Effect of Electrode Material on Electrical Discharge Machining of DIN 1.2379 and DIN 1.2080 Surface
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.
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.

This paper presents the investigation on surface roughness and material removal rate (MRR) of tool steel machined with brass and copper electrode for …
Copper electroforming, together with rapid prototyping (RP) technology, provides a method for manufacturing EDM electrodes rapidly. However, the use of conventional electroformed copper electrodes is restricted because of the high electrode wear rate in EDM processes. This paper presents a study on the electroforming technique of copper/zirconium diboride (ZrB2) …
negative surface conditions do not occur after machining by EDM because of a nearly force free process. This leads to a surface which can be very well sterilised. Especially the Wire-EDM process leaves residues like copper and zinc on surfaces. These residues substantially affect the biocompatibility.
The toolmakers and grinders at our EDM machining/grinding facilities average 20+ years of experience. We maintain 100+ grinders (surface and jig) and 30+ EDM machines (wire, CNC & conventional). In metal stamping, machining & grinding, we work with materials such as carbide, stainless steel, tool-grade steel, nickel, aluminum,
EDM electrodes, with the addition of TiC, show good performance in surface finishing. This is an important characteristic as RP-sintered EDM electrodes are expected to be used as finishing electrodes. The surface roughness of most specimens is less than those machined using commercial electrodes.
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. As with all EDM services, the tool-electrode degrades with use, which requires ...

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.
For EDM electrodes, copper tungsten offers excellent electrical conductivity, DC arcing resistance, thermal conductivity, and wear resistance. ... Surface grinding services utilize precision surface grinding methods to make cubic metal parts square and parallel or the ends of metal rods perpendicular.
Fine-grain graphite electrodes are now able to deliver surface finishes similar to copper with comparable electrode wear. With the proper electrode material selection and machine parameters, graphite is able to achieve near mirror finishes without the use of a powder additive and mirror-like finishes with the additive.
Using copper electrodes upon DIN 1.2379 less microcracks appeared on the white layer surface than on DIN 1.2080. Spark erosion EDM machining exhibits less thick white layer and less micro-crack while using EDM-C 3 electrode. References 1. Jiang D, Anné G, Vleugels J, Vanmeensel K, Eeraerts W, et al.

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 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.
