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 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 handwork after
When more than one type of electrode is suitable, we can direct you to the material or grade that offers the best balance of performances and cost. Copper Tungsten EDM Electrodes. Producing Copper Tungsten EDM Electrodes is a Saturn specialty.
At my shop we surface grind a lot of brass and aluminum I am curious if anyone has any ideas on a better way to hold this down on the surface grinding table. usually i have to make a plate of steel to fit inside the brass rings so it will stop it from spinning and moving around the table.
Saturn Industries specializes in graphite CNC Surface Grinding Services. We offer all major grades and manufactured graphite including copper graphite. We offer a full range of surface grinding services such as Regrinding, Precision Form and Flat Grinding holding tolerances up to .0001.
With certain combinations of electrode and workpiece material, under special operating conditions, nowear EDM occurs, in which the wear ratio is lt0.01. The most common combination for nowear operation is a copper or graphite electrode and a steel workpiece. Materials Any electrically conducting material, irrespective of hardness.
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.
Why bother with EDM copper, when graphite is so much easier to machine and, in many cases, performs better The fact that you find copper electrodes in nearly every EDM department shows that it is important in injection mold making.. The use of EDM copper electrodes goes back to the first days of electrical discharge machining, before graphite even entered the picture.
When it comes time to decide whether to use graphite or copper electrodes in your shop, it39s important to look at the big picture. According to Stu Haley, regional manager of Madison Heights, MIbased Belmont Technologies, Inc., a provider of EDM supplies, tooling, accessories and machines, 34To say which electrode works best is very difficult, it is totally applicationsdriven.
Complete Graphite and Electrode Machining facility. Design andor build special EDM electrodes amp tooling. Research andor development of products for use in EDM. Filtration Systems for Wire, Sinkers, and Small Hole EDMs. EDM Consulting Engineering design amp build of Turnkey applications
Grinding. Surface grinding Standard surface grinders can be used with graphite, but the wheels must be kept sharp. The most common grinding wheel used is a green wheel, composed of 60 grit silicon carbide Norton, Carborundum, Cincinnati, or equivalent tools, medium grade, medium open structure, vitreous bond.
In this study, a multiEDM grinding process is adapted to fabricate microelectrodes. Equipments such as a wire EDM machine and a traditional CNCEDM machine are used for machining microelectrodes. Rod electrodes of copper with diameter 3.0 mm were cut to be 0.15 mm on wireEDM machine at first step.
Tooling Systems EDM Tooling Manufacturer. using large electrodes if not needed. The SquareOne 31mm Holder ready to accept a large copper graphite blank using the 5mm dowels Small electrode blanks can be mounted using a single screw on center All precision grinding is done on our 130,000 Wasino CNC contouring surface grinder.
EDM is a thermoelectric process which erodes material from the work piece by a series of discrete sparks between it and the electrode. Conventional EDM, shown in Figure 1, utilizes a copper or graphite electrode configured like the cavity desired in the work piece. Machining speeds are determined by the area

Brass and copper are in many ways very similar. They are available in the same range of sizes and internal channel configurations, and are both the cheapest electrode materials. Despite these many similarities, brass and copper have one main differencethe disintegration rate of copper is lower than that of brass.
Sodick supports every aspect of manufacturing from product design by CADCAM systems to molds or parts processing using Electrical Discharge Machines or Machining Center, surface finishing by electron beam PIKA Surface Processing Machine and molding by Injection Molding Machines or Press Center.
Our electrode materials expertise is in tungsten, molybdenum, and their alloys, including copper tungsten and silver tungsten as well as carbide compositions and heavy metal electrodes. Our electrodes are used in highspeed, large volume automated resistance spot welding manufacturing environments and are also excellent for die sinker EDM
