Submerged Wire EDM Provides Large Capacity, Flexibility and Speed

The AU-1440iA Z800 submerged wire EDM from Absolute Machine Tools is engineered to process large as well as small parts with accuracy, speed and convenience.

The AU-1440iA Z800 submerged wire EDM from Absolute Machine Tools is engineered to process large as well as small parts with accuracy, speed and convenience. 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 up to 68.5" x 42.5" x 31.29" (1,712 mm x 1062 mm x 782 mm) in size.

The machine structure, designed via Finite Element Analysis (FEA), includes a Meehanite cast honeycomb-type base, highly ribbed column mounted with 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, high precision and long durability when machining workpieces as heavy as 16,440 lbs (7,473 kg.). 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.

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

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