Wire EDM Machine Larger than Any Other Cuts Totally Submerged Tall Workpieces
Industry Roundup: New Products & Services
 The ONA AF130 wire-cutting EDM machine is considered the largest machine of its type in the world. Part of the AF Modular series developed by ONA Electro-Erosion S.A., it is designed for versatility; every customer can configure its own unit with a high degree of flexibility. The various elements from which the x-, y-, u-, v-, and z-axes are assembled are prefabricated modules. This makes machine assembly swift and simple, enabling a customized system to be delivered with the same price and lead time as a standard machine.
Purchasers of AF Modular machines can choose to have an 800-, 1,000-, 1,500-, or 2,000-mm x-axis. Y-axis travel options are 800, 1,000, 600, and 1,300 mm. The z-axis choices are 500, 600, or 700 mm. The German customer that recently took delivery of the largest wire EDM machine ever built has an AF130 model with x-y-z travels of 2,000 x 1,300 x 700 mm. Its working area has a volume of 1,820 dm³. The machine can handle, with ease and precision, workpieces weighing as much as 10,000 kg and having dimensions as great as 2,450 x 2,000 x 700 mm.
Machines in the AF Modular series can cut workpieces as tall as 700 mm in the totally submerged mode. Additionally, they employ the ecologically sound ONA Aqua Prima filtering system that uses calibrated mineral particles as filtering elements, rather than filtering cartridges; these particles are neither lost nor expended and need no replacement during the filter’s lifetime.
ONA AF Modular models include a high-power ONA Easycut digital generator designed to achieve cutting speeds of 450 mm²/min with 0.33-mm wire and 370 mm²/min with 0.25-mm wire. This generator, by enabling such rapid cutting, prevents oxidation and pitting of the workpiece surface, which can have a finish as good as 0.2 µm Ra (6 VDI).
