CNC Sinker EDM Brass

CNC Sinker EDM Brass from VT machining delivers precision Brass 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 Brass, which is free-machining, good conductivity, attractive finish.

CNC Sinker EDM Capability for Brass

• Blind cavities & ribs
• Fine surface (VDI grades)
• Tolerance to ±0.005 mm
• Hardened tool steel

How CNC Sinker EDM Brass Works

Material is removed from the Brass 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.

Every job begins from your CAD model or 2D drawing. Fixturing and tool paths are planned so the most critical dimensions are produced in the most rigid, repeatable setup. Critical dimensions are checked on the first part and monitored through the run.

Secondary Operations & Finishing

We complete Brass components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.

CNC Sinker EDM Quality & Inspection

Consistent quality comes from disciplined process control. Critical dimensions on Brass parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.

CNC Sinker EDM Tolerances & Surface Finish

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

Design Tips for CNC Sinker EDM Brass

A few design choices make a real difference to cost and quality. EDM suits sharp internal corners, thin ribs and hardened Brass 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 Brass

Brass offers a useful combination of properties: it is free-machining, good conductivity, attractive finish. Those characteristics shape how we approach EDM — from tool and parameter selection to work-holding and coolant.

If your application is sensitive to alloy condition, we agree the specification in writing and document it. Stock is sourced from reputable suppliers so what you order is what you receive.

Applications of CNC Sinker EDM Brass

CNC Sinker EDM of Brass supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.
