It is determined by the maximum load in pounds per square inch divided by the cross-sectional area of the wire. Complex shapes that would otherwise be difficult to produce with conventional cutting tools, Extremely hard material to very close tolerances. Wire EDM machining (also known as \"spark EDM\") works by creating an electrical discharge between the wire or electrode, & the workpiece. More background information about wire-cut EDM, die-sink EDM and EDM drilling. Much like the carpenter’s fretsaw, wire EDM can cut in all directions. Wire EDM is a metalworking technology and an unconventional process that works on components that are resistant to conventional machining processes, thousands of sparks are discharged onto metal work pieces for cutting, but the necessary conditions are that these parts must be electrically conductive, usually are metal materials such as steel, titanium, alloy, and brass. A heavy coating of pure zinc is applied to the outer surface (18-35μm) of a copper or brass core. Steel core wire is an option when attempting extremely tall parts, parts requiring good straightness, and where poor flushing conditions exist. This wire consists of a thin (approximately 5 micron) zinc coating over a core which is one of the standard EDM brass alloys. It is a very precise method for the right applications, such as for 2-axis cutting of small parts with tight tolerances at high volumes. For cutting of different types of metal wires, the rendered CNC wire cut EDM machine is used. The typical wire diameter is 0.25mm in diameter and comes in spools that are about 10 miles long, the cut is larger than the diameter of the wire, since the wire does not actually touch the work piece and “cutting” occurs due to the spark from the wire to the workpiece. The first wire used for wire EDM was copper. Standard wire machines use a continuous piece of brass wire to cut hard materials. Cutouts and be created by threading the wire through a previously drilled hole. Wire electrical discharge machining shapes metal materials with an electrically-charged strand of brass wire. The combination of break-resistance with the performance of 50/50 brass can make this wire a problem solver for difficult applications. Wire EDM - Recommended Materials. Eventually, the dielectric material will reach a point where electrical breakdown occurs and sparks will fly across the gap between the wire and the workpiece, thus causing both to be eroded by the current. Part Prototypes. Many machines … Available in small diameters (.001”-.002”), tungsten wire has the highest tensile strength of all EDM wires. Economical cutting of tool steels and most metals is possible with plain brass wire. Electro-galvanization is the most precise method of application, depositing pure zinc, atom by atom onto the body of the wire, insuring uniform thickness and surface uniformity. Subsequent passes will retrace the cut path at a lower speed and removing less material but as a result improving the surface quality and bringing the workpiece to specification. Wire cutting Wire EDM machine uses a metallic wire (electrode) to cut a programmed contour in a workpiece. The hardness or temper of a wire refers to the wire’s ductility, or its ability to undergo elongation. Use in wire-cutting EDM machines. Obversely, wires with high elongation can taper-cut to 45° but with much reduced threading relaibility. Diffusion-annealed wires are available in tensile strengths from 62,000-128,000psi and appear yellowbrown to brown in color. Their easy operation, low maintenance, high performance and less power consumption, makes the CNC wire cut 3. JavaScript seems to be disabled in your browser. Wire EDM is a method to cut conductive materials with a thin electrode, a wire.There is no physical contact between the part that is being machined and the wire. The spark gap is small enough already and we don’t need “chunks of stuff” floating around in it. Electrical discharge machining, 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. Because of it’s high working temperatures, the EDM craters left on the wire’s surface are very small compared to those left on a brass-based wire and therefore will not flush as efficiently. The moving wire erodes any conductive material that is within .0005” of its path, while the deionized water cools and flushes away debris from the cut. In wire EDM, … The term hardness is often mistaken for tensile strength. but because moly wire has very high melting and vaporization temperatures, 4,757°F (2,625°C) and 10,040°F (5,560°C) respectively, it is a reletively poor electrode material. On closed-guide machines, a hard wire will thread better than a softer wire, but a soft wire will taper-cut better. This is the measure of a material’s ability to carry electrical current. The wire is used as it can be continuously spooled so that the electrode does not become too eroded. A thin single-strand wire electrode is placed over the material on a CNC-controlled robotic guidance system. In addition to metals, other conductive materials such as graphite, diamond and metal alloys can be machined using wire cut EDM. Some of the advantages of EDM include machining of: Providing precision manufacturing through strategic partnerships. An electric current is run through the wire, creating an electrical spark of intense heat (8000-12000°C). Even though melting produces chips, lowtemp electrode alloys (zinc-coated) will produce larger craters on the wire surface to carry more water and contaminants away from the gap, aiding flushing. In EDM, the