Click image to enlargeGF AgieCharmilles’ third generation Automatic Wire Changer is now available on the company’s latest, high performance Cut 2000 and Cut 3000 wire cutting EDM machines.

With the optional Automatic Wire Changer, wire EDM operators can easily switch between different wire diameter sizes and types, optimizing both roughing and finishing operations and reducing production costs.

A manufacturer, for example, could use a larger diameter, less costly brass wire for rough passes where the emphasis is on high stock removal, and smaller diameter wire, which is often more expensive, for intricate details and fine finishing passes. The most dramatic results occur when working with parts requiring the use of wire diameters 0.004 inches (0.1016 mm) or smaller.

The Cut 3000 EDM machine from AG AgieCharmilles

The Cut 2000 and 3000 machines employ universal wire guide systems, enabling them to accommodate wires from 0.30 mm (0.01 in.) down to 0.05 mm (0.002 in.) for micro-machining and super-precision applications. The automatic wire thread and rethread capabilities of these machines also facilitate unmanned, lights-out production, and the Vision 5 numerical control allow for quick, easy organization and management of multiple unattended jobs.

The machines are also equipped with a digital Intelligent Power Generator, or IPG, and Variocut for reliable machining of even the most complex parts and for achieving surface finishes as fine as Ra 0.05 μm.

Featuring compact footprints, the machines have rigid bases as well as precise integrated measuring systems for lifelong, repeatable accuracy. Both machines also manage and minimize thermal distortion generating from various machine sources, including generators and pumps, which have their own individual cooling systems.

The 2000 machine has X, Y  and Z axis travels of 350 mm (13.8 in.) x 250 mm (9.8 in.) x 256 mm (10.1 in.), respectively. When considering the machine’s fluid bath, the 2000 can accommodate submerged workpieces weighing up to 200 kg (440 lb) and unsubmerged workpieces up to 451 kg (992 lb). The machine also achieves taper cuts of +/- 30° over 100 mm (3.93 in.) in height.

The larger 3000 machine has X, Y and Z axis of 500 mm (19.7 in.) x 350 mm (13.8 in.) x 256 mm (10.1 in.), respectively. When considering the machine’s fluid bath, the 3000 can accommodate submerged workpieces weighing up to 400 kg (880 lb) and unsubmerged workpieces up to 801 kg (1,763 lb). The machine also achieves taper cuts of +/- 30° over 100 mm (3.93 in.) in height.
