.2 µm | Uniform matt finish, hides tool marks |
| Laser marking | — | Part number, lot code, data matrix |

What We Need to Quote CNC Sinker EDM C110 Copper
- 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 C110 Copper 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.

What is CNC Sinker EDM C110 Copper and how is it done?
CNC Sinker EDM C110 Copper refers to sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features. Applied to C110 Copper — excellent electrical and thermal conductivity — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Can you EDM-machine hardened C110 Copper?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult C110 Copper can be machined to fine detail and tight tolerance without distortion.
