Electrical Discharge Machining in Bohemia, NY

At Refracto Technologies Corp., we specialize in electrical discharge machining in Bohemia, NY, also known as EDM. This metal machining process uses a tool that discharges thousands of sparks to a conductive workpiece. Unlike conventional metal cutting, EDM machining works on parts or components made of hard-to-cut materials. We supply EDM services to your parts or components, machining contours and features to your exacting specifications. We can also supply parts complete from raw material to your drawings.

How EDM Works

Electrical Discharge Machining is a manufacturing process that uses electrical discharges or "sparks" to obtain the desired shape of an object made of hard metals or material. The series of rapidly recurring current discharges between electrode and work piece causes the material removal from the work piece, separated by a dielectric fluid and subject to an electric voltage. One of the most common types of EDM is die sinking, where the work piece is submerged in an insulating liquid (dielectric fluid) and a suitable power supply connects it to an electrode. The EDM die sinking process is commonly used by mold-making, tool, and die industries, as well as aerospace, auto, medical, and electronics industries. Other types of EDM include wire and plunge.

Why Choose EDM

Where conventional machining is not possible for hard metals or difficult features, EDM machining is an option that can be relied upon for cutting with accuracy and precision. Since there is no mechanical contact in EDM machining, it allows contours and features to be machined that are not even possible with conventional machining techniques. This includes very delicate features such as thin walls and sharp corners. At the very least, EDM can make an otherwise very difficult conventional machining operation very easy.
