What ONA Electroerosión does

ONA Electroerosión (ONA EDM) is a Spanish-based, privately held manufacturer of Electrical Discharge Machining (EDM) equipment, founded in 1953 and operating as one of the longest-established names in the EDM sector. The company's core technology uses controlled electrical discharges to erode complex geometries in hard-to-machine materials such as superalloys, a capability it sells into four primary verticals: turbomachinery (turbine blades, blisks, fir trees, nozzle guide vanes), automotive, microelectronics, and moulding. Its product portfolio spans die-sinking EDM machines featuring what the company describes as the highest-power digital generator in the market and an integrated ecological filtration system, wire-cut EDM machines positioned for up to 30% time savings through improved surface finish, the ONA HALLEY 4 fasthole EDM for turbine applications, a dedicated microholes EDM line, and the ONA SAMYLABS subsidiary focused on additive manufacturing.

The company operates a direct enterprise sales model, with technical consultation throughout the customer journey and close involvement in process start-up. It supplements hardware sales with integral customized solutions covering software, electrodes, program generation, and special machine design, effectively a hybrid capital-equipment plus engineering-services revenue model. Pricing is quote-based and not publicly disclosed. ONA reaches customers through a multilingual web presence covering seven languages and 60 countries, supported by sector-specific content, case studies, and the ONA Academy training program, and reports a cumulative installed base of 15,000 machines with claimed 98% Overall Equipment Effectiveness.

ONA remains privately held with a small headcount of 11-50 employees, no disclosed institutional investors, and no public ownership structure. Its strategic posture is that of a heritage specialist: deep technical expertise and customization capability in a narrow industrial niche, with a recent directional move into additive manufacturing via SAMYLABS as its most material diversification beyond core EDM.
