The New Linear Motor Drive Revolution

Abstract

Sodick has been using the linear motor drive since 1999 successfully to bring a new revolution in the EDM machining field. Initially, the Die-sinker EDM was equipped with a z-axis liner motor drive which made high speed jumping possible and resulted in high speed machining. After this initial breakthrough, all wire-cut and die-sinker EDMs produced by Sodick were installed with linear motor drives for all axes of movement. Five years have passed since the initial production of linear motor driven EDMs and many of these earlier machines still maintain high levels of accuracy. In the future, linear motor driven machines will become more and more a necessity to ensure the creation of precision molds with high repeatability.
