Machining the Impossible – Fine Hole EDM Drilling Services
EDM Intelligent Solutions offer unique, fine hole EDM drilling services of blind and through holes. Our purpose-built CNC operated EDM fine hole drilling machines can produce holes as small as 30 microns (0.0012”) in some of the toughest conductive materials available like carbide and nickel. High precision micro hole sizes, excellent hole edge quality, superior surface finish, improved overall part accuracy and excellent hole consistency is achieved through the use of cutting edge EDM generator technologies and electrode materials.
What is EDM Hole Drilling?
Similar to Sinker EDM, hole drilling with electrical discharge machining uses electric current, carried to the workpiece through a pipe shaped electrode, to erode or burn away conductive materials. The electrode doesn’t ever touch the material being machined so deflection of the pipe electrode is minimized when compared to drilling holes with a traditional cutting tool. During EDM Hole Drilling the tube electrode is energized and spun at high speeds while high pressure flushing is pumped through the tube to flush out the workpiece material that is being cut away. This process allows EDM Intelligent Solutions to produce fast and accurate holes in all types of conductive metals. Our EDM Drilling machines are designed for the highest levels of accuracy, incredible reliability, and uniquely integrated automation offers increased productivity which makes EDM Hole Drilling the perfect choice for projects with hole quantities ranging from just a few all the way up to high volume production applications requiring thousands of holes.
