CNC Sinker EDM Steel from VT machining delivers precision Steel parts produced to your exact drawing. Sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features, and we tune every parameter to the behaviour of Steel, which is strong, economical, widely available carbon/alloy grades.
CNC Sinker EDM Capability for Steel
- Blind cavities & ribs
- Fine surface (VDI grades)
- Tolerance to ±0.005 mm
- Hardened tool steel
Why Steel for CNC Sinker EDM
Steel is selected for CNC Sinker EDM when a part needs the combination it offers — strong, economical, widely available carbon/alloy grades. We confirm the exact grade with you so the finished component performs as intended in service.
How CNC Sinker EDM Steel Works
For CNC Sinker EDM Steel, we plan the operation around the material: how Steel responds to heat, force and finishing dictates the wheel, tool, power or etchant we choose and the rate at which we run.
Applications of CNC Sinker EDM Steel
Customers order CNC Sinker EDM Steel for a wide range of Steel parts — from prototypes through to production volumes across multiple industries.
CNC Sinker EDM Quality & Inspection
Quality control for CNC Sinker EDM Steel includes in-process checks and final inspection of the features you flag as critical, so the Steel parts you receive are to print.

Request a QuoteFrequently Asked Questions
Does CNC Sinker EDM Steel 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 Steel parts to my drawing?
Yes. Steel Steel 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 tolerances can you hold for CNC Sinker EDM Steel?
Achievable tolerances for Steel 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.
What is CNC Sinker EDM Steel and how is it done?
CNC Sinker EDM Steel refers to sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features. Applied to Steel — strong, economical, widely available carbon/alloy grades — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Can you EDM-machine hardened Steel?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult Steel can be machined to fine detail and tight tolerance without distortion.
