The spark generated by this process produces heat, which remove metal by erosion and evaporation. Advantages of Small-Hole Wire EDM. (Vol ) Tj 1 0 0 1 0 22 cm I am here to ask the key advantages of micro-EDM over LASER and Reverse Micro-EDM over LIGA in terms of process feasibility over materials, machined feature quality and economy. 0000002427 00000 n Additionally, EDM can create surface finishes as smooth as 5 RMS or around 4 micro-inches Ra. The main advantages of the micro-EDM method are its low set-up cost, high accuracy and large design freedom. The EDM drilling station bores holes by using an electrode that rotates within a chuck that has a constant flow of distilled or deionized water. 0000002948 00000 n At TEKNIKER R+D activities are being undertaken, researching into and enhancing the current process of electrical discharge machining, endeavouring to improve results and making it a more environmentally sustainable process, opening the market to a new materials and applications. In spite of many studies on fast EDM hole drilling, the research on making of small-size holes on aerospace alloys is limited. (2010, ) Tj The process is also applied to producing holes in turbine blades for the aerospace industry [2]. 0000507943 00000 n Advantages. (17 ) Tj 0000509953 00000 n 0000535389 00000 n “Since the tool does not touch the workpiece, there are no cutting forces generated; therefore, very fragile parts can be machined” . (II, ) Tj 0000561251 00000 n These advantages of micro-EDM have made it the most potential candidate in micro-machining domain for achieving micro features of high-aspect-ratio. At ADVANTAGE EDM, our large number of the latest generation Wire Electrical Discharge Machines, combined with our new large capacity Wire EDM (with a travel of 14.6" x 20.5" x 18" high) and our new large tapering Wire EDM (with a tapering capacity of 45 degrees), we are more than equipped to handle your high volume production quantities. 0000547350 00000 n 0000528308 00000 n 0000511682 00000 n 17.5 0 Td Cuts extremely hard, challenging and exotic materials to very close tolerances for high precision mechanical components. 33.062 0 Td In other words, there is an electric current imparted on the rod, a spark gap where the material is removed, water flush to remove EDM debris and wear rate of the rod. Small hole drilling times vary depending on material purity, flush rate, and rod diameter. Moreover, the range of processable materials is almost unlimited because the sole condition is their electrical conductivity. Micromarketing and concentrated marketing allow companies to become granular. In the precise manufacturing of high-quality products, new prospects open up thanks to micro EDM. The shape and also the hardness of the materials being used make EDM ideal. By using this instrument it is possible to find out the coordinates of a reflector adjusting the cross hair of the instrument and at the same time measuring the vertical angles, horizontal angles, and slope distances. Although both processes are competitive for certain geometries, each of both processes has its specific advantages. For organisations that need to buy-in design expertise, Micro Engineering Solutions, which is based in the USA, offers design as well as manufacturing and assembly services. Doing so will help you avoid accuracy errors and other problems. Micro-EDM is a newly developed method to produce micro-parts which in the range of 50 µm -100 µm. The use of micro-EDM has many advantages in micro-parts, and the main advantage is that it can machine complex shapes into any conductive material with very low forces. 0000530155 00000 n Electrical Discharge Machining (EDM) and Electrochemical Machining (ECM) offer a better alternative or sometimes the only alternative in generating accurate 3-D complex shaped macro, micro and nano features and components of difficult–to-machine materials. 0000512589 00000 n 0000553946 00000 n Dielectric Fluid For Wire EDM: What Is It and What Does It Do? EDM works by eroding material in the path of electrical discharges that form an arc between an electrode tool and the work piece. These small features are achieved with electrodes that are also very small in size. The Major Advantages of Creating Prototypes Using Wire EDM, Wire EDM for Precise Aerospace Components Manufacturing, Wire EDM Metal Cutting For High Quality Finishing. TEKNIKER develops electrical discharge machining solutions using die-sink EDM and wire electrical discharge machining. We offer special capabilities in small-hole wire EDM (Micro EDM).
