CNC EDM Drilling Brass

CNC EDM Drilling Brass is a core capability at VT machining. We combine controlled EDM machining with material-aware setup for Brass — an alloy that is free-machining, good conductivity, attractive finish — to produce parts that meet your specification first time.

CNC EDM Drilling Capability for Brass

• Ø0.2–3 mm holes
• Deep aspect ratios
• Hardened-metal drilling
• Angled hole capability

How CNC EDM Drilling 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.

CNC EDM Drilling 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 EDM Drilling 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 EDM Drilling 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.

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.

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 EDM Drilling Brass

CNC EDM Drilling 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.

How to Order CNC EDM Drilling Brass

Ordering Brass parts is straightforward. Provide the drawing, material, quantity and any certification needs. Our engineers reply — in English — with feasibility, pricing and a realistic lead time, usually within one business day.
