With state-of-the-art wire EDM machining equipment and advanced programming, we can manufacture even the most intricate parts with perfect accuracy and repeatability, whether you need prototypes, short production runs, or quantities in the tens of thousands.
What is the Wire EDM Process?
Wire electrical discharge machining is a high-precision method for cutting nearly any electrically conductive material. A thin, electrically charged EDM wire held between upper and lower mechanical guides forms one electrode, while the material being cut forms the second electrode.
Electrical discharge between the wire and the workpiece creates sparks that rapidly cut away material. The electrode leaves a negative imprint in the workpiece, like pressing into a soft material. Submerging the workpiece and wire in deionized water allows cutting debris to be flushed away.
As the charged wire never makes physical contact with the workpiece in EDM machining, there are no cutting forces involved, making it possible to manufacture tiny and delicate parts. EDM machining is ideal for parts that require levels of accuracy and intricacy that traditional machining cannot achieve can easily be produced via wire EDM.
Advantages of Wire EDM Machining
Wire electrical discharge machining can work on any hard, conductive materials without damaging or compromising the finished product. Because of this, there is no need for additional thermal treatments, unlike other EDM machining services.
WEDM also puts less stress on the machine part, reducing the chances of distorting or damaging the finished components. Because the wire EDM process puts less pressure on the part, it’s also easier to produce fragile outlines.
EDM machines offer a broad range of benefits that other manufacturing methods can’t match. Some other reasons to choose a Wire EDM Machine include:
- Precision: When you need highly accurate machining, EDM manufacturing is your best option. It is capable of making cuts that match your designs within ± 0.0001”.
- Intricacy: Wire EDM is an excellent option for manufacturing delicate and intricate parts. With Wire EDM, it is possible to manufacture the same intricate part over and over again with the same accuracy.
- Shorter lead times: Because the EDM process is so accurate, it makes it possible to significantly shorten the lead time by getting it right on the first try. Decreasing the time it takes to get a product from the prototype phase to the marketplace.
- Less set up time: EDM manufacturing reduces the need for tooling, which in turn lessens the amount of time that it takes to set up.
- Tapers: EDM machining is useful for cutting long tapers that other machining methods cannot produce.
- Accurate internal cuts: Square-edged internal cuts are difficult to produce with other machining methods, but Wire EDM makes it possible.
- Better results: EDM machining is capable of producing parts that don’t have burrs or require tooling. Wire EDM also creates a better surface finish than other forms of manufacturing.
- Fine hole drilling: EDM drilling is capable of producing tiny holes that are difficult to produce with other methods.
Why Choose Wire-cut EDM Over Die-sink EDM or Water-jet cutting?
Concerns about residual stress are often the primary reason why manufacturers choose Wire-Cut EDM over other methods. Residual stress can contribute to premature failure of a part, so to avoid creating residual stresses during the manufacturing process is to extend the life of the part.
Wire EDM creates minimal residual stress. Moreover, preventing residual stress eliminates the need to relieve those stresses – this is just another example of how Wire EDM makes the manufacturing process efficient.
What Kind of Materials Can Be Used?
Materials like steel are difficult to cut or mold without adding heat first. Wire EDM makes it possible to cut steel through and other materials without applying heat.
Wire erosion works best with materials that conduct electricity, such as:
- Carbon graphite
- Carbon steel
- Stainless steel
These materials can be very costly. An excellent way to keep costs low is to live by the old adage, “measure twice and cut once.” When machining results in inaccurate cuts or fails to reproduce parts with the same level of accuracy, these expensive materials can go to waste. Because EDM machining is so accurate, it can prevent waste of raw materials and keep your project cost-efficient.
Industries and Innovations: Who Uses Wire EDM?
Wire EDM-manufactured parts are everywhere, touching every part of our lives. Starting a car, boarding an airplane, or booting up a laptop are all possible thanks to electrical discharge machining.
For instance, Wire EDM makes it possible to cut steel without treating it with heat first. As a result, EDM manufacturing is a preferred choice for medical device manufacturers who make life-saving instruments out of carbon steel.
Because EDM drilling makes it possible to create very small holes, EDM is used often in the production of circuit boards. The military and aerospace industries also rely on Wire EDM manufacturing to produce parts for essential equipment. Even automotive manufacturers turn to Wire EDM for its precision and efficiency.
In addition to these applications, EDM machining is also found in:
- Small volume productions
- Mold and die manufacturing
- Metal components manufacturing
- Applications that require low residual stress
