Case Study: Diagnostic system with 3-axis linear positioner and super-high-precision rotary indexer
Technical Challenge
A global manufacturer of diagnostic equipment required a custom, fully tested and assembled XYZ platform with rotational positioning to allow continuous reagent processing. Extended lifetime to ensure uninterrupted operations was essential, as was greater rigidity and smoothness over lead screw-based actuators. Specified travel requirements, load conditions and envelope dimensions for their diagnostic equipment had to be met.
