What is Wire EDM?

Wire EDM differs slightly from conventional EDM – the spark produced in Wire EDM always takes place in deionized water (the dielectric used for Wire EDM processes). Deionized water is used in Wire EDM because of its low viscosity, high cooling and material removal rate, and because deionized water is not a fire hazard. In Wire EDM cutting, a metallic wire (typically made of brass or stratified copper) between 0.1 and 0.3 mm in diameter is used to cut or rough/skim the part being machined. The wire used never comes into physical contact with the component being machined. The process used and the specifics of that process depend on the accuracy and surface finish required. DEYUCNC’ experienced EDM machinists have years, and in some cases, decades of experience properly setting up, programming and finishing EDM work from start to completion.

Ideal for machining delicate and complex parts, Wire EDM machines can be accurate to +/-1 micron and produce virtually no burrs (eliminating or greatly reducing the finished work required). Wire EDM machines are capable of machining workpieces up to 16” thick.

How Does Wire EDM Work?

As with all EDM machining, measured voltages between two electrodes are required to produce a current of electricity. These electrodes create a spark, generating temperatures of over 14,000°F to vaporize and erode the material being machined. EDM machining service With wire EDM, voltage is sent through the wire and a current path is established between the work piece and the wire, which serve as the two electrodes. A precise servo motor ensures constant gap between the wire and the piece. If the wire were to touch the work piece, a short circuit would occur, stopping the process. In some ways, it is helpful to compare the wire EDM cutting action to that of a band saw, except the teeth of the band saw are replaced with the spark, which jumps from the wire to the work piece nearly a million times per second to erode the material. Eroded materials shed from the work piece are no larger than specks of dust. Like a band saw, the thin wire is spooled and constantly fed between two computer assisted guides. This constant spooling action provides a fresh cutting surface throughout the wire cutting process. Because the cutting action produces constant erosion of both electrodes, long lengths of wire must be used – around 11 miles long (19 km) – and spools can weigh about 18 pounds, depending on the wire’s gauge. Once the cutting dimensions are entered into the CNC machine, the process is ready to begin. De-Ionized Water: Wire EDM Cutting Medium Pressurized and de-ionized water, or any dielectric fluid, provides resistance to the spark. This resistance helps to precisely control the level of voltage jumping from the wire to the work piece, providing a consistent cut. Unfiltered water does not work for this purpose. The minerals present in normal water act as a conductor of electricity which would mean uncontrollable cutting at lower levels of voltage. Resin tanks filter out the minerals, producing pure de-ionized water, which does not conduct electricity under normal circumstances. Only after enough voltage is applied will dielectric fluid ionize to conduct a current. Dielectric water also serves to flush any shed material from the environment, ensuring a clean cut.

EDM, also known as spark machining, is the cutting process that erode materials with an electric spark, created between an electrode and the part being machined. The electric spark produces a flow of energy between the machine and part, which will melt away the unwanted areas on the part.
Wire EDM is slightly different from traditional EDM, as the spark created in Wire EDM is always produced in deionized water. This is used in Wire EDM because it is not a fire hazard when the spark is created.
Wire EDM uses a metallic wire, typically made of brass or copper, to cut the part. Voltages have to be measured between the part and machine before cutting can occur. The process used is dependent on the accuracy and finish needed.
Industries that produce precision-dependent components requiring fast manufacturing times use Wire EDM for repeatable accuracy. These industries include medical devices, aerospace, optical equipment and more.
Some benefits of Wire EDM machining include superior consistency, simultaneous cutting, material compatibility and eliminating finishes. This machine type has one of the closest machining tolerances available today.
