What is the wire erosion?
While many forms of erosion are considered harmful, the erosion of the wire is actually very different. Wire erosion or more precisely - machining of electrical discharge (EDM) - refers to the machine process where electric sparks are used for metal cutting. In some cases, cutting, milling or grinding (among other things) is sufficient for cutting, size or shaping a piece of metal. In other cases, for example, when working with hard metals such as hardened steel or carbide, EDM is the best or perhaps the only way to complete the work.
The wire erosion process includes electrode and workpiece. The electrode, commonly referred to as tool , leads the electricity from the power supply to which it is connected. Electricity passes through the electrode and creates sparks at the end of the electrode. These sparks essentially perform cutting or otherwise changing the shape of a metal piece, commonly referred to as workpiece . Electrodase usually moves in a vertical direction, while the workpiece moves if necessary inhorizontal position. All this transformation is done in the liquid; The purpose of this liquid is to double electricity and rinse the resulting metal dust from the work area. Because they are sparks that do all the work, some people call this process erosion sparks.
Electrode or tool erosion can be supplied in different shapes, but most often it is a thin wire. It can also be a bar of different shapes such as a circle, star or rectangle. The sparks that come at the end of the electrode do not die the workpiece. Electrodes are also worn after long use. Therefore, in the case of an electrode in the shape of a wire, the conductor is powered between two coils, so that the new wire performs cutting.
The workpiece in the erosion of the wire is usually a type of metal that has interrupted it with more common and simpler methods. As a result, hardened steel or carbide - materials that cannot be cut or drilled, such asTraditional methods - may require eroding of wire to cut. The shape of the workpiece is usually a metal block.
Wire eroding is commonly used in a production environment that works with metals. The process is used in a wide range of industries, but is primarily used in tools - tools and machines.
