  • Graphite and the Role it Plays in EDM

    When it comes to electrical discharge machining, there are various methods, tools and materials that can be used in the processing. The process is used to fabricate metals including aluminum, copper, zinc, bronze, tin, silicon, titanium, stainless steel, gold, lead, silver, iron, cobalt, nickel, tungsten and much more. In EDM, electrodes are used to wear away, or spark away, the metal to create the desired shape. Common electrode materials include brass, copper and graphite. Graphite is an especially useful electrode because of its conductivity and temperature resistance. This makes it...

  • History of EDM Machining

    The process of EDM, or electrical discharge machining, has been around for a long time and is becoming more popular everyday. EDM got its start in 1770 with an English physicist by the name of Joseph Priestly. Priestly was studying the damaging effect electrical discharge could have on different items that were exposed to it. After his work, not much happened for almost two hundred years until two Russian scientists by the names of Dr. B. R. Lazarenko and Dr. N. I. Lazarenko began to study the same effects. Through...

  • CNC EDM Involves Fewer Mistakes

    Computer technology is taking over our lives. That is a fact that few would argue against, but many do argue whether this technology is a good or bad thing. When it comes to manufacturing, it can easily be argued as a good thing. Movies such as IRobot and the Matrix show the hazards of letting computers take over too much. Yet, at the same time we see the unbelievable advantages in the medical industries. Computer technology in industry is able to minimize the risks of human injury, and accuracy is...

  • EDM's in the Precision Field

    EDM machining is probably not like every other process you know. When it comes to producing precision products, it is one of the industry leaders, yet it can be costly, so many settle for less quality goods at more affordable prices. However in many industries, the best is necessary. For example the medical industry cannot be using roughly cut pieces for transplants. Can you imaging receiving a jagged rod or screw in you broken leg or newly replaced hip? Do you want to find out that the needle they used...

Industry Information

EDM Machining

EDM machining is a tooling method that uses electrical energy to cut, drill, etch and machine metal parts and is one of the most accurate types of machining for hard metals and other materials that are difficult to machine cleanly with conventional mechanical-cutting methods. Some of the common applications for electrical discharge machining include producing plastic molds, die casting dies from hardened steel and forging dies.

EDM machining is a tooling method that uses electrical energy to cut, drill, etch and machine metal parts and is one of the most accurate types of machining for hard metals and other materials that are difficult to machine cleanly with conventional mechanical-cutting methods. Some of the common applications for electrical discharge machining include producing plastic molds, die casting dies from hardened steel and forging dies. EDM erodes the material in the path of the EDM tool using electrical discharges, or sparks. These electrical discharges can generate heat anywhere from eight to twenty thousand degrees. This process takes place in a bath of dielectric fluid, which prevents premature sparking and flushes away debris, conducts electricity between the electrode and the work piece and then flushes out the melted material. The tool electrode forms an arc to the work-piece electrode as the two are brought closer together, creating the intense electric field which is responsible for removing material. There is no actual contact between the electrode and the work piece, but rather a conductive path that is established between the electrode and the material. Industries that benefit from the use of the EDM cutting process include food and beverage, automobile, stamping, extruding, defense, electronics, aerospace and medical.

Diverse materials that can be used in EDM machining include aluminum, copper, zinc, bronze, tin, silicon, titanium and stainless steel. EDM machining services are engineered towards specific applications and wire EDM and sinker EDM are the two main types of EDM machining services. Sinker EDM is capable of boring holes into metal work pieces, creating holes, patterns and at times three dimensional objects, while wire EDM cuts patterns and shapes. Wire EDM is used for cutting shapes through a selected part or assembly. Sinker EDM is used for more complex geometries where machined graphite or copper electrodes are used to erode the desired shape into the part or assembly. CNC machines are used to guide, monitor and control the electrical discharge machining process, as well as CAD and CAM software. EDM machining has advantages over other machining techniques due to its ability to create complex and intricate parts with a high degree of accuracy. Another advantage of EDM machining is its ability to machine parts on an extremely small scale. While using this process, the work piece is not deformed from impact because there is no direct contact between the electrode and the material, and likewise the work piece is burr-free after completion and saved from heat damage because very little material-damaging heat is generated during the procedure.
