universal test stand
A gantry with PLT240 for gantry stages and an PLT320 for the traverse. The traverse is carrying three PLT165 for height adjustment of the sensors. All stages are driven by ball screw drives with AC-servos. For increased stiffness and hence higher Eigen frequency the traverse is backed with aluminum foam. Solid state decoupling joints guaranty easy control and help overcome over constraint. The positioning system is designed for a load of three times 20 kg. Travel is 500 x 700 x 100 mm.
