K-SMC™ M4Link Motion Controller


Sodick’s K-SMC™ M4Link (4th generation) industrial motion controller utilizes multiple central-processing units to yield the highest level of motion speed and accuracy performance. K-SMC™ M4Link is capable of controlling up to 32 axes and has been designed for Sodick’s linear motor-driven wire EDM, CNC sinker EDMs, CNC small hole EDMs, high speed mills and for 3rd party builders of manufacturing and automation equipment. Thanks to the K-SMC™ M4Link, 32 axes movement capability, Sodick machines can be equipped with auxiliary rotary tables (to produce parts for the energy, and medical industries) and factory automation systems.
