Jan 01, 2002· When it comes time to decide whether to use graphite or copper electrodes in your shop, it's important to look at the big picture. According to Stu Haley, regional manager of Madison Heights, MI-based Belmont Technologies, Inc., a provider of EDM supplies, tooling, accessories and machines, "To say which electrode works best is very difficult, it is totally applications-driven.
Copper is widely used as an electrode material in EDM machining in precision mold components manufacturing plants. Many people think that graphite materials will be an alternative only when making large electrodes and when the mold processing requirements are not high or rough.
CNC surface grinding removes small amounts of material by using a high-speed abrasive wheel as the cutting tool. The grinding wheel rotates in place, while the work piece, attached to the machine table, moves in the X-, Y-, and Z-axis.
Sep 22, 2014· 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.
It is worth mentioning that sometimes graphite is impregnated with copper to form copper-graphite to take advantage of both copper and graphite. When used as EDM electrode, it offers many benefits over the standard materials. Various similarities and differences between copper electrode and graphite electrode are given below in table format.
Dec 12, 2017· This electrode is used for producing high precision electronic connectors molds by EDM, most mold require mirror surface effect. This electronic connector has high precision requirements, the ...
Apr 19, 2013· Copper Tungsten Properties & Increased Thermal Conductivity. If you've been reading the past few posts on the use of Copper Tungsten for Electrical Discharge Machining (EDM) electrodes, you know by now that the success of the process is largely influenced by both workpiece and electrode material properties.

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.
May 23, 2017· " our HQSF [High Quality Surface Finish] additive technology. Traditionally in sinker EDM, as your electrode surface became greater, it became very hard to stabilize the gap and produce a surface finish across a very large area that was consistent. You'd get hot spots, because of debris.
Don't Read This If You Use Graphite Electrodes For EDM In electrical discharge machining, graphite electrodes are the most popular for making the complicated components in injection mold making . Even though EDM copper still has a huge market in Europe and Asia, the use of EDM graphite is gaining momentum there as well.
Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a manufacturing process whereby a desired shape is obtained by using electrical discharges (sparks). Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to ...

Mar 26, 2006· Surface Grinding of copper... Easy. Use a solid metal wheel - a dead soft aluminium, and a hard and fine compound - such as a automotive valve lapping paste for a fine finnish. The hard material embeds in the aluminum, and this grinds the copper away.
Aug 01, 2014· It is not wise to EDM with varying details on the same copper electrode. This is because the higher current required to efficiently EDM larger electrode details exceeds the current allowable for the smaller detail. With copper electrodes, high current density on smaller, more intricate detail increases the electrode wear.
PDF | Electrode materials have a great impact on the productivity and quality of electrical discharge machining (EDM). This study investigated the material removal rate (MRR) and surface quality ...

An investigation was made into the combined technologies of electrical discharge machining and grinding (EDMG). A metal matrix (Cu/SiC p) electrode with a rotating device was made and employed to study the EDMG technology.It was found that 3–7 times the normal electrical discharge machining (EDM) material removal rate (MRR) could be achieved in EDMG under suitable conditions of electrode ...
May 26, 2008· The material removal rate of XW42 tool steel with copper electrode is greater than that with graphite electrode. 2. Copper electrode is suitable for roughing process, whilst graphite electrode is suitable for finishing process. Combination of both electrodes will improve machining characteristics and surface finish. 3.
