40.835 0 Td Besides steel, other metals that can be drilled include titanium, copper, and aluminum. This is achieved by applying our many years of experience in fine wire technology and metal plating skills. 0000513573 00000 n The advantages of JPT’s wire EDM are not the only reasons why you should choose us. Q 0000002516 00000 n Micro-EDM is an efficient machining process for the fabrication of a micro-metal hole with various advantages resulting from its characteristics of non-contact and thermal process. 0000513192 00000 n 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. Author: edm Created Date: 11/3/2020 9:56:00 AM Compared to etching or deposition techniques, micro-EDM has the advantage of being able to fabricate complex three-dimensional shapes with high-aspect ratio. Fig. 154 0 obj <>stream We offer special capabilities in small-hole wire EDM (Micro EDM). 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. However, the advantage to using the plunge method over the wire method, is plunge is capable of producing 3D parts, while wire only has the capacities for 2D. The lenses are moulded in a four-cavity tool and have surface features that are between 450 and 910nm deep - though Micro Systems says it can mould smaller features if required. 0000002163 00000 n (March ) Tj Conductive alloys such as bronze, brass, and carbide, as well as superalloys like Kovar, Hastelloy®, Incoloy® and others are also viable EDM drilling candidates. In view of this advantage, micro-EDM has been widely used in the processing of micro structures [1,2]. 15 0 Td 0 Tc 0 Tw 0 Ts 100 Tz 0 Tr /Fm0 Do As material removal is mainly based on electrical energy between tool and the workpiece, there is no contact force exerted on the workpiece, adding to the advantages of the micro-EDM in very micro scale products. 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. Electrical discharge machining (EDM), as one of non-conventional material removal processes, has been widely used in the manufacture of complex features especially for difficult-to-cut materials. We have two EDM micro hole drilling stations. The advantage of using EDM instruments is the speed and accuracy in measurement. !v��X�^��0���ҙDH�����f��gu�덿ѳ��,���e��,%��u�}�}�~�9 \�| ����#�(��1\W���ݫ$x��{-�0ƻ�^�Y���wh\G�C�=ShE|-F�X�ݟӔ̲b)wt;���6�=��W7̡��uj��k�m��v��V$k�W�3�븑���[����#���z��6=�� Advantages of Electrical Discharge Machining Creates complex shapes that would otherwise be difficult to produce with conventional cutting tools. The main advantages of the micro-EDM method are its low set-up cost, high accuracy and large design freedom. Cuts extremely hard, challenging and exotic materials to very close tolerances for high precision mechanical components. Additionally, EDM can create surface finishes as smooth as 5 RMS or around 4 micro-inches Ra. But it’s always important to find a reliable and experienced partner for your projects. 0000535389 00000 n postulated an electrochemical discharge drilling (ECDD) method combining EDM and ECM in which the two processing modes elicited their effects simultaneously. CONVINCING ADVANTAGES. Micro-EDM is a newly developed method to produce micro-parts which in the range of 50 µm-100 µm. (II, ) Tj Micro-EDM is a specialized form of EDM whereby the workpieces have features as little as 10 microns (0.0004 inches). 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. This is advantageous when directionality or “lay” could influence product performance.

The shape and also the hardness of the materials being used make EDM ideal. 0000554148 00000 n EDM micro hole drilling is used to produce small holes through conductive materials, whether those materials are soft or hardened. 1 0 0 1 0 22 cm 0000524510 00000 n Expand your EDM capacity and capabilities without expanding your overhead. Electrical Discharge Machining Examples. Conventional machining of Inconel 706 results in a poor surface finish and a low-dimensional accuracy. 0000004142 00000 n 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. 0000513616 00000 n 0000546743 00000 n <<9971A0D6998C6844AD7192BA1778B426>]/Prev 828903>> Conventional drilling techniques simply can't match the accuracy and tolerances required for these types of jobs, especially for harder surface materials. The advantages of micro-EDM are more and more in focus for ceramic machining. 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. 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. 0000547350 00000 n 0000510817 00000 n “Since the tool does not touch the workpiece, there are no cutting forces generated; therefore, very fragile parts can be machined” . Machining with a hard and challenging material that also happens to be electrically conductive, EDM is a machining method you should consider for higher accuracy and cost-effectiveness. EDM micro hole drilling is used to produce small holes through conductive materials, whether those materials are soft or hardened. Several obstacles to chaining are automatically overcome when these instruments are used. (IMECS ) Tj © 2021 CAM Tech, Inc.

Call or email to see how we can help you with your project. 24.722 0 Td Haley notes that copper can be cut on wire EDM machines, but there are only certain graphites that can be cut on a wire machine - the particle size should be five microns or less. Atmospheric variations in temperature, pressure as well as humidity. 0000509875 00000 n Inconel 706 is a newly developed aeronautical material that has corrosion resistance along with high mechanical strength. (2010 ) Tj Hence, micro-EDM (electrical discharge machining) is utilized to machine Inconel 706. Hence, an appropriate combination of micro-EDM and micro-ECM could yield the advantages of these two processes while preventing their disadvantages (Zeng, Wang, Wang, Shan, & He, 2012). Nguyen et al. At CAM Tech, we provide quick turnaround times while maintaining a high standard of quality. The forces are very small because the tool and the work material do not come into contact during the machining process, hence eliminating mechanical stress, chatter and vibration problems during machining. In recent years, micro-EDM is strongly expected to be used for generating three-dimensional microstructures, such as micro-holes, micro-grooves and micro- Hoang KT, Yang SH (2015) Kerf analysis and control in dry micro-wire electrical discharge machining. EDM micro hole drilling can deliver precise drilling solutions for single prototypes, small product sets, and large production runs. As well known, die-sinking EDM is unsuitable for machining the complex 3D micro cavity less than 1mm due to the high-priced fabrication of 3D microelectrode itself … 53.589 0 Td 0000554796 00000 n (Vol ) Tj (of ) Tj Advantages and disadvantages: Some of the advantages of EDM include machining of: Complex shapes that would otherwise be difficult to produce with conventional cutting tools. 0 -7.842 Td startxref These advantages include the process of being a noncontact technology, an independency of material brittleness and hardness, a low impact on the material, and the achievable microstructures. endstream endobj 97 0 obj <> endobj 98 0 obj <> endobj 99 0 obj <> endobj 100 0 obj <> endobj 101 0 obj <>stream The spark generated by this process produces heat, which remove metal erosion...
