The force-closed TÜNKERS® circular tube system utilises, from a technical point of view, the optimal moment of inertia of tubes and achieves an optimal relation between low weight, high rigidity and minimal vibration as opposed to square-shaped forms.
Gripper systems have a standard base plate or a customised bracket which is equipped with a hole pattern for connection to the robot flange. Onto this bracket the tubes are mounted which in turn are interconnected via cross clips.
The high-precision circular tubes are available in the diameters 60 mm, 40 mm and 25 mm. Aluminium can be used for nearly all applications, whereas carbon is mostly used for weight optimisation, and steel tubes are used for applications with extreme demands on rigidity.
