Robot cables for 3D movements

Cores, stranded structure, shields and jacket materials must compensate for high alternating bending loads as well as cable diameter changes due to torsional movements. Filling elements are used which can absorb occurring forces such as torsions. For this purpose, PTFE elements and rayon threads are installed. This "mechanical stress" differs greatly between cables in a linear e-chain® system and a cable subjected to bending, torsional and centrifugal forces. This cannot usually be determined in advance. The igus® Torsion Test Standard was developed for this purpose. This standard allows a reproducible assessment based on meaningful test results. All CFROBOT cables with a fixed end distance of one metre are twisted at least 5 million times.

chainflex® cables for demanding robot applications

Wandres GmbH specialises in the development and production of brushing and air cleaning systems. The safe and careful removal of dust, fibres and the smallest particles on surfaces is a prerequisite for many production processes in order to produce high-quality products. In order to protect the 6-axis robots from mechanical damage, the robot cables were equipped with factory-supplied protective hoses. However, these could not stand the continuous operation and are permanently torn or frayed, causing the whole test facility to come to a standstill.
