EDMs, or electronic discharge machines, are computer controlled machine tools designed to use electrical discharges or sparks to make a desired shape in a metal. An EDM machine could be interchangeably called spark machinery, die sinking, spark eroding or wire erosion since metals are subjected to different electrical tactic to find the desired design or shape.
There are two main types of electronic discharge machines.
A sinker EDM which uses an insulating liquid (oil or dielectric fluid) to utilize electrical discharges and a wire EDM that utilizes a single strand of brass wire to make deep cuts within the metal. Other popular types include small hole and spark EDM’s.
There is a long list of industries that use these machine tools. From manufacturing coins to fabrication of car parts, these industries plus much more have benefited from the precision and effectiveness of assorted EDM machines. In mould production or advance of prototypes of any machinery component, they may be indispensable being a mould-making tool. Countless industries like automotive, electronics, mechanical and aerospace industries manipulate parts and components which are produced using these machines.
EDMs will also be used in processes requiring precise and accurate cutting or forming. A tiny hole drilling EDM is employed to create holes in metal parts so that large plats may be eroded to the metal without needing pre-drilling. This technique can be used in several industries to produce parts including turbine blades in jet engines, different components for fuel systems, and many more.
Why are EDMs preferred over other computer controlled cutting machines?
• These machine tools can cut hard metals in accordance with any set design which may ‘t be possible using other sorts of traditional cutting tools. They are able to shape extremely hard metals that are impossible with many different other cutting equipment and tools.
• These are built to create good quality, precision finished products. Difficulties with final product outcome are eliminated nevertheless there is no point of contact in between the unit and the metal or work piece.
• Fundamentally a metal spend the an excellent surface finish because of the critical cutting
ability from the tool. Even fine holes are possible with the EDM which is impossible to recreate using any standard cutting tool.
• The production speed could be slower when compared with high volume production cutting tools nevertheless the end product is as good since the prototype.
• The use of oil-based insulating fluid adds to the way the pad is cut. This ensures precision and impressive final results which can reduce material costs.
Although most common problem with excessive wearing of tool parts is inevitable in most EDMs, parts and precision components are usually easy to locate.
Additionally, there are most companies that provide repair and maintenance services. These machines do typically need a good deal of maintenance and efficient handling.
However, well-maintained units provides numerous years of precision service.
An EDM machine is indispensable it doesn’t matter what industry it’s employed in, so make certain you trust merely the most efficient EDM distributors in your niche for equipment, parts, restore.
