  • For the Difficult Metal Machining

    Picture this: you are manufacturing a new, difficult to form, metal part. It must be exact, so you must be extra careful when cutting it. But, because it is so hard of a metal to begin with, it is hard to be careful and accomplish much of anything. Frustration starts building, soon you start working to hard, unexpected sparks fly and cause you to mess up, having to start all over. Not exactly a fun day in the office. This is why many companies have decided to go a different...

  • A Complex Industry

    What would we do without technology? There is so many ways it is making life easier. Not only are we able to carry our computers around in purses, we can easily communicate with people around the world and continue to create things that many thought would never be possible. One way in which we are able to create products in not only an easier way, but more efficient and precise way is through electric discharge machining. This is one area of industry that continues to amaze in the high precision...

  • Ram EDM, Not Your Typical Ram

    Perhaps it is because I am a history lover, but whenever I hear the word ram, I instantly revert to battering ram. Battering rams were used to break open the walls and gates of forts in ancient times. The original and simple form was a large log carried and propelled at the object with force by several people. Later, improvements were made and they could be swung from chains or ropes. However, when we are discussing ram EDM, we are talking about a very different process. Like a battering ram...

Industry Information

Ram EDM

Ram EDM, or electrical discharge machining, goes by many names including conventional EDM, sinker EDM and cavity type EDM. It produces parts through eroding material in the path of an electrical field using electrical discharges, or sparks that can generate heat anywhere from eight to twenty thousand degrees. Ram EDM is used for more complex geometries where electrodes are used to erode the desired shape into the part or assembly.

Ram EDM, or electrical discharge machining, which goes by many names including conventional EDM, sinker EDM and cavity type EDM, produces parts through eroding material in the path of an electrical field using electrical discharges, or sparks that can generate heat anywhere from eight to twenty thousand degrees. Ram EDM is used for more complex geometries where electrodes are used to erode the desired shape into the part or assembly. Industries which commonly use electrical discharge machining include aerospace, medical, tool and die, automobile and military as these applications often require high tolerances and precision components. For extremely high precision requirements, CNC EDM machines are used to guide, monitor and control the electrical discharge machining process, as well as CAD and CAM software to ensure accuracy. Ram type EDM differs from its counterpart wire EDM in terms of the type of electrode used. Consisting of an electrode and a work piece (the material being processed), the electrode is used to generate a series of sparks and is connected to the work piece through a power supply. There is no actual contact between the electrode and the work piece, but rather a conductive path that is established between the electrode and the material. Ram EDM can be applied to hard materials including stainless steel, copper, graphite, and exotic metals that would cause difficulties during conventional machining.

In addition, ram EDM is advantageous due to its ability to create complex and intricate parts with a high degree of accuracy. This process takes place in a bath of dielectric fluid, which prevents premature sparking and flushes away debris, conducts electricity between the electrode and the work piece and then flushes out the melted material. Therefore, while using this process, the work piece is not deformed from any impact as there is no direct contact between the electrode and the material, and likewise the work piece is burr-free after completion and saved from heat damage because very little material-damaging heat is generated during the procedure. Ram EDM has an advantage over wire EDM as well, because ram EDM does not cut all the way through the material, thus producing parts that wire EDM cannot. However, a disadvantage to ram EDM is the additional time and cost necessary to create electrodes. Common plunge EDM electrodes include machined graphite, copper tungsten and brass. Ram EDM is ideal for applications such as injection mold tooling, micro hole drilling, keyways, washers and scientific research apparatus.
