KR CYBERTECH nano series: Redefining compactness
The new KUKA KR CYBERTECH nano series stands for greater performance in the low payload category
20 October 2015
They have to be streamlined, agile and flexible and have a long reach in order to perform convincingly even in confined spaces. The increasing automation in General Industry is resulting in robots finding their way into ever more branches of industry. In addition to robustness, precision and flexibility, improved energy efficiency, agility and accessibility in confined spaces are also becoming increasingly important. The new KR CYBERTECH nano series from KUKA has all of these characteristics. Outstanding performance, smooth and sensitive motion characteristics on the path and during positioning: that is what this new class promises in the low payload category.
KR CYBERTECH nano consists of two product families – KR CYBERTECH nano for handling and assembly of small components and KR CYBERTECH ARC nano specialized in welding applications. Both families are available in different payload variants: the KR CYBERTECH nano with 6, 8 and 10 kg payload capacity with a reach of 1820, 1620 and 1420 mm respectively and the KR CYBERTECH ARC nano with 6 and 8 kg payload capacity with a reach of 1820 and 1620 or 1420 mm.
“The most important thing for us was to significantly improve the robot’s compactness and performance,” explains Markus Hollfelder-Asam, Product Manager for the new KR CYBERTECH low payload class at KUKA Robotics. “It worked perfectly. The volume of the new KR 8 R1620 is 47 percent less than that of its predecessor, the KR 6-2, despite the greater payload capacity and longer reach,” says Hollfelder-Asam. Thanks to the smaller footprint, it was possible to save space and material costs. “We have significantly reduced the disruptive contours of the robot, while the streamlined design of the wrist ensures utmost accessibility, even in confined workspaces.”
More compact, more robust, smaller footprint for for handling, assembly and welding applications
For material handling applications, the KR CYBERTECH nano product family is also available in a High Protection (HP) variant. In this variant, the entire robot has a protection rating of IP65 and is thus perfectly protected against dust and waterjets; what is more, with a protection rating of IP67, the robot wrist can also withstand high surface temperatures, permanently large quantities of dust, lubricants and coolants. Even temporary submersion has no adverse effects.
Furthermore, the KR CYBERTECH ARC nano welding robot, with its streamlined hollow-shaft wrist with bearings on one side and a diameter of 50 mm, allows positioning close to the workpiece. This configuration removes the risk for adverse effects on weld quality due to dangling dress packs. The infinitely rotating sixth axis means that no cycle time is lost turning the wrist back again, thereby boosting productivity. One feature that will particularly appeal to system partners and integrators in the welding sector is the generous free installation space on axis 3. This ensures optimal, space-saving integration of the welding cabinet right next to the robot. Compared to other welding robots, this means a substantial reduction of the disruptive contours and significant space savings in the cell.
