By leveraging electric discharge machining, it is possible to machine through any material or substance as long as it is conductive.
FREMONT, CA: Using electrical discharge machining in conjunction with a traditional machining method such as CNC is an excellent choice for parts with specific geometrical requirements that are not accomplished using traditional machining methods. This machining method is well suited for tasks due to the machining process. The process can machine hard materials like Inconel, making it a perfect option when working with materials.

Electrical discharge machining offers several benefits, including cutting forms and depths that are not achievable with conventional machining techniques. These include interior corners that are precisely square and with undercuts. Another advantage is that there are no burrs produced during the machining process.
Free-from-distortion machining
In contrast to traditional machining techniques, this approach never involves the tool making physical contact with the workpiece. There is no distortion when no forces are acting on the portion. It makes it possible to machine incredibly thin features without worrying about them breaking. Furthermore, the absence of distortion allows for very tight tolerances of +/- 0.012mm.
Superior surface polish
Traditional material removal techniques, like CNC milling, produce machining markings on the workpiece for cleaning up during post-machining. EDM produces surfaces with zero-directionality, allowing uniformly smooth surfaces without needing extra processing. However, rapid EDM processing can leave a faintly bead-blasted texture behind.
Material hardness is not a factor
One of the main advantages of electric discharge machining is that it can machine through any materials as long as it is conductive. In this way, in addition to Inconel, tungsten carbide, and other tough materials, it is possible to machine these materials.
Precision
Due to its high levels of precision, EDM is one of the best for making small components and prototypes despite its limited efficiency in producing big-volume orders. For instance, this method is frequently used in the automotive sector, where producing sophisticated engine components demands high precision.
