What Are the Key Benefits of Electrical Discharge Machining?

Electrical Discharge Machining – often referred to as simply EDM – is a widely used manufacturing technique that is used to create certain shapes and work with typically difficult materials that more conventional mechanical machining techniques cannot. Although all techniques have their advantages and disadvantages, EDM has certain benefits that make it a popular machining method.

One of the main advantages of EDM is that it can be used to create shapes from a variety of different – and generally very difficult – materials, including hard substances such as Stellite, Nitralloy, Tungsten Carbide and several more. Whereas other machining methods may be ineffective here, Electrical Discharge Machining can be very successful, and is therefore a method of choice.

As a result, parts manufactured by this particular method are sought after in various industries, including the aerospace, electronics, defence and automobile sectors. This particular method can allow very specialised and essential components to be manufactured, especially where traditional and conventional methods fail to deliver.

This is important as many of the industries above strive not only to innovate and provide new, more effective products on a frequent basis, but they also require high quality parts made of very specific materials. Having a tool on hand that is capable of meeting the diverse and highly specific needs of these industries can mean that complex and difficult designs can become reality.

The next major advantage of this particular technique is that it can create very complex shapes, whereas other more conventional methods cannot. This is another very distinct benefit which means that this particular production method is very popular with industries such as the aerospace and motorsports sectors where specialisation and precision are very important indeed.

This leads on to another benefit, which is that due to the ease by which this particular method can create complex shapes, production of components and parts is much more efficient than with conventional machining techniques. Whereas other tools may create these more complex shapes with difficulty, EDM is a faster and far more efficient solution.

For many companies and manufacturers this is an extremely attractive quality, as it means that projects are completed in much smaller amounts of time, and that brand new products can be released onto the market much more rapidly than ever before. There will also be less time and money poured into the production process when it can move along far more rapidly.

In addition to being able to create complex shapes with ease, EDM is also used for creating fine holes, which again is not normally a simple task with other production and machining techniques. Holes created can be of any width, and the unique techniques that are employed with EDM make it possible to obtain absolute precision.

Again, this level of precision and the efficiency of this method where others fail are extremely valuable to numerous companies in various industries. Again, sectors which require specialisation, absolute accuracy and reliability such as the electronics, automobile and aerospace industries are very likely to place value in the benefits of Electrical Discharge Machining.

Finally, another major advantage of this particular method is that it allows for a good or very good surface finish, as it relies on a no-contact technique. Furthermore, this no-contact method is highly suited to fragile parts or delicate materials which would otherwise be distorted or damaged by more forceful techniques.

These are just a few of the many advantages of EDM, including the ability to create complex and precise shapes right through to the ability to work with very hard materials. For these reasons, this production method remains highly popular with a number of manufacturers in various industries, and as yet is unrivalled in its unique capabilities.
