The wire EDM machine is capable of cutting a metal thickness of about 0.004 inches. During the machining, the wire is … Looks like you’ve clipped this slide to already. It was introduced in the late 1960s', and has revolutionized the tool and die, mold, and metalworking industries. Wire electrical discharge machining (EDM) is a process of metal machining in which a tool discharges thousands of sparks to a metal workpiece. The wire, which is constantly fed from a spool, is held between upper and lower diamond guides. The wire cut EDM uses a very thin wire 0.02 to 0.3 mm in diameter as an electrode and machines a workpiece with electrical discharge like a bandsaw by moving either the workpiece or wire . A wire drive system constantly presents fresh wire to the work so electrode wear is not a problem. Wire Erosion. 2. 4. The process is particularly useful in cutting fine details in pre-hardened stamping and blanking dies. Saving you money, while keeping your machines running is important to you, therefore, it is important to us. Find items by using the following search options. 3. For more information on an item, contact the seller directly. The tiles are produced from beryllium blocks by electrospark discharge cutting on wire-EDM machines. Process Fig. Used to cut plates as thick as 300 mm and to make punches, tools, and dies from hard metals that are difficult to machine with other methods. (b) A computer-controlled wire EDM machine. Wire EDM produces durable firearm components quickly and accurately from a variety of alloys, making it the ideal manufacturing option for firearm production. Rapid DC electrical pulses are generated between the wire electrode and the workpiece, using a dielectric shield between the two of deionised pure water. Wire EDM is also known as: wire-cut EDM, wire cutting, edm cutting, wire burning, wire erosion, and ‘cheese-cutter’ EDM. Ali Gohar 13-MT-50 Order By: Title Data Added Price File Size Downloads . In this process, a thin metallic wire is fed on-to the work piece, which is submerged in a tank of dielectric fluid such as deionized water. Hi guys, I recommend you one special molybdenum wire cut EDM machine.It is very popular in china, because of very cheap price compare with like Sodick brass wire cut EDM. 2. This is a global marketplace for buyers and sellers of used, surplus or refurbished FANUC WIRE EDM. Small hole drilling On wire-cut EDM machines, small hole drilling EDM is used to make a through hole in a workpiece in through which to thread the wire for the wire-cut EDM operation. 1. erosion of the metal utilizing the phenomenon of spark discharge that is the very same as in conventional EDM . Muhammad Shaban 13-MT-03 EDM is also a non-contact machining method and does not exert cutting forces on the part, therefore it works particularly well for delicate structures. The workpiece must be electrically conductive. Electro-thermal separation processes are available as an alternative to cutting processes when a low mechanical strain is required to manufacture highly complex geometries. TOPIC : Wire Cut EDM. Wire erosion is a precision controlled, highly accurate ( 5 microns ), stress free metal removal process. Typical wire diameters range from .002 to .013 inches. Small hole drilling On wire-cut EDM machines, small hole drilling EDM is used to make a through hole in a workpiece in through which to thread the wire for the wire-cut EDM operation. ESPRIT supports indexing, turning, and simultaneous cutting for all EDM machines that support rotary motion. It is probably the most exciting and diversified machine tool developed for this industry in the last fifty years, and has numerous advantages to offer. Blohm Planomat HP Series CNC Surface & Profile Grinders - Latest Brochure fro... No public clipboards found for this slide. You can change your ad preferences anytime. Image credit: Pixel B/Shutterstock.com. Wire EDM Machining is an electro thermal production process where a thin single-strand metal wire in conjunction with de-ionized water (used to conduct electricity) allows the wire to cut through metal by the use of heat from electrical sparks. 1 shows schematically the basic working principle of EDM process. Local extraction systems. Wire cut EDM (or WCEDM) discharges the electrified current by means of a taut thin wire, which acts as the cathode and is guided alongside the desired cutting path, or kerf. To better understand the wire EDM process, visualize the wire EDM machine as a super precision band saw with accuracies capable up to +/-0.001 (0.0025mm), and under certain circumstances even closer. The wire moves in a carefully controlled pattern, roughly analogous to a woodworker’s scroll saw, causing sparking to occur between the wire and the workpiece.  Name Roll no Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks).