higher the conductivity of the wire, the more power can be delivered to the workpiece. Modern Wire EDM machines often include multiple heads to cut more than one piece and automatic wire threading. The EDM wire electrode is moved close the workpiece, which is then gradually eroded by the electrical discharge. In special cases, typically in medical and military applications, there can be no copper or zinc contamination of the wirecut surface. Wire cut EDM machine is able to machine material, with high hardness, high strength, high fragility and high tenacity, which is not easy to be or can’t be machined by conventional method, even some semi-conductive materials are also can be processed by wire cut EDM machine. Wire cut electrical discharge machining (WEDM), is used to cut hardened metal plates as thick as 300 mm that are typically difficult to machine in any other way. The dielectric fluid in this case—usually deionized water—is flushed through the cut as it proceeds, again serving to carry off particles and control the sparks. Wire EDM Cutting method in which an electrically charged wire is fed through a workpiece creating an electric discharge that cuts a contour in its horizontal plane. Undergoing annealing in a special furnace diffuses the pure zinc coating into a mixture of nearly 50% brass and 50% zinc (actually, zinc content is approximately 45-47%), which is higher than the 40% threshold which was the previous manufacturing limitation. Wire EDM Wire EDM machining on material up to 16 inches thick. Brass wires for EDM are typically an alloy between 63/37 (American and European) to 65/35 (Asian), Cu/Zn ratio. Available in hardness (elongation) in ranges from <2% to over 30%. Wire-edm is, usually, slower than other methods. Also known as spark machining, electrical discharge machining (EDM) uses electrical current to erode a metal workpiece to a desired shape. It is also used when the final piece needs to have low stress, Wire EDM has low cutting force for material removal and little change in the mechanical properties is usually seen. Most wire EDM machines hold the wire vertically and move the workpiece in x and y. The EDM wire cutting machining services process utilizes an electrical current discharge between two electrodes, which are the tool and the workpiece. Innovative machining technologies such as wire cut – also know as wire erosion or wire EDM, become ever more in demand, especially as wire cut machining automation and accuracy improves to new levels of performance. Brass wires are a good, all-around utility wire that can be used by most modern machines.

In Wire EDM cutting, the material to be cut is submerged in a dielectric cutting fluid, usually deionized water. These wires are suited for fast cutting of tall workpieces, volume production and in poor flushing conditions. All Rights Reserved. Regardless of the name, the process uses electrical discharges traveling along a brass or zinc-coated brass wire to very accurately cut and simultaneously remove material from a work piece. This allows tapers to be cut into the workpiece; this is particularly useful for the production of extrusion molds. Very small work pieces where conventional cutting tools may damage the part from excess cutting tool pressure. Typically the electrode diameters range from.004″ –.012″ (.10mm –.30mm), … Among the industries that make use of components manufactured by EDM include the semiconductor industry, medical and instrumentation. This criteria eliminates all copper-family wires and forces the use of a moly or tungsten wire. For example, for mass production of pins, probes, and other small, solid metal parts with diameters under 0.020” (0.50 mm), wire EDM can deliver: 1. Wire EDM services are typically used to cut hard metals that are sometimes difficult to manipulate using other cutting methods. Sabre Cut SC-1; EDM Metallics. Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage. CNC wire EDM is performed AFTER heat treatment so that the finished dimensions are not affected. Rather, the wire is charged to a voltage very rapidly. Because of its high tensile strength, moly wire aids in maintaining excellent wall straightness and reducing the number of wire-breaks common with many small and fine brass wires. Steel-core fine-wires (.001”-.004”), have a tensile strength of 290,000psi, exceeding that of moly, but with much better cutting characteristics. Except in older machines that specify the use of copper wire, this wire is seldom recommended. Fa… This would include all metals, including steel, aluminum, brass, titanium, and alloys and super alloys of all types. It is a quicker and less precise method of coating and these wires will usually be less expensive. It is also used when the final piece needs to have low stress, Wire EDM has low cutting force for material removal and little change in the mechanical properties is usually seen. Wire EDM is best used for relatively low production volumes of items that require tight manufacturing tolerances. If the smallest diameter wire is used then the cut can be within plus or minus a micrometer. Machining of all steels, carbide, and aluminum; 15.7″ x 23.6″ table travel; We machine parts up to 16″ thick ; Wire diameters from 0.004″ to 0.012″ 4 Axis Programming; Part Prototypes Create custom part prototypes to meet your project's exact specifications. Below are listed the more common types of materials we machine using Wire EDM: Inconel : Aluminum: Vasconal 300: Tool Steels: Aluminum … Wire EDM Wire Edm Advantages Wire Edm Equipment Materials Cut