Material Compatibility: Wire EDM can make accurate cuts on a wide range of materials. What is Wire EDM? EDM comes in two basic types: wire and probe (die sinker). Introduction Wire electrical discharge machining (WEDM) is capable of producing intricate parts with high dimensional accuracy and excellent surface finish without the need for post-processing. Making the right choice requires an in-depth understanding of your application, its parameters, and the product’s end use. Learn the difference and how to measure them here. Advantages of EDM Machining . How does laser cutting compare with other precision metal cutting methods? This is considered to be one of the most basic disadvantages of earlier technology available with the help of wire EDM machine, whether the material is hard or brittle without any impact you can get available with the desired shape. At the same time, the impact leads to the wear of the tool. Many EDM machine electrodes can rotate about two-three axis allowing for cutting of internal cavities. Modern EDM machines with AWT (automatic wire threading) and CNC capability can be programmed to work “lights out,” to help mitigate the slow cutting speed. We supply high-precision prototypes, medium-volume runs, and long-term, high-volume EDM … At ADVANTAGE EDM, our large number of the latest generation Wire Electrical Discharge Machines, combined with our new large capacity Wire EDM (with a travel of 14.6" x 20.5" x 18" high) and our new large tapering Wire EDM (with a tapering capacity of 45 degrees), we are more than equipped to handle your high volume production quantities. of tight tolerance, small metal parts is at the core of our business.
