  • Amplify Advantages, Decrease Disadvantages

    The erosive capability of electrical discharge was first studied in the late 18th century, but harnessing this power into electrical discharge machining did not occur until 1943. Since then, EDM has been used predominantly in the tool and die industry, but is beginning to be used more and more in creating prototype and production parts in the automobile, electronics, and aerospace industries where production quantities are low. EDM is considered non-traditional machining along with processes like water jet cutting, laser cutting, and electrochemical machining. This is because mechanical force is...

  • Small Hole EDM for Miniscule Precision

    I can still remember the first time I saw the inside of a computer. My step-father runs his own communication systems business, and he is constantly taking things apart and putting them back together. When he would do this at home, I was fascinated by the tiny metal pieces inside. Each one was formed perfectly, and I could not imagine how they could have made each of those minuscule pieces so precise. One of the pieces was a perfect square, roughly the size of my fingernail, with tiny holes throughout...

Industry Information

Small Hole EDM

Small hole EDM, also known as fast hole drilling and start hole drilling, is a specialized tooling method that uses electrical energy to erode materials and produce holes in metals or parts that require close precision machining and repeatability.Small hole EDM services are used in industries including automotive, injection molding, tool and die, medical and appliance with a wide variety of applications such as removing broken drill bits, small hole placement, hardened punch ejector holes and aircraft cooling holes.

Small hole EDM, also known as fast hole drilling and start hole drilling, is a specialized tooling method that uses electrical energy to erode materials and produce holes in metals or parts which require close precision machining and repeatability. Small hole EDM drilling employs a round, hollow electrode that rotates around a spindle, similar to a drill and drill bit. A generator or power source electrically charges the electrode which then produces sparks or discharges, hence the term electrical discharge machining. The sparks erode the surface of the work piece by creating microscopic pockets that eventually create a small hole. The work piece is also attached to a power source and placed in a water-based dielectric fluid. As the electrode and the work piece are brought closer together, an intense electric field is created which serves to erode away the material of the work piece. The dielectric fluid is responsible not only for conducting electricity during the process but also for maintaining the temperature and flushing away the unwanted material debris. Small hole EDM services are used in industries including automotive, injection molding, tool and die, medical and appliance with a wide variety of applications such as removing broken drill bits, small hole placement, hardened punch ejector holes and aircraft cooling holes.

The process of small hole drilling can be used as an independent drilling process on specifically designed work pieces, or to make a through hole as a pretreatment for wire EDM which requires a hole to start the cutting process. Small hole drilling capabilities extend from .03mm to 6.1 mm holes and some can drill through 100 mm of soft or hard materials in less than ten seconds. CNC EDM machines are used to control the depth and location of the holes during the electrical discharge machining process, as well as CAD and CAM software to instruct the path of the electrode/s. The size of the hole created is controlled by the diameter of the electrode. Small hole EDM can be used for any hard or soft electrically conductive materials, which include stainless steel, titanium, aluminum, copper, carbide and hard tool steels. Some advantages that come with using small hole drilling services include the ability to drill on curved or angled surfaces, to drill through extremely hard or extremely delicate materials and to drill very deep holes, while remaining a fast, accurate and affordable process. However, there are some drawbacks to using small hole EDM which include a much longer drilling time for large holes compared to conventional drilling, an inability to control blind hole depth and significant electrode wear.
