CNC Sinker EDM Hard Alloys

VT machining provides CNC Sinker EDM Hard Alloys for customers who need accurate, repeatable Hard Alloys components. Because Hard Alloys is wear-resistant carbide and hardened tool materials, we adapt the process to suit — controlling the variables that matter for this alloy.

CNC Sinker EDM Capability for Hard Alloys

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

How CNC Sinker EDM Hard Alloys Works

Material is removed from the Hard Alloys 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.

We start from your supplied geometry and tolerance scheme. The setup is designed to minimise re-clamping, which protects positional accuracy across features. A first article is verified against the drawing before the balance of the batch is released.

CNC Sinker EDM Quality & Inspection

Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.

Design Tips for CNC Sinker EDM Hard Alloys

Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened Hard Alloys 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

Most Hard Alloys parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.

Working with Hard Alloys

Hard Alloys is wear-resistant carbide and hardened tool materials. We translate those properties into a process plan: the right tooling, speeds, feeds and fixturing for the alloy.

Where the grade, temper or heat-treat condition matters to performance, we confirm it with you and can supply material certificates. Material is procured to recognised standards for consistent, repeatable results.

CNC Sinker EDM Tolerances & Surface Finish

EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the Hard Alloys part, producing fine, controlled surface textures and sharp internal corners impossible to mill.

The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.

Applications of CNC Sinker EDM Hard Alloys

Hard Alloys parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

How to Order CNC Sinker EDM Hard Alloys

Starting your project takes one email. Send your CAD or 2D drawing, the Hard Alloys grade and condition, the quantity and any finish or inspection requirements. We respond quickly with price, lead time and any DFM notes, in clear English.
