EDM & grinding

EDM and ground precision parts.

Wire EDM, sinker EDM and precision grinding to your drawing, from one piece. For parts where milling and turning reach their limits: hardened materials, fine internal contours, maximum flatness. Upload drawing and 3D model and get a price instantly.

Processes

Three processes for maximum precision

01

Wire EDM

A thin wire cuts contours out of the workpiece without cutting forces – even in hardened steel. Ideal for punches, die plates and fine internal contours with sharp corners.

02

Sinker EDM

An electrode forms cavities, blind holes and ribs that cannot be milled. Typical for mould inserts and toolmaking, with a mirror finish if required.

03

Precision grinding

Surface and profile grinding for exact flatness, parallelism and fine surfaces – also as finishing for your milled and turned parts.

Capabilities

Which parts we EDM and grind

  • One-offs and prototypes – without minimum quantity
  • Small series – larger series on request
  • Typical parts – e.g. punches, dies, die plates, mould inserts, guide rails, precision parts with fine internal contours
  • Hardened parts – machining after hardening, without distortion from cutting forces
  • Combined – milling or turning, hardening, EDM and grinding from one source

Lead time

Fast when it’s urgent – cheaper when you have time

Thanks to fixed capacity agreements with our partners, express is our standard. The instant quote shows both prices side by side – so you can see how much you save if you allow a little more time.

Quality

Measured, not estimated

All our manufacturing partners work to ISO 9001:2015 and inspect with coordinate measuring machines, roughness and hardness testing. You can order an inspection report, e.g. a measurement protocol, as an additional item with your order. Throughout the order we are your single contractual partner and contact.

Security

Your drawings stay confidential

Data is transferred encrypted, and manufacturing drawings are passed on to our manufacturers anonymised. On request we sign a non-disclosure agreement (NDA).

FAQ

Frequently asked questions about EDM and grinding

When is EDM better than milling?

For hardened materials, sharp-edged internal contours, very fine slots or deep cavities. EDM works without cutting forces, so the part does not distort.

What data do you need for a quote?

A technical drawing as PDF and the 3D model as STEP file (.stp/.step). You only have a drawing? We create the 3D model – as a design service at extra cost, please request individually.

Is there a minimum order quantity?

No, we manufacture from one piece.

Can you also harden and then grind?

Yes. Heat treatment such as hardening, nitriding or stress relieving and the subsequent finishing are available from one source.

Do I get an inspection report?

Yes, on request. You select it as an additional item when ordering.

Where do you deliver?

To Germany and Austria.
