Metal disintegrators are primarily used for bolt removal, tap removal, stud removal, drill removal, and seized or broken bolts. So spark eroders are the machines that are used in the electric discharge machining field. However, spark eroders produce sparks in the application, and metal disintegrators do not. This is a common term used throughout the UK. Our metal disintegrators are sometimes referred to as Spark Eroders. Spark Eroder, Spark Burner, or Spark Disintegrator (You may have heard these referred to as Metal Disintegrators) Learn more about the spark erosion process.
We use this method on many different types of metals and alloys, such as Monel, Titanium, Tool Steel, Tungsten Carbide, Tantalum, Super Duplex, and Inconel. EDM normally operates with materials that are electrically conductive and is designed to erode (remove) intricate depressions or contours from pre-hardened steel negating the requirement for heat treatment to soften and re-harden the steel. Spark erosion is a form of EDM or electric discharge machining that is a machining technique principally used for hard metals and metals that are difficult to machine using traditional methods. Spark erosion is sometimes miscommunicated as being metal disintegrating but it is not. Adding new liquid dielectric in the inter-electrode volume is commonly referred to as “flushing.” Also, after a current flow, the difference of potential between the electrodes is restored to what it was before the breakdown so that a new liquid dielectric breakdown can occur. Once the current stops (or is stopped, depending on the type of generator), the new liquid dielectric is usually conveyed into the inter-electrode volume, enabling the solid particles (debris) to be carried away and the insulating properties of the dielectric to be restored. As a result, the material is removed from the electrodes. This phenomenon is the same as the breakdown of a capacitor (condenser) (see also breakdown voltage). When the voltage between the two electrodes is increased, the intensity of the electric field in the volume between the electrodes becomes greater than the strength of the dielectric (at least in some places), which breaks down, allowing current to flow between the two electrodes. One of the electrodes is called the tool-electrode, or simply the “tool” or “electrode,” while the other is called the workpiece-electrode, or “workpiece.” The process depends upon the tool and workpiece not making actual contact.

Material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage. Electric Discharge Machining (EDM)Įlectrical discharge machining ( EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a manufacturing process whereby a desired shape is obtained by using electrical discharges (sparks). There is no faster or efficient or cost-effective method to remove broken tools, studs, or fasteners than MDM. Typical application includes broken tool extraction (taps, drills, reamers, drill bits) metallurgical sample excavation, and bolt removal.
MDM uses a spark erosion process commonly used for destructive cutting. The metal disintegration process removes a tap, bolt, or drill leaving the hole intact and allowing a part to be reclaimed. Metal Disintegrators or MDM machines are manufactured for the specific purpose of removing broken tools from workpieces. Our arc process literally vaporizes the metal to be removed in a controlled way. By contrast, our arc is a powerful current path operating at very high temperatures like in carbon-arc searchlights. Aside from superficial campfire embers, sparks are relatively low-power, momentary electrical effects like those in automotive spark plugs to ignite fuel. Terms like “spark eroder, spark erosion, spark burner, or spark disintegrator” are misleading and incorrect. On the other hand, “MDM” stands for Metal Disintegration Machine, which is what we build. EDM machines are also MUCH more expensive. Electric Discharge Machining is much more precise than arc disintegration but also very slow. “EDM” is the correct term for a very different process.
