AERONAUTIC SECTOR AERONAUTIC SECTOR Die sink electrical discharge machining as a viable option for the manufacture of turbine blisks ONA participates in research at the Aeronautics Advanced Manufacturing Center (CFAA) that concludes that electrical discharge machining is a "competitive and indispensable" alternative when the geometry of the blisk includes a difficult to access shrouded blisk where production shifts are short ONA has been involved in R&D+i for 65 years. An eagerness for innovation that explains our world leadership in electrical discharge machining. ONA's current engineers...

AERONAUTIC SECTOR AERONAUTIC SECTOR In one of the latest studies, conducted at the Aeronautics Advanced Manufacturing Center (CFAA) together with the research group of the University of the Basque Country (UPV/EHU), the complete sequence of operations required for the production of a blisk with a high geometric complexity for the aeronautics industry by means of die sink electrical discharge machining (SEDM) was analyzed. It is a well-known fact that the need to improve the efficiency of high-speed turbines has generated a trend towards the design of integrated components, i.e. manufactured...

AERONAUTIC SECTOR AERONAUTIC SECTOR fir-tree roots One of ONA's greatest challenges has been to develop EDM technology adapted to the process in order to convert electrical discharge machining into a competitive and high-quality machining process, even when compared to some of the most common processes in the industry, such as milling or broaching. An example of the latter is the cutting of fir-tree roots for aviation turbine discs, mainly manufactured by broaching. A successful project to highlight is the work carried out in collaboration with a company in the aeronautics industry, project...

AERONAUTIC SECTOR AERONAUTIC SECTOR The AV35 offers important advantages to companies, such as a lower initial investment in machinery, thanks to this adaptability, and more autonomy. The entire machining process is automated and rigorously controlled so that the part meets the requirements set out: Data and parameters are continuously provided to monitor whether progress is being made as programmed and, in the event of any error (a change in water temperature, etc.), a warning signal is emitted. Technology at the level of broaching and milling Discs are critical rotating parts in a gas...

CASE STUDIES CASE STUDIES PRODUCTION IMPROVEMENT SOLUTIONS Volkswagen Portugal: ONA modernizes Volkswagen Autoeuropa's fleet of EDM machines he Palmela (Portugal) car factory, one of the most important in Europe, acquired two ONA models (AV35 and QX4) for its part press and stamping area. Out of all the EDM brands the plant analyzed, ONA stood out 'for its optimum quality-price ratio' and 'for the commercial and technical assistance received throughout the sales process' Volkswagen Autoeuropa (Portugal), one of the most modern and important car manufacturers in Europe, chose ONA to...

CASE STUDIES CASE STUDIES 'We were able to see similar machines from other ONA customers in Portugal and also had the opportunity to go to the ONA factory, where we got to know some of the new machine manufacturing projects' Year founded: 1995 Volkswagen Portugal Q.ta da Marquesa IV 2954-024 Q.ta do Anjo Portugal Autoeuropa pointed out. Among the best companies in the world Volkswagen Autoeuropa today constitutes the greatest foreign industrial investment in Portugal. The Palmela plant, near the port of Setúbal, in the south of Lisbon, covers an area of 2,000,000 m2, employs 5,800 people...

CASE STUDIES CASE STUDIES Ningbo Heli Mould Technology, China: ONA automates mould manufacturing process, making production more cost effective Year founded: 1980 Ningbo Heli Mould Xiangshan Industrial Park 358 Xigu Road Ningbo, Zhejiang 315700 INGBO HELI MOULD TECHNOLOGY is the largest manufacturer of moulds for automobile engines in China. It bases its business philosophy on innovation and customer proximity. And it was these two features that led the company to confide in ONA as a supplier of EDM machines. Its equipment includes two EDM QX7 die-sink machines and a 90-position Erowa...

CASE STUDIES CASE STUDIES JR MOLDES Reinforces its Capacity with ONA's Technology T he Portuguese company, a benchmark in the automotive mold industry in Europe, has 4 ONA machines in its facilities in Oliveira de Azeméis. One of them is the TQX10, for machining large molds. JR MOLDES is a Portuguese firm specializing in manufacturing molds for plastic injection in the automotive industry, among others. The company has grown significantly in recent years, becoming 'quite a benchmark' in Portugal's and Europe's molding industry, as José Manuel Ribeiro, the company's CEO, says. Currently, JR...

CASE STUDIES CASE STUDIES LeRoy Tool & Die chooses ONA for its EDM needs T he American company, a leading manufacturer of rubber and plastic injection molds for companies in the North American automotive industry, values our automated solutions: 'The biggest challenge was to incorporate more stand-alone machine time, and ONA has really helped us achieve that' Proximity and high capabilities to offer customized solutions to very specific needs of electrical discharge part machining (EDM). These have been two of ONA's main virtues since we started our activity more than 65 years ago. These...
