ELECTRIC DISCHARGE GRINDING ( EDG ) AND ELECTRIC DISCHARGE DIAMOND GRINDING (EDDG) ELECTRIC DISCHARGE GRINDING ELECTRICAL DISCHARGE DIAMOND GRINDING - Working Principle - Capabilities and Applications. 9. melting and vaporization) but the construction resembles the conventional grinding process. In this process only good conductors of electricity can be machined. Mechanical Assembly, Other Assembly, Milling, Other Machining, Electric Discharge. For grinders that features an electric motor, the motor rotates at a certain rpm (from 150 to 1500 RPM, it may change according to the types of grinding machine.) This is all about electrical discharge machining, principle, working, equipment’s, advantages and disadvantages with its diagram. EDM spark erosion is same as electric spark which burn a small hole in a piece of metal through witch it contacts. Electrical discharge machining (EDM) is one of the earliest non-traditional machining processes. 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. The machining of thin and fragile material is very difficult for manufacturing industries and rapid demand of requirement could not be achieved. Scribd è il più grande sito di social reading e publishing al mondo. Electric Discharge Grinding (EDG) follows the same principle of material removal (i.e. Products are exported more than 50 countries in the world. The spark produce removes metal in form of very small chips. The tool is fed up by the Servo Feed Unit which can move downward in … 2.Driling of micro holes Ruiqiang Scienece Park, Guichi High-tech Zone, Chizhou City, Anhui Province, China, WMT CNC Industrial Co., Ltd | All Rights Reserved.Design & Developed by VW Themes, Upper Roller Universal Plate Rolling Machine, Working Principle and Applications of Electrical Discharge Machining. Doc Exploded Views Of Parts Of A Grinding Machine. During electrochemical machining process, the reactions take place at the electrodes i.e. This is done by continuous supply of dielectric fluid. Expert Answer . A servomechanism is used which maintains a very small gap between the work piece and the tool. Working Principle. In EDG process, ... (rotating wheel) except during electric is known as grinding wheel. The grinding wheel used discharge [4-6]. The EDM produce a cavity slightly larger than the electrode because of overcut. It is often used to process various types of holes (a round hole, square hole, polygonal hole, special-shaped hole), curved hole, 4ql, micro-hole, etc., such as cold stamping die, wire drawing die, extrusion die, nozzle, the spinneret, etc. Instead of a stationary form electrode as used in EDM, a wheel electrode made of conductive material is used in EDG. 28. Working Principle of Electrical Discharge Machining: It consists of an electric power supply, the dielectric medium, the tool, workpiece, and servo control. The metal removed from the work piece due to erosion and evaporate ion. ADVERTISEMENTS: In this article we will discuss about the electric discharge machining (EDM):- 1. Because there are visible sparks in the discharge process, it is called electrical discharge machining. Electrical discharge machining process works on the basic principle of spark generation and metal removed by spark erosion. Wire EDM machining (Electrical Discharge Machining) is an electro thermal production process where a thin single strand metal wire, along with de-ionised water (used to conduct electricity) allows the wire to cut through metal by the use of heat from electrical sparks, while preventing rust. Considering the different aspects of their capabilities, these two processes are considered to possess maximum potential. This machining process uses electric spark to remove metal form work piece. This process is done by applying high frequency current through the electrode to work piece. The work-piece is held in a jig submerged in a dielectric fluid such as kerosene. This gas goes into environment. GRINDING . Electric discharge machining (EDM), sometimes colloquially also referred to as spark machining, spark eroding, burning, die sinking or wire erosion, is a manufacturing process whereby a desired shape is obtained using electrical discharges (sparks). WIRE ELECTRIC DISCHARGE MACHINING WORKING PRINCIPLE WIRE EDM MACHINE - Power Supply System - Dielectric System - … For example, EDM is typically slower than other machining methods, but it … This fluid also works as coolant medium.
