As growing machine shops like Logik Precision know, there is more than one way to make a part. We have expanded what we offer and acquired the equipment we have onsite to manage the best in additive and subtractive technology. One of the newest technologies that we have recently incorporated is EDM, or electrical discharge machining.
Considered a non-conventional technique, EDM emits a series of short, but repetitive, electrical discharges at high current density between the tool and the work piece. Because the electrode does not directly come in contact with the work piece, even the toughest and most brittle electrically conductive material responds well to the process. Three types of EDM known as RAM EDM, drill EDM, and wire EDM produce a wide range of intricate parts.
10 Compelling Reasons To Use Wire EDM
If you are new to the wire EDM process, here are 10 compelling reason to ask us about using this process on your next tough job.
1. Tough shape? No problem. Whether you have a part with complex shapes, conical sections, pockets, or tapers, EDM can handle it without burrs and without affecting the structural integrity of the piece.
2. Small parts, big results. The process works even on small work pieces at risk of damage from cutting tool pressure used in other processes. You can make parts that would be disastrous if you tried to use a mill or grinder.
3. Wide material flexibility. EDM works on all types of conductive materials at all hardness levels. Commonly used for machining dies, tools, and molds made of hardened steel, tungsten carbide, and high-speed steel, it opens new possibilities for the use of exotic materials used in aeronautical and aerospace such as Hastealloy, Nitralloy, Waspaloy, and Nimonic.
4. Nondestructive. Even on parts that need a series of holes, such as turbine blades for jet engines, the process makes adding holes easier with minimal heat penetration into the material.
5. Excellent for hole drilling applications. Aside from its applications with turbines, the process can create microscopic holes for other aerospace, military, and surgical applications. It also works well on non-rounded cavities and recessed cuts.
6. Thin walls. Because EDM is a no contact, no force, no deformation process, thin walls are a breeze, even on parts with deep complex cavities.
7. Tight tolerance. EDM parts are accurate within a tolerance of +/-.0002 or better with multiple passes.
8. Fine surface finish. Offering a surface finish similar to a ground surface finish with a fine wheel, an EDM part can achieve a near mirror finish with multiple passes of the wire. A matte finish is more common.
9. Great value. Because the process has a lower chip/work piece mass ratio, there is less waste of expensive materials. In addition, since the wire used in the EDM process is a standard off-the-shelf component, supplies are inexpensive.
10. Low-cost tooling. For short runs or low volume parts, you can use EDM without needing a set of costly dies.
Consider EDM For Your Next Job
Although variations of the EDM process have been around for centuries, the process is now coming into wide acceptance. At Logik Precision, we can tell you why this process might be better for your application than more conventional techniques like turning, milling, grinding, drilling, and other processes that remove metal. It is often categorized with other new machining technologies, such as laser cutting, waterjet cutting, and electrochemical machining.
The engineers at Logik Precision can help determine if you have a part that is a good candidate for wire EDM or any of our other innovative new processes. Contact us today at 713-939-0061 to learn more.
