CNC Sinker EDM 20CrMnTi Steel from VT machining delivers precision 20CrMnTi Steel 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 20CrMnTi Steel, which is strong, economical and widely available.
CNC Sinker EDM Capability for 20CrMnTi Steel
- Carbon/low-alloy grades
- Economical & weldable
- Tolerance to ±0.02 mm
- Hardenable by heat treat
Machining 20CrMnTi Steel with CNC Sinker EDM
20CrMnTi Steel behaves predictably under CNC Sinker EDM once parameters are dialled in: machinability is good to excellent depending on carbon content; free-machining grades cut cleanly, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of 20CrMnTi Steel run consistently from one batch to the next.
Design Tips for CNC Sinker EDM 20CrMnTi Steel
We are happy to suggest design tweaks that improve manufacturability. EDM suits sharp internal corners, thin ribs and hardened 20CrMnTi 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 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 20CrMnTi Steel 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 20CrMnTi Steel 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 20CrMnTi Steel?
20CrMnTi Steel is chosen when a part needs what this grade offers — it is strong, economical and widely available. We confirm the grade and any temper or heat-treat condition with you before machining.
Secondary Operations & Finishing
Finished 20CrMnTi Steel 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 20CrMnTi Steel
Customers order CNC Sinker EDM 20CrMnTi Steel 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.

Request a QuoteFrequently Asked Questions
Does CNC Sinker EDM 20CrMnTi Steel require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
What is CNC Sinker EDM 20CrMnTi Steel and how is it done?
CNC Sinker EDM 20CrMnTi Steel refers to sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features. Applied to 20CrMnTi Steel — strong, economical and widely available — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Why is 20CrMnTi Steel a good choice for CNC Sinker EDM?
20CrMnTi Steel is strong, economical and widely available, which makes it well suited to CNC Sinker EDM. We tune the process to the alloy so the finished 20CrMnTi Steel EDM machining part meets your dimensional and functional requirements.
How clean are the edges produced by CNC Sinker EDM on 20CrMnTi Steel?
Machined 20CrMnTi Steel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What material thickness or size range suits CNC Sinker EDM 20CrMnTi Steel?
We machine 20CrMnTi Steel across a broad size range; share your part envelope for confirmation.
