Nowadays, technology in metal forming is rapidly developing and changing according to the need for high accuracy and better work quality. EDM is considered to be a popular machine since it can greatly respond to the industrial needs.
EDM or Electrical Discharge Machine is a metal milling machine that relies on the release of high-voltage electricity into an electrode made of high conductivity material such as copper or graphite, to cause a spark on the work so that the work is heated and erodes to the shape as designed in the CAD/CAM systems. The work that is popular to use with EDM is a specific work with high complexity, difficult to produce, unable to be produced or cut with CNC milling machine, or work that is produced with a specific material or has been hardened, mold production, or prototype, etc. Moreover, entrepreneurs have seen the advantages in using EDM as a part of the production process to directly produce work due to the high accuracy in the work since there is no work debris that interferes with the production process. It can also provide better a quality and aesthetic work. Therefore, many industries, especially the aircraft industry and IT industry, have shown their interest and use it as a part of their production.
This machine is considered to be a popular machine and is greatly needed in the industry sector, especially in the auto parts business sector which can generate income in the top ranks of the country under high competition. Many entrepreneurs have started to emphasize enhancing their potential in production to obtain quality work from these high quality machines. Therefore, Mitsubishi Electric has presented NC EDM Systems EA-PS Series in response to developing the industrial efficiency of the customers.
EA-PS is a machine with the High-Accuracy level of NC EDM System that can smooth work surfaces up to Ra 0.05 um with an accuracy of + micron. Also, there is the Lotus Leaf Texture function. If used with electrode or copper, including IDPM or Integrated Discharge Power Master, which is a system that can control the sparks and reduce the erosion in Graphite Electrode, it will provide more accurate milling. SS Jump system, which has been upgraded, will also help the machine to operate 40% faster.
In addition, Mitsubishi has presented other products in the EDM Series, which is a popular model of Mitsubishi Electric with simple application and features in terms of its efficiency and value. NC EDM System EA-S Series can corrode metal work and special materials of type Tungsten Carbide, together with IDPM, which is the standard function of high productivity machines, suitable for smartphone, plastic mold, and automation. The usability is easy; only use your fingertips to touch a 15-inch touch screen to open 3 sides of the tank for convenience in placing the work. Both models can support operation with automation system effectively.
EDM is continuously developing according to the changes in the industry and the need for higher performance in production, especially the use of EDM in the production line of the auto parts industry which requires more complexity, more accuracy, and certainty. These machines must be able to coordinate with the operation and control the production automatically according to the production at the level of Industry 4.0 and beyond.