Wire EDM FAQs. Sabre Cut SC-1 is a premium material offering the highest tensile strength in the Industry for brass. High-tensile wire is also good for skim cuts, aiding in part straightness and geometric accuracy. Custom Machining High Precision Wire EDM Cutting Machine Parts, EDM Wire Cutting Part, EDM Part for Metal Mold. Cutting. When using longer on times (roughing), melting will occur. Wire-cutting EDM is commonly used when low residual stresses are desired, because it does not require high cutting forces for removal of material and there is no direct contact between the work piece and wire eliminating the mechanical stresses during machining. Tensile strengths of brass wires range from 54,000-173,000psi, depending upon the composition of the alloy and it’s temper. Wire EDM is used in the manufacture of extrusion dies, blanking punches and tool fabrication. In this category, EDM wires are called soft or hard. Wire EDM is referred to in many ways: wire cutting, wire burning, and traveling wire EDM. Zinc coated wires will cut much faster and break less often than plain brass wires and are recommended for fast roughing and finishing of steels. This allows for tapers and other complex, intricate and delicate shapes to be machined. This fluid helps to cool the process and flush away the cut material. *Actual adjustments of current, servo speeds, flushing pressure, etc., are not noted here but may be necessary to realize the full potential of the troubleshooting process. The current creates sparks capable of cutting the substrate into pre-programmed designs. The Practical Application Range of Wire Cut Electrical Discharge Machining. With the wire EDM cutting process, controlled and rapidly repeating electrical charges are used to remove material from electrically conductive materials. This wire is often used in the small, (0.006 to 0.004”), and fine, (<0.004”), diameters to meet blueprint requirements of narrow kerfs and near-sharp, inside corner radii. 1. Larger diameters (.006”-.012”) have tensile strengths in the range of 116,000-145,000psi. The wire is usually made of a single strand of brass, and is held at the top and bottom by diamond guides, the guides can move in the x-y plane and the upper guide can move independently in three axes. All prices shown on this website exclude VAT. wire-cut EDM, die-sink EDM and EDM drilling. Although this wire is very expensive, cuts poorly and is hard to work with, it is sometimes the only solution to an EDM problem. It’s availability and high conductivity (100% IACS) made it a logical choice for an EDM electrode at the time, but as generators became more powerful, copper’s limited cutting speed and low tensile strength (34,000-60,000psi) quickly revealed it’s limitations. These wires are available in tensile strengths from 61,000-130,000psi and can have a pure zinc or zinc oxide coating depending upon the application. Wires with high zinc content make a better EDM electrode but EDM wire with zinc percentages approaching 40% are difficult to produce, so a special method of producing wire with a higher zinc surface has been devised. Zinc-coated wire cuts faster than uncoated wire. This is a very high strength wire with tensile strength in excess of 275,000psi. All chips have mass and therefore, will “take up room”. The result is often a reduced need for post-processing or surface treatment. The advantage of EDM is that it can cut hardened materials and exotic alloys while also providing excellent surface finishes as a bonus. As the wire is brought close the workpiece the electrical field increases as the distance squared. MWI offers a full compliment of metallic electrode materials and sizes. Wire EDM machining (Electrical Discharge Machining) is an electro thermal production process in which 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. There is no direct contact between tool and work piece. An electrical discharge (spark) is created between an electrode which is usually a wire, and the piece to be machined. As the spark jumps across the gap, material is removed from both the workpiece & the electrode. There is usually a low conductive liquid medium between the two, such as deionized water, which is continually flushed as the work progresses. Properties. Hard wire works better than soft wire in EDM machines with automatic wire threading. Machining with wire EDM. With even higher melting and vaporization temperatures than moly, 6170°F (3410°C) and 10,706 (5930°C) respectively, it is the least efficient wire electrode in regard to cutting performance. Owing to our industrial experience and knowledge of this domain, we manufacture the premium quality of CNC Wire Cut EDM Machine. V W Broaching works with a variety of materials for wire EDM machining. Fig. 4. The larger types are built for cutting workpieces as thick as 20 inches, while for drilling holes a small hole drilling EDM head can be attached, which uses a wire to erode and penetrate into the workpiece. Sorry, no can do pardner. Wire EDM (electrical discharge machining) is an accurate and effective method of producing custom parts and components from metal. It’s availability and high conductivity (100% IACS) made it a logical choice for an EDM electrode at the time, but as generators became more powerful, copper’s limited cutting speed and low tensile strength (34,000-60,000psi) quickly revealed it’s limitations. Therefore delicate sections and weak materials can be machined without any distortion. Wire EDM Wire Cut Electrical Discharge Machining is a metal working process where