EDM or spark erosion is a manufacturing process that precisely removes material from conductive materials using thermal energy or electrical sparks to obtain the desired shape. It is known for achieving its extremely high accuracy-Wire EDM Machining- Up to +/- 0.0001” inches typical tolerancesSinker or Spark EDM- Up to +/- 0.0002’’ typical tolerances)It is very popular due to its applicability especially for hard materials like titanium or for particularly complex shapes that are hard to achieve with milling.Perfect Tools provides both Spark EDM (Die-Sink) EDM services and Wire EDM Services.We also have access to EDM Hole Drillers.
