CNC machining and EDM technique technologies

CNC (computer numerically controlled) machining is a category of manufacturing processes involving precision computerized machine tools that transform raw materials into finished or near net shape machined component shapes through material removal via cutting tools. There are many CNC machine configurations, each with advantages and specialties.

EDM (electrical discharge machining) is a non-traditional process that uniquely removes material through a non-contact spark erosion process in a dielectric medium. EDM is another type of precision CNC equipment capable of creating different features & shapes with a few different machine types. This subset of manufacturing processes can work with some very difficult-to-machine and exotic metal alloys and is often used to generate shapes that are not possible or practical with conventional CNC machinings such as lofts, tapers, micro holes, extremely small corner radii features, and more.

CNC machining and EDM are ideal for medical component manufacturing. These high-precision manufacturing methods, programmed through advanced software and executed with high-quality machine tools, make it possible to create complex, robust, high-precision parts used in the most critical medical and surgical device applications.
