Even though the vast majority of copper edm electrodes for injection mold making are machined by cnc machines, knowing how to grind copper is a valuable skill in the surface grinding process. there is always the odd job, or rework that requires manual grinding of copper. one of the main reasons copper is avoided is because it is difficult to grind and it requires additional.

However, copper has high electrical conductivity and strength. Brass is a copper and zinc alloy commonly used for wire EDM or small tubular electrodes. In contrast to the electrodes used for sinking, the wires used for EDM do not have to have good electrical resistance properties because new wires are continuously fed during the cutting process.

Generally, conductive materials can be machined using electrical discharge machining. The common materials comprise metal alloys or metals like solidified steel, titanium, as well as composites. Usually, the electrodes are made of graphite or copper for die sinking EDM.

With spark erosion, EDM spark temperatures many times higher than copper's melting point, certain applications using copper electrodes suffer from unacceptable electrode wear. With the advent of graphite as an electrode material, superior metal removal rates have been attained with far less electrode wear.

With copper electrodes, high current density on smaller, more intricate detail increases the electrode wear. Also, when machining intricate detail or EDMing at high current densities, a copper electrode may move or flex as material stress is relieved. This limits the ability to maintain the very tight tolerances required on many of today's molds.

Abstract. In this study, a multi-EDM grinding process is adapted to fabricate micro-electrodes. Equipments such as a wire EDM machine and a traditional CNC-EDM machine are used for machining micro-electrodes. Rod electrodes of copper with diameter 3.0 mm were cut to be 0.15 mm on wire-EDM machine at first step.

Metallic electrodes usually work best for EDMing materials which have low melting points as aluminum, copper, and brass. As for steel and its alloys, graphite is preferred. The general rule is: Metallic electrodes for low temperature alloys. Graphite electrodes for high temperature alloys. However, exceptions exist.

Sinker EDM (also referred to as conventional or ram EDM) utilizes a custom-made electrode that "sinks" a shape into a material. Electrodes – which are commonly made of graphite, copper, or tungsten – appear as a reverse, or negative, of the required shape.
