While graphite materials can be used to machine carbide materials, it is not the best method. One of the reasons is the extremely high electrode wear rate. Burning with a fine-grain graphite, such as DS4 or POCO-3, will lead to 50-60% electrode wear when used to...

When choosing an electrode material, you must consider many factors. The usual first decision is, should you choose a metallic or non-metallic electrode? Depending on the material to be removed, this can be as simple decision. Carbides and sintered metals require more...

Ram type (also called sinker type) EDM was the first type of Electrical Discharge Machining used in the manufacturing process. I was lucky enough to see the first EDM machine made for the purpose of eroding metal. Most historians give credit to a metallurgist couple...

Sinker EDM, also referred to as Ram EDM, uses electrodes machined from graphite or copper to shape the workpiece. Typically found in die/mold component manufacturing, a Sinker EDM raises and lowers (sinks) the electrode along the workpiece. Regardless of the name you...
