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. Theme by Prower & Wopus. Take discharge as an example: The wire will be energize and create electrical spark between the wire cut cnc machine and workpiece. 5 Axis CNC EDM Wire Cut Machine is 5 axis cnc control middle speed machine, with high precision. T… If there is a load, the wire edm will moving slowly towards the electrical conductive workpiece. investigated the machining of HSS M2 material in wire edm using Response Surface Methodology (RSM) coupled with Grey Relation … … Extrusion dies or nozzles and horns can be cut with constantly changing tapers. To start machining it is first necessary to drill a hole in the work piece or start from the edge.  A thin wire of brass, tungsten or copper is used as an electrode.  Deionized water is used as the dielectric. In the early days, it was difficult to manufacture parts with fine shapes and tight tolerances using conventional machining techniques, but nowadays, parts with tight tolerances can be achieved by the electric discharge cutting process using wire cutting.  Takes shape opposite to that of cutting tool  Electrode (cutting tool) made from electrically conductive material  Dielectric fluid surrounds both tool and work  Servo mechanism gives gap.005 to.001 in. The working principle of electrical discharge machining is: between the machine tool and the workpiece (positive and negative electrodes), a method of machining to remove excess material by electrical corrosion during electrical discharge to achieve the size and shape quality of the remaining workpiece. The tool and workpiece must be electrically conductive and a small gap is maintained in between them. It can also cut various sample plate, magnetic steel, Silicon Steel Sheet, semi-conductive material or precious metal. A metallic wire (usually brass or copper) has high voltage electrical discharges passed through it that allows it to cut through the entire thickness of the material.

Extrusion dies and blanking punches are very often machined by wire cutting. Sinker EDM, also known as die sink EDM, uses pre-shaped electrodes that are “sunk” into the base material to create the desired component. CNC wire cut EDM machine puts impulse voltage between electrode wire and workpiece through impulse source, controlled by servo system, to get a certain gap, and realize impulse discharging in the working liquid between electrode wire and workpiece. In Electrical discharge machining; a potential difference is applied across the tool and w/p in pulse form. What is the principle of EDM? Applicable objects of WEDM machine: Wire cutting technology and wire cutting machine tools are widely used in various industries. WEDM Machining Working Principle Wire Cut Machine Working Principle picture from Lampard (Jiangshu) Machinery Co., Ltd. view photo of Wire Cut Machine Working Principle, Wire Cutting Machine Cost, Wire Cutting Machine Manufacturers.Contact China Suppliers for More Products and Price. Because the wire never touches the work piece, there are no cutting forces, so you can cut thin stock, fine ribs, or very delicate forms. CNC wire cut EDM machine puts impulse voltage between electrode wire and workpiece through impulse source, controlled by servo system, to get a certain gap, and realize impulse discharging in the working liquid between electrode wire and workpiece. Uses of a Sinker EDM Machine On the machining area, each Wire EDM has … Find here CNC Wire Cut EDM Machine, CNC Wire Cut EDM Machinery manufacturers, suppliers & exporters in India. Wire EDM machining (also known as \"spark EDM\") works by creating an electrical discharge between the wire or electrode, & the workpiece. Cutting is always through the entire work piece. As the spark jumps across the gap, material is then removed from the work piece and the electrode. EDM process involves a controlled erosion of electrically conductive … The procedure should happen in the liquid with insulate capacity, for example saponification and deionized water, the liquid could act as medium of discharging channel and provide cooling and flushing. The principle benefits of EDM—its excellent surface finish, minimal heat-affected zone (HAZ) and ability to cut hardened materials and exotic alloys—make it ideal for certain hole-making applications. CNC wire cut also known as cnc wire cut edm which is working base on electro sparking principle. The tool and workpiece is immersed in a dielectric medium (kerosene or deionized water). 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. Application of wire cut EDM machining 2011-11-04 Wire cut EDM machining is mainly used to process various punch tie, plastic mold, Powder metallurgy mold and etc, which have 2D and 3D faces combined, or components. Principle of wire cut EDM. Although both methods operate using electrical current discharge, they operate under slightly different principles. EDM wire cutting uses a metallic wire to cut a programmed contour in a work piece.  With wire edm you can basically cut out any design. Electrical discharge machining (EDM), also known as spark machining, uses either an electrode for EDM sinking or a brass wire for wire EDM. 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. As the potential difference is applied, electrons from the tool start to move towards the workpiece. Within this range, not only impulse power can break through insulating liquid to create spark discharging, but also the eroded workpiece can be flushed away after discharging process. EDM spark erosion is same as electric spark which burn a small hole in a piece of metal through witch it contacts. On wire-cut EDM machines, small hole drilling EDM is used to make a through hole in a workpiece through which to thread the wire for the wire-cut EDM operation. Kashif Ishfaq et al. between work and tool  Direct current of low voltage. Electrical discharge machining process works on the basic principle of spark generation and metal removed by spark erosion. Wire electrical discharge machining (WEDM) is an advanced thermal machining process capable of accurately machining parts with complicated shapes, especially for the parts that are very difficult to be machined by traditional machining processes. Wire EDM Because the wire is so fine, you can cut small-radius inside corners or even narrow slots. Wire EDM is capable of holding tolerances as tight as +/-0.0001”.Wire EDM provides a solution to the problems encountered when trying to machine materials that are normally difficult to work with, such as hardened steel, aerospace-grade titanium, high-alloy steel, tungsten carbide, Inconel, and even certain conductive ceramics.
