1. They Can Complete Large Jobs
Generally speaking, traditional machines are made to operate primarily in automated situations, but they require upkeep. On the other hand, EDM machines are less prone to errors or interruptions and thus may be left to operate with little supervision.
2. They're Amazingly Accurate
Some traditional machines can't be used in specific situations, such as when cutting sharp internal corners. For EDM machines, especially wire-based models, this is not the case. With the right kind of wire, tension, and feeding, it's possible to cut interior corners that are sharp and tightly packed and ultimately produce designs that would not be feasible using other techniques.
3. They're Capable of Deep Cuts
The materials frequently used in a machine shop are challenging to work with because they are so hard. This often meant developing designs that used shallow cuts to reduce the amount of effort required to make the cuts. EDM machines can make deeper cuts, even with very hard materials.
Additionally, such cuts won't cause ineffective or problematic seams. In other words, regardless of how deep it must cut, the tool consistently produces a clean, dependable cut regardless of how strong the material.
4. They Create Robust Molds
Due to the technology's ability to cut through solid materials, operators frequently choose EDM machines over standard CNC machining when creating molds.
Sometimes, to make a mold, two machining methods will be employed-first, a CNC mill will be used to make the negative shape, and then a wire EDM will be used to make the edges more precise. This is an excellent method for creating an injection mold. Furthermore, because the finished mold materials are so much stronger, costs are reduced because they need to be replaced less frequently. However, it also opens up a more comprehensive range of possibilities than would be conceivable with delicate or one-use molds.
It is possible to completely rethink machining and production when the molds made by EDM are combined with additive manufacturing techniques.
5. They Work Best with Hard Materials
Many materials, including some of the toughest in the field, may be bored through and cut with EDM devices. Even when meeting strict standards, the toughness has little impact on precision or maneuverability.
An EDM tool can effectively cut all conductive materials including tungsten carbide, hardened steel, titanium, Inconel alloys, and even materials like Hastelloy, composed of nickel and molybdenum. It is nearly impossible to cut these materials accurately using conventional cutting and machining techniques.
6. They Can Design A Distinctive Finish
EDM tools can indeed create surfaces like craters and pockmarks depending on the speed of the cut; this is typically the case when cutting swiftly. This can be a benefit when altering different parameters. For instance, cutting at lower power minimizes flaws and yields a smoother surface with a mirror-like gloss.
Operators can make adjustments to enhance the completed product and cut down on extra stages. Other tools are not required to obtain the same result because you can attain that mirror-like finish. This helps provide excellent work while also accelerating overall output.
