Electrical Discharge Machining (EDM) is a controlled metal-removal process, having two electrodes (one being the work piece) separated by a dielectric liquid that is used to remove metal by means of electric spark erosion. The electric spark is used as a cutting tool to cut the work piece to produce the finished part of desired shape. This is followed by a pulsating electric charge of high frequency, which removes tiny pieces of metal from the work piece at a controlled rate. Read this post to get insight on why electrical discharge machining process is gaining prominence in many industries.
Advantages of Electrical Discharge Machining
EDM process is widely used in production industries and various other places. Below are some reasons.
o Lower Costs: EDM helps cut exotic and high precision material components accurately at lower costs. It can be applied to all electrically conducting metals. Complex die sections and various molds can be produced accurately and precisely at a very lower cost in comparison to conventional drilling/milling machines.
o Good Surface Finish: The machine is designed in such a way that the delicate sections and weak materials can be machined without any distortion, without having any direct contact between tool and work piece. Very limited polishing is needed post the completion of the process. Fragile and other work pieces can also be machined via EDM, giving them a good finish.
o Create Complex Shapes: For cutting small work pieces or creating any complex shape electrical discharge machining is the best option, in comparison to the conventional cutting tools. Thus, all complicated shapes can be machined in limited time. Also, thin fragile sections like webs or fins can be easily machined out with high precision.
o Creating Fine Holes: In order to create fines holes, EDM is a viable tool since it allows creation of holes having precise width. Hence, in order to utilize this EDM, the need of drilling machine and electrode tubes becomes important. Also, no mechanical stress is observed between the work pieces and tool as both of them are not in contact. This allows creation of small holes.
Electronic discharge machining has been common in many industries, as it helps achieve the desired shape. If you are looking to avail EDM services from an expert, you can rely on industrial expert like China Manufacturing Parts Inc.
