Types of EDM Services at Entag

Wire EDM
Process

Wire EDM uses a thin, electrically charged wire to cut through materials with extreme precision. The wire moves along multiple axes, allowing for the creation of complex shapes and tight internal radii. It can work on both conductive and hardened materials, creating intricate patterns.

  • Can machine parts up to 500 mm thick
  • Achieves tolerances of ±0.005 mm
  • Excellent for cutting hard materials such as tool steel, titanium, and Inconel
Example Applications for Wire EDM
Aerospace Blisks

Spark EDM (Die Sinking)
Process

This method uses a shaped electrode to erode material by creating a negative imprint of the desired part. It is ideal for creating deep cavities, sharp corners, and complex surface geometries.

  • Material Depth: Machining deep cavities and complex geometries.
  • Achieves tolerances of ±0.01mm
  • Effective on hardened and tough materials like tool steels and titanium
Example Applications for Spark EDM

Hole Drilling EDM
Process

Designed specifically for drilling deep, small holes into hard-to-machine materials. A hollow electrode creates precise holes using electric discharges.

  • Ability to drill hole sizes as small as 0.1mm
  • Can achieve tolerances of ±0.01mm
