Electrical Discharge Machining Can Create Custom Parts

Posted on

If you are a custom motorcycle or car builder, there are going to be a lot of times when you aren't going to be able to find the exact part that you need to have so that you can make your design come to life. That means that you are going to need to have that part machined. There are a lot of different kinds of machining processes that you can take advantage of. One of them is EDM. 


EDM stands for electrical discharge machining. It is also called spark erosion. That's because the process is done with electrical sparks that remove the material from the piece that is being worked. The way that it works is that there is a special tool or wire electrode on one side and the workpiece on the other side. The workpiece is then connected to a power source. When the tool or electrode reaches the workpiece, the material in that area is removed. The workpiece may also be set in a dielectric fluid that will circulate around the piece and take away any of the material. There are two basic kinds of EDM. 

Wire EDM

Wire electrical discharge machining is generally used to cut out shapes from the material or to cut out shapes out of already existing parts. For example, if you have a particular logo that you want to have cut into a disk or gear, wire EDM would be good for that. Since most of these machines and processes are CNC machines, you will be able to get the exact shape and size that you want, and it will be endlessly repeatable. 

Sinker EDM

Sinker EDM is also called probe or die sink EDM. That's because it uses a special tool to do its work. It does the same thing as wire electrical discharge machining, but it can also do things like create cavities or holes into any particular shape. For example, if you need to have a custom cap for something, this method will be able to make the shape you need, and then create cavities underneath it to create the space to screw it on to wherever it's going. 

EDM is used in a lot of industries, but if you create custom motorcycles or cars, EDM can be a lifesaver for you and will be able to let you get the pieces that you need in order for your creation to come to life. For more information, reach out to EDM manufacturing services in your area.
