4 Axis Motion System

This 4-axis system is a combination of standard products, customized products and a custom developed air bearing vertical stage.

This custom developed XXZƟ-motion system is 2,4 meters long and contains two horizontal air bearing stages with a travel of 1 meter each. They run on the same granite base, guaranteeing a perfect alignment. On one horizontal air bearing stage, a vertical air bearing stage is built that holds a standard LAB RT150S air bearing rotary stage. All axes can be driven and synchronized with LAB’s motion controllers or with commercially available controllers.
