The AccuteX AU-1440iA Z800 submerged wire EDM from Absolute Machine Tools is designed to process both large and small parts with accuracy and speed. The machine’s X-axis capacity of 55.11" (1,378 mm) with 39.1" (787 mm) in Y and Z enable it to handle workpieces ranging to 68.5" × 42.5" × 31.29" (1712 × 1062 × 782 mm) in size.

Designed via finite element analysis (FEA), the machine structure includes a Meehanite-cast honeycomb-type base, a highly ribbed column mounted with an oversized UVZ axis and a reinforced lower arm to increase stiffness. To maximize durability, the 5.9" (148 mm) U and V axes are protected in a cabinet located above the working area. All castings are stabilized to ensure maximum strength, reliable high precision and long durability when machining workpieces as heavy as 7,473 kg (16,440 lb). The rigid structure and 20-mm C1 Class U-V ballscrews provide repeatable precision at the high flushing pressures necessary for high-speed cutting, the company says.

The machine’s precision-hardened stainless steel workpiece-mounting table offers easy accessibility and is designed to function as a standard clamping system, enabling a range of workpieces to be fixtured quickly and accurately. The worktable can also accommodate virtually any commercial clamping system.

AccuteX’s automatic wire threading (AWT) system enhances machining speed by accomplishing fast, submerged rethreading at the break point. When wire breakage occurs, this rethreading takes place without dielectric drainage/refilling, resulting in spark-to-spark times as low as 15 sec. The system also includes a scrap wire disposal unit.
