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.

Copper is more efficiently cut on WEDM machines, which makes it cut much faster than graphite in WEDM. Highly detailed electrodes, which were formerly manufactured on surface grinders, required many hours of highly skilled labor. The use of copper and WEDM to produce these electrodes has dramatically changed EDM machining.

For graphite and copper tools the lowest values of volumetric relative wear were achieved for positive polarity. The best surface roughness Ra was obtained for copper electrodes under negative polarity. sinking EDM; graphite and copper electrodes; tool steel; process parameters

There are five commonly used electrodes: brass, copper, tungsten, zinc, and graphite. In addition, some electrode materials are combined with other metals in order to cut more efficiently. Studies show that graphite electrodes have a greater rate …

In EDM, reasonably electrode material selection is important to ensure ball core quality. Seen from the above analysis, comparing three different materials processing results, using graphite as negative electrode in the coarse grinding stage and using red copper as positive electrode in the fine grinding stage can achieve satisfactory effect ...

Grinding wheel

The grinding wheel or the workpiece is transverse to each other. 5. Wire EDM. One of the highly precise CNC machining technique is the Wire EDM (Electrical discharge machining). Wire EDM is also referred to as spark machining, die sinking and wire erosion method. Wire EDM makes use of either copper or brass wire with a high-voltage electric ...

For surface grinding with a straight wheel, use ... Both copper and graphite electrodes can be used to EDM Moldmax XL. Copper has better wear resist-ance but graphite is more machinable. Negative electrode polarity is most effective when working with …

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.

Electrical discharge surface grinding (EDSG) is a hybrid machining process with combination of electrical discharge machining and mechanical grinding. The grinding action along with the electric sparks starts when the abrasive grits in the rotary electrode come in contact with the workpiece surface.

Copper Alloys — Use negative polarity and expect low MRR and high electrode wear. Aluminum — Although aluminum is easy to machine, it is hard to get a good surface finish. ELECTRODE. Electrode Size. The block size of graphite is not a limiting factor when choosing a material.

The wall of the cup electrode passes through the center of the wafer to grind the whole surface. Before the experiment, the end face of the cup electrode is leveled by servo feeding the cup electrode to a tungsten-copper alloy dressing electrode at a rotation speed of 50 rpm.
