The Various Types Of EDM
EDM is short for Electrical Discharge Machining. Machining metal in an incredibly precise and accurate way is the foundation of this technique. When creating a part or other piece that needs to have extremely exact tolerances and would in any other case be impossible to produce, EDM is used. As such, EDM parts and machines are incredibly specific and precise pieces of equipment.
If the metal conducts electricity, Electrical Discharge Machining can be used. Large amounts of electricity are discharged in a precise way so that the metal is eroded to a design. Making parts for machines, intricate designs or extremely small gears that are difficult to make otherwise are a few of the uses of this process.
Ram EDM, Drill EDM and Wire EDM are the three forms of EDMs. RAM EDM is the oldest form of this machining technique, and requires an electrode made of graphite that is thrust into the piece of metal that is being worked on. When the electrode is pushed into the metal, a cavity is created. While it is mostly used to make indentations and cavities, it can also be used to make holes entirely through the piece of metal or specific types of geometry.
Revolving concentric electrodes that drill right through a piece of metal are utilized by a Drill EDM. This is comparable to a standard drilling process, but the hardness of the material is not a issue at all. Considerably more precise and clean finished work than is possible with a drill press is the outcome. There are a wide array of uses such as aerospace and medical equipment because of the fact that holes as minute as .006 inches can be achieved.
And ultimately, a small wire electrode that moves through or around the metal that is being handled is the foundation of Wire EDM. Oftentimes, a drill EDM might be used to create a hole for the wire, and then the wire is used to make the geometry of the piece itself. Very precise computers control these wires which can create incredibly intricate pieces.
When a precision piece of metal is required, either as part of a bigger machine or as a piece of useful metal by itself, EDM is normally used. Since EDM can be used on extremely hard materials, then the resulting pieces are very sturdy and useful in many situations. The aeronautics industry particularly makes great use of EDM for both its accuracy and the longevity of the pieces produced.
Another interesting piece of the process is that EDM occurs underwater. Certain flammable or explosive materials can be used with EDM whereas other technologies might set it alight or cause it to explode, which makes this very beneficial. Due to the filtering system that is utilized, there's a decreased risk of fumes and particles leaking out into the air which decreases risk of exposure for those doing the machining work.
Since EDM machines are precise devices, the parts may have to be replaced regularly. The entire process is not only accurate, but it is also comparatively cheap due to the fact that EDM parts, especially the wires used in wire EDM, can be obtained and replaced relatively cheaply.
It's still in wide use today, even though EDM was developed in 1770. Thanks to the different varieties of EDM available, almost any part can be created with great precision and to any specification.
