For ergonomic workplaces

New variable 2-axis positioner for welding applications

Skilled workers in automotive production work many hours every day in a demanding environment. This necessitates an increased focus on workplace ergonomics in the automotive sector. A new variable 2-axis positioner from Nabtesco helps to boost ergonomics: The RSX-40K rotary table allows the operator to move the workpiece or assembly to the optimal height and position for machining.


Exact positioning of the workpiece or assembly for machining


Plug-and-play solution for the constantly increasing demands of automotive production


Can be adapted to the exact personal requirements of different operators

Ergonomic and economical positioning

The RSX-40K variable rotary table features two axes: one for rotating and one for tilting. Both axes are equipped with hollow shafts to enable the feed-through of supply cables for the fixing and clamping devices. The extremely flat rotary table can hold a payload of 4 t and has a positioning accuracy of <1 arcmin. An additional swivel axis provides for even better ergonomics: It enables exact positioning of the workpiece in accordance with the operator’s personal requirements.

The swivel axis also allows tilting of +/- 16°, which enables the system manufacturer to implement the exact height needed for loading of the positioner. The system can therefore be adjusted individually to create an ergonomic workplace for different employees. This results in a substantial competitive advantage over conventional positioning systems.
