Electrical Discharge Machining (EDM)

Electrical Discharge Machining (EDM)

EDM machining is a process by which electric spark erosion is used as a cutting tool to remove metal under controlled conditions. The spark literally erodes the workpiece. We can then transform the eroded workpiece into the desired size and shape.

This tool can be used to cut holes and pockets into hardened steel. EDM is often used to fashion square pockets. It’s also used to impart a surface texture to the internal cavities of mold tools.

A high-powered electric spark is discharged by a sacrificial electrode residing in an electrolyte bath. The electric spark can erode extremely hard materials that would resist erosion with any other method.

Wire EDM is a variation of EDM. In this case, an electrically charged wire that’s fed continuously between two spools can cut through-hardened tool steel at high speed with impressive accuracy.

Aria is a professional CNC machining manufacturer in China, The reliability and precision of high-tech tools powered by sophisticated software programs give CNC machining the ability to quickly generate prototypes and complicated end-use parts having exceptionally tight tolerances. with low cnc machining costs from Chinese.

CNC machining is a subtractive manufacturing process. When the material is added instead of removed, it’s called an additive manufacturing process. Examples of subtractive CNC machining include specialized applications such as CNC milling services, turning, surface grinding, and EDM. An example of additive CNC machining is 3D printing.

Computer-aided design (CAD) files are digital records containing 3D designs and information about materials, processes, tolerances, and other variables. A digitally controlled CNC machine must always contain a file of the part design that controls it.

The spinning motion from the CNC machine’s cutter will leave visible tool marks. Although they stand ready for immediate service, they can be further refined with anodizing, painting, polishing, and plating.
