The AD55L Sinker EDM is built around Sodick’s proprietary Rigid Linear Motor Drive System, providing unmatched performance through high-speed, rapid acceleration, and precise positioning across the generous travels of 23.62 inches (600 mm) in X, 15.75 inches (400 mm) in Y, and 15.75 inches (400 mm) in Z. The machine’s core innovation lies in its improved structure with optimized rib arrangements, which results in approximately a 70 percent increase in rigidity, minimizing machine deformation for optimum performance at high speeds. The positioning accuracy of these flat rigid linear motors is backed by an industry-leading 10-Year Positioning Accuracy Guarantee.

Equipped with the new LN NC unit and the “TMM3” discharge power supply, the AD55L maximizes efficiency and precision. The machine features the SVC Circuit—Sodick’s standard for fine finishing—which enables a no-polish, uniform satin surface finish while achieving an electrode wear rate of less than 0.06 percent. Additionally, the Arc-less electrical supply discharge circuit significantly reduces machining time and the number of electrodes required, leading to dramatic cost and error reductions. With a Max. Workpiece Weight capacity of 2-204 lbs (1-000 kg) and a work tank size of 47.25 inches by 31.50 inches, the AD55L is an ideal solution for large, demanding workpieces in the mold, die, aerospace, and energy industries.
