EDM as a manufacturing process offers many unique advantages. Some of these benefits include:
Greater Design Freedom
EDM allows manufacturers to cut shapes and depths that may be impossible for the traditional manufacturing processes. These cuts include perfectly squared internal corners and undercuts, creating parts with thin walls. Wire EDM easily cuts thin slots in extrusion dies better than conventional methods.
Micro EDM is the best option when cutting internal corners with very small radii. This technique has the unique capability of creating an inside corner in CNC machining. In addition, many manufacturers rely on this technique to produce non-round openings and cavities in their workpieces. Meanwhile, engineers can create blind and high aspect ratio pockets with sinking EDM.
Distortion-Free Machining
The tools involved in electric discharge machining do not directly come in contact with the workpiece at any point. Hence, the workpiece does not suffer any form of deformation or disfiguration in the process. This is because there are no forces applied to the material. This allows easy machining of fragile parts without the fear of damaging the parts. In addition, the absence of distortion in this process means it achieves a very tight tolerance of about +/- 0.012mm.
High-Quality Surface Finish
EDM creates surfaces with high precision and smooth finishes. Most manufacturers often subscribe to applying this method as an injection molding surface finish. It provides more excellent results than other common traditional surface finish processes.
Precision
Even though EDM has limited efficiency in manufacturing large orders, EDM is an ideal method for manufacturing small parts and prototypes. This is because of its outstanding level of precision. EDM has an excellent application level in the automotive industry and aerospace industry. This is because it can deliver high measurement accuracy levels to create complex engine components.
Work on Hard Material
Most conventional machining methods need to be applied before solidifying the workpiece. Rigid materials like Tungsten carbide, Inconel, and hardened steel may not be easily machined. On the other end, EDM is a method compatible with hard materials. This is one of the essential benefits of the EDM method. It works well with any material available material with great conductivity. In addition, it also prevents any possible deformation from the heat application.
