Rigid Linear Motor Drive System

The AD55L Sinker EDM features Sodick’s Linear Motor Drives. Linear motor drives have been a perfect fit for CNC Sinker EDMs. The linear motor’s fast 1,400”/min axis feed combined with high 1.2G acceleration creates its own natural and even flushing condition. The positioning accuracy of Sodick’s linear motors are guaranteed for 10 years on all Wire and Sinker EDMs.

The LN Controller and Power Supply Unit

The LN controller will maximize the advantages of the linear motor drive system. “LN Assist” (standard) will enable even a beginner to operate the machine with ease. The power supply unit is designed to conserve energy.

SVC Circuit + No Arc Machining

The “SVC” Circuit is the Sodick standard in the process of achieving *Zero electrode wear and high-quality surface finish. To create a uniform satin surface, the “SVC” enables a no-polish finish for micro and non-forms that are difficult to polish, by producing high grade surface finishes equaling shorter processes, improved quality and prolonged stability.


The new electrical supply discharge circuit “Arc-less” enables no arc machining. It greatly reduces the machining time and number of electrodes used, leading to a dramatic reduction in cost and human errors.
*Zero electrode wear is an electrode wear rate of less than .06%.

New NC Unit with ``TMM3`` Discharge Power Supply

The AD55L features Sodick’s latest LN NC unit equipped with the new “TMM3” discharge power supply, capable of high-speed, high-precision and high-efficiency machining. It is equipped with LN Professional, automatic programming functions.
