Electrical wire machining or EDM in short, is a manufacturing process that utilizes electrical sparks to form a metal shape. And because of this method of operation, EDM is also known to others as the spark machining. The cutting direction of the wire which is clutched in place by an above and below guide can be set up to produce the desired shape. The required shape is further cut from the metal with the use of intensified discharges or sparks occurring between two electrodes. Cuts are made into metal where sparks originated, thus creating a desired shape to which it is automatically detached.
Wire EDM significantly governed by a wire as a tool for the electrode to cut, where it is wrapped around and the active part of the wire continually switches when in motion. According to some manufacturing companies, wire EDM is a very precise type of tool, especially if the machining requires a tolerance that is particularly in narrowed precision. EDM, according to history, has been in use since 1700 and the process has been modified and gone through some refinement for over the decades.
Today, wire EDM is considered by some manufacturer as the most cost-effective and most efficient method to perform hard and electrically conductive material. It also provides the right precision to create desired shapes more exceptional than other machining jobs. For these reasons, most manufacturing companies favored this kind of machining method due to its almost perfect accuracy that saves a lot of money. You can find below some additional benefits of using a wire EDM in a machining requirement project.
No Jolt Method
Some machining required projects, especially the hard one will need an intense processing method in machining. These will provide a more intense job for the operator to do great force in order to get the accuracy of the desired shape. Since the impact of the job requires intense methods, this will automatically produce stress that results in the wearing out of the tools. In addition, a traditional way of machining will extremely provide an inconvenience to the machinist, not like a wire EDM method that produces a best outcome to a hard, brittle and fragile material without any impacts and stresses as long as they are electrically conductive.
No Tricky Cut
With the utilization of an electrical discharge, the wire EDM will facilitate a precise cutting of the shapes through fine wire with no hassles even to the hardest type of iron or metal and even a very fragile type of material. The wire of the EDM can also create various shapes that require a fragility in nature no matter how complicated they are. The wire EDM will also cut even to the tiniest configuration that the project needs to be made. This requirement can easily be achieved through this advanced type of technology in machining without any further preconditioned requirement like heating, softening and hardening before the material is being shaped. This method will enable the machinist to fast machining operation and shortens the time to finish the projects. This will also provide more advantage in a cost-cutting needed by a customer for the said projects.
