2022 is undoubtedly a very special year for ONA. We are celebrating a 70-year proven track record in a sector we are passionate about. A path full of milestones and technological breakthroughs that have consolidated our leading position in the EDM market over the last few years. We firmly believe that a more sustainable and humane economic system is possible and therefore we focus all our business efforts on achieving a circular economy that is truly beneficial for everyone. The motto EDM for a Better World inspires an ECO growth model that puts the spotlight on resource efficiency and waste...

This year, ONA is strengthening its leadership in the aeronautical industry developing new applications for the manufacture of components such as impellers, turbine discs or fan blades. Our extensive experience and in-depth knowledge of EDM has allowed us to develop, together with two manufacturers in the sector, the best manufacturing solutions for the production of our customers’ parts. Furthermore, ONA continues to be a major player in the manufacture of both wire and die sinking large size machines. Our catalogue includes the world's largest wire cutting machine, e Including in our catalogue....

AEROSPACIAL INDUSTRY We have been involved in aerospace and turbine projects for over 25 years, clearly proving that EDM is a cutting-edge solution at the forefront of these industries. Many of the largest companies have already put their trust in us, enjoying the benefits of our EDM machines in the manufacture of parts such as turbine discs, open and closed impellers, blisks and many other components. ONA has a customer-oriented business strategy based on EDM technology and applications specifically for use in aerospace and energy gas turbine components. Our aim is to provide high added value...

TECHNOLOGICAL AEROSPACIAL INDUSTRY LEADERSHIP DRILLING DIFFUSER HOLES NA's business strategy in the aeronautical industry largely involves providing companies with customised, high added-value solutions. One example of this was the development of a custom application for an important manufacturer of high- quality components used in the aerospace and energy industries. Their need for such high-quality products was a key factor in their decision to opt for ONA. The customer required a solution for drilling diffuser holes in turbine blades. These holes play an important role in ventilation and cooling....

TECHNOLOGICAL LEADERSHIP AEROSPACIAL INDUSTRY How we managed to do it One difficulty in implementing this project was the global situation at the time. Finding ourselves in the middle of the Covid pandemic, face-to-face meetings between ONA's team and the customer were impossible. This challenge was met thanks to the excellent collaboration between ONA's different departments and our digital expertise, which allowed us to eventually send a telematic tender to the end customer. this scenario, a \ Incomplete simulation was performed in our CAD/ CAM. Faced with this scenario, and for the customer...

TECHNOLOGICAL AEROSPACIAL INDUSTRY LEADERSHIP 1\ Feasibility and final quality assessment study. First, a feasibility and final quality assessment study was carried out to check whether the test could be carried out using an ONA machine. This simulation was carried out in China on a machine in the subsidiary's showroom. One of the conclusions of this preliminary feasibility study was the suitability of the ONA IRIS6 machine given the characteristics of the project: the size of the parts and need for a rotary table to drill all holes and be able to rotate the workpiece. In the case of the electrode,...

4\ View and link with CAD-CAM the new CNC. The customer asked to be shown the new CNC software and how it links to CAD/CAM. ONA uses both software systems to obtain the best matching, so that the "ideal" part created by CAD/CAM software is processed by the machine's CNC and the final result is an exact replica of what was designed. In this particular case, it was very important to pinpoint the holes that had already been drilled, to determine the exact coordinates in real time and ensure that the machine was able to perform the operation at the exact spot. The set-up of the workpiece was crucial,...

TECHNOLOGICAL AERONAUTICAL AEROSPACIAL INDUSTRY LEADERSHIP INDUSTRY Electrical discharge machining (EDM) of turbine impellers for industrial compressors T wo of ONA's strengths in the turbine component manufacturing industry are based on our expertise in electrical discharge machining (EDM) of highly complex parts, as well as over 25 years of experience in providing turnkey solutions for the turbine industry. This market leadership and expert knowledge is what has led one of the benchmark companies in the manufacture of pumps and valves to place its trust in ONA to develop the turbine impellers...

AEROSPACIAL INDUSTRY Sectioned piece with interior cavities. Paths to access the material. Cavity to be made by the spindle. Design of electrodes to make the cavity. How we managed to do it Based on the drawings provided by the customer and the needs expressed, ONA’s team assessed the suitability of using die sinking EDM technology in the machining of geometrically complicated parts such as the impellers. 1\ Layout. In this initial phase, it was essential to correctly define the axis involved in the process, as well as the position and orientation of the workpiece, since both factors significantly...
