Frequently Asked Questions About Electric Discharge Machining
The following are some frequently asked questions about electric discharge machining:
What is electric discharge machining? Electric discharge machining is using a flow of electricity, visible as an electrical spark, to shape melt. The heat of the flow of electricity used for EDM can reach thousands of degrees, so it will be able to melt virtually any material. The special equipment used for EDM carefully controls the flow of electricity. This keeps the heat at the surface of the metal and ensures that the electrode affects only the desired portion of the work piece. A dielectric liquid, like specially charged water, is typically used to wash away the bits that have been drilled away and to keep the electrical spark under control.
What is electrical discharge machining used for? Electrical discharge machining can be used to cut and shape many different things. EDM is often used to cut work piece, but it can also be used to make holes and slits in objects. EDM is often used for industrial work because it can cut and shape metal without the need for forceful machinery.
What are the different kinds of electric discharge machining? There is sinker EDM and wire EDM. Sinker EDM involves submerging the electrode and the work piece in a dielectric liquid, like water or oil. When the electrode is moved closer to the work piece, electrical energy builds up and creates sparks. These sparks jump back and forth between the work piece and the electrode. The surface temperature of the work piece increases, burning away excess metal. Wire EDM also involves submerging the work piece in a dielectric liquid, like water or oil. Wire EDM, however, involves a wire, usually made of brass, being run through the work piece. Electrical energy builds up between the wire and the work piece, which results in an increased temperature and, ultimately, disintegration of the portion of the work piece that is located directly around the wire.
Electrical discharge machining (EDM) involves machinery that cuts, contours, and transforms a variety of metals. The process can include wires, tools, high performance machines, equipment, volts, sparks, protection and safety systems, circuits, relays, and switches. There are different types of EDM processes, such as sink, cavity, ram-type, plunge-type, or conventional. EDM is desirable because it can cut odd shapes and tough angles that you just can't cut by hand or by traditional machinery. Some electrical discharge machining wholesale companies sell machines for one type of purpose, while others sell a wide variety of machines for a wide range of products and services, such as coins, die cuts, drilling, lathes, forging, shearing, band saws, and punching machines. Electrical discharge machining wholesalers sell such machinery, equipment, and supplies at a bulk discount. You can either buy new, used, or second hand machinery from electrical discharge machining wholesalers. This can come in handy if you need many machines at one time, as wholesalers typically sell bulk quantities at a significant discount. You can even purchase parts and accessories from electrical discharge machining wholesale companies. Look up electrical discharge machining wholesalers in your local phone book or online directory listings. Consider whether you want new, used, or second hand machinery items and target your search accordingly. Take into account your budget and stick to it. Go online to research the latest in state-of-the-art new machinery, processes, tools, wires, and machines. You can also view photos, product reviews, sales, bulk discounts, detailed product descriptions, shipping and handling information, new and used products, industry news, repair services, and local wholesale dealers near you. Ask others in your business which wholesalers they use for their electrical discharge machining needs.
