Precision Experimental Tables

TSW specialises in the design, manufacture and supply of motorized experimental tables with several degrees of freedom that are stable and combine accuracy with high load capability.

Utilising ball screw jacks with backlash elimination arranged in pairs and each pair powered by a single stepper motor offering via cross slides X,Y,Z axis translation and pitch/yaw. The mounting platform is essentially either a precision ground steel plate or a breadboard that provides a matrix of holes on a grid pattern which is a hollow honeycombed structure providing a combination of high rigidity, low weight and excellent damping properties. Precision is controlled via the stepper motor gearing translators/controllers and encoders with limits set by high precision micro-switches.

Fig 1 below shows a theoretical resolution of an experimental table
