Custom 2 Axis System
This image shows a custom 2 axis system consisting of two 100 mm travel LRT-AEC linear stages and a RST240B-E Series rotary table for high load vertical and rotary positioning. The LRT stages use the lockstep synchronization feature of the X-MCC to move together for improved load capacity and stiffness. A custom base plate for the RST240 allows for flexible mounting and full access through the 101.6 mm aperture.