electrical erosion is utilized to separate material from a conductive work piece. The selection of EDM wire used to be easy as there were only a few choices; copper or brass. Hot-dipping is another method of coating the wire. Wire cut (wire erosion EDM Machining): Wire EDM Customers are demanding more from their supply-chain partners than ever before. Wire EDM uses a thin wire composed of copper or brass to conduct electrical current between an electrical source and an electrically conductive base material. As the workpiece is eroded the electrode is moved further into the piece, along a computer controlled path. High-tensile EDM wire provides better edge straightness and so is a good choice for single-pass parts and in small- and fine-diameter wires to reduce wire breakage. A hard wire will also provide the best auto-threading reliability. Typically a finished piece will go through several passes, the initial pass is relatively quick, and removes the most amount of material. Like all machining processes, EDM requires a balancing act between speed and surface finish. Coated EDM wires are wires that have had a very thin layer (2-3μm) of pure zinc applied to a brass or copper core. One of the electrodes is called the tool-electrode, or simply the tool or electrode, while the This allows it to cut very fine, very straight-walled details with sharp definition. Extrusion dies and blanking punches are very often machined by wire cutting. The “over cut” is predictable and can be programmed into the CNC work steps. All conductive materials can be discharged . In the machining area, each discharge creates a crater in the workpiece (material removal) and an impact on the tool (wear of the tool/electrode). It is the ability of the wire to resist the effects of the incredibly dynamic environment of the spark gap. There are various wire EDM machines for sale in different sizes to suit customers’ needs. Wire Electrical Discharge Machining Traveling Workpiece Wire Electrode Motions Wire Motions Wire EDM Used Primarily for Through Hole Machining. There is no true index or “rating” of fracture resistance, so fracture resistance of an EDM wire might better be described as wire toughness or resilience. Wire EDM Capabilities. Wirecutting tall parts is another application that requires good straightness and resistance to wire breaks. mechanical stresses during machining. Wire electrical discharge machining (WEDM) uses a metallic wire to cut or shape a workpiece, often a conductive material, with a thin electrode wire that follows a precisely programmed path. Brass wires are usually a shiny brass color. This type of wire has a core of carbon steel for high strength and fracture resistance and is clad with a thick layer of zinc-rich, diffusion-annealed brass to provide good cutting qualities. Excep… In Wire Electrical Discharge Machining (WEDMing), or Wire-Cut EDM, a thin single-strand metal wire is fed through the work piece, typically occurring while in a submerged tank of dielectric fluid or deionized water. Tensile strength is the maximum load-bearing capability given to a material based upon its ability to resist stretching and breaking. Brass wires with a dull, matte finish or with spots or discoloration are indications of oxidation or contamination. We have economy and utility-grade wires, wires for speed, wires for carbide and PCD’s, wires for tapering, and fine-wire machining. Note: Use of moly wire must be application-specific because of its high cost, reduced threadability and slow machining times. Contact us today for a quote on your high quality, precision manufacturing need. They can be used against a wide range of materials including tool steels, aluminum and graphite. A low melting/vaporization temperature of the wire will prove the best for flushability. Description. In these machines, this wire must be used to wire-cut all materials simply because there is no other alternative. Since higher conductivity is more efficient, increased cutting speeds are the usual results. © 2013-2021 Novotec BV. Like moly wire, tungsten wire is also used on applications that must be free from copper or zinc in the cut surfaces. Wires with low percentages of elongation will thread reliably but are limited in tapering ability. However, manufacturing difficulties arise when the volume of zinc approaches 40% and its crystalline structure changes to a gamma phase, causing the wire to become very brittle and difficult to draw. The highest precision of EDM electrical discharge machining can reach +/— 0.005mm surface roughness up to mirror surface. Today, there are more electrode choices for wire EDM than there are for sinkers. EDM (electrical discharge machining) is a non traditional metal machining process that uses spark erosion to remove material from the workpiece. (Image courtesy of Makino.) Consequently, moly and tungsten wires, with high melt/vaporization temperatures cut slowly and flush poorly, but are satisfactory for skim cuts where speed is not an issue but part straightness and crisp geometry is. Why choose graphite for EDM applications? Highly repeatable lengths without end deformation, distortion, or delamination 2. Pure zinc coatings will have a shiny, silver color while a zinc-oxide coating will appear dull gray. Don't limit the response to what exisiting machines can do based on their size/geometry, I really just want to know what becomes the limiting factor in how much material can be cut and what that limit is. 54,000-173,000Psi, depending upon the application are very often machined by wire cutting is.
