What is micro spark erosion?

Micro EDM milling owes its name, among other things, to its extreme micro-level precision. Accuracy of up to 1 micron (one-thousandth of a millimeter) on a tiny surface is standard with this technique. In short: everything that is possible with traditional milling can be done with micro EDM milling down to micron level.

This makes micro EDM milling a high-demand application for three-dimensional material processing for the high-tech industry and the medical world, among others. Micro EDM milling offers numerous new opportunities for these industries, in which the challenges are becoming more acute.

With its advanced machinery, Ter Hoek can manufacture almost any shape and always with extreme precision. As we properly monitor the wear of the electrode, the machining quality remains consistently high during the computer-controlled process.

Advantages of micro spark erosion

Micro EDM milling distinguishes itself as a machining technique by combining the advantages of die sinking and hole-drilling EDM. This makes it possible to apply refined details in a workpiece with a relatively large depth and accuracy of one-thousandth of a millimeter. Blind contours in complex shapes with sharp internal angles are no problem at all.

Timely replacement of the electrode prevents wear and ensures that extreme accuracy is maintained. This ensures the best results when machining materials such as aluminum, copper, steel, and carbide. During the micro EDM milling process, the machined material is washed away as residue along the outside of the electrode.
