Articulated robot RTE 400 series

More than 40 years experience in the development of welding robots and planning of production plants appear in a extensive range of system modules. The main module is the igm robot series RTE 400. Benefits, typical for igm robots: •Outstanding programming techniques with both the K6 programming teach pendant and the offline teaching system. •Large work zone and perfect welding access to seam positions due to an optimal axes geometry and mounting of the welding torch in the wrist axis, implemented as a hollow shaft. •All cables are inside the robot arms using hollow shafts. The particular features of the RTE 400 modular robot system are the extremely slim robotic arms, optimized for weight and rigidity. For axes 2 and 4 there are available different lengths, the right range of movement can be selected for any application. The highly dynamic, maintenance-free AC servo motors and outstanding characteristics of the joint construction of rigid cast aluminium guarantee a high rotational speed and quick acceleration on all axes. The motors are equipped with holding brakes, there is no need for calibration after turning the robot off. The drive forces are transmitted by maintenance-free Cyclo gearboxes. Their use permits not only rapid positioning and high-precision path accuracy, but also keeps the number of parts used – and thus the number of replacement parts needed – low. ARC WELDING IN HIGH PRECISION The robots are designed specifically for arc welding: one unique feature is that all the media needed for welding are directed first through the main axis and then through the hollow shaft into the wrist axis, allowing the welding torch to complete two full turns.
