CNC Wire EDM Kovar

Looking for reliable CNC Wire EDM Kovar? VT machining manufactures Kovar parts to tight tolerances and consistent quality. Kovar is matched thermal expansion for glass/ceramic seals, so the process is set up specifically for the material.

CNC Wire EDM Capability for Kovar

• Kerf from 0.1 mm
• Tolerance to ±0.002 mm
• Hardened & exotic alloys
• Sharp internal corners

How CNC Wire EDM Kovar Works

Material is removed from the Kovar 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 Wire 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 Wire EDM Kovar

Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened Kovar 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 Wire EDM Tolerances & Surface Finish

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

Secondary Operations & Finishing

Most Kovar 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 Kovar

Kovar is matched thermal expansion for glass/ceramic seals. 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.

Applications of CNC Wire EDM Kovar

Kovar 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 Wire EDM Kovar

Starting your project takes one email. Send your CAD or 2D drawing, the Kovar 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.
