摘要

The story of Sodick's 10 Year Positioning Accuracy Guarantee is rooted in the story of the Rigid Linear Motor. In 1998, looking for a way to reduce backlash and vibration, Sodick developed the Rigid Linear Motor - an axis drive system that replaced ball screws with a combination of rare-earth magnets and electromagnets mounted directly on the machine castings. The new technology, which controlled movement magnetically rather than mechanically, saw significant success and has since become a cornerstone of the Sodick brand. One unintended benefit of the new drive technology, as Sodick engineers began to notice, was that the positioning accuracy of the machine's axes was no longer deteriorating with use. By switching to a magnetic drive system rather than a mechanical one, Sodick had eliminated friction and torque, allowing for extended use without wear on the axis drives.
