The new KR CYBERTECH nano ARC is setting the pace in automated production

16 March 2021

As part of the new generation of the KR CYBERTECH nano robot series, KUKA is now presenting the specialists for continuous-path applications such as arc welding, adhesive bonding or sealant application: the brand-new robots of the KR CYBERTECH nano ARC family. In the low payload category, the industrial robots deliver maximum performance at minimal costs.

The KR CYBERTECH nano ARC product family is setting new standards: the new generation of robots from KUKA is agile, extremely fast and even more precise than its predecessors in continuous-path applications. The upgraded 50 millimetre KUKA hollow wrist reduces main axis motion, allowing short cycle times combined with utmost precision in motion. 
The new robots in the team from the Augsburg-based automation specialist feature repeatability of 0.04 millimetres, even at high speeds, making the KR CYBERTECH nano ARC robots predestined experts for applications requiring maximum precision – such as arc welding and applying adhesives or sealants. 
Low maintenance requirements and overall costs
At the same time, the series is characterised by its long service life and the lowest maintenance requirements in the low payload category. For users, the total cost of ownership (TCO) is reduced to a minimum. This includes low operating costs due to maximum availability and reduced energy consumption compared with its predecessor. 
In addition to the drive and control technology, the service and maintenance requirements have also been optimised. Individual axes, for example, are completely maintenance-free and spare parts are available for up to 25 years.
Small footprint, wide range of possibilities
The robots can be used for a broad spectrum of applications: thanks to the small footprint and diverse installation options, they are also suitable for compact cells, complex tasks and challenging process chains. 
Additional flexibility is provided by the innovative “K-PIPE-ES” energy supply concept with which KUKA customers are already familiar from higher payload categories. Separation of the system and application cabling makes integration into the production environment even easier and the equipment of the energy supply system more flexible. Additional axes and the new generation of positioners can be added to the configuration more easily. 
Welcome to the family
The KR CYBERTECH nano series of the latest generation includes not only the hollow-wrist models of the KR CYBERTECH nano ARC family (ARC focus), but also in-line wrist variants in the KR CYBERTECH nano family (handling focus, also suitable for CP applications) which are even more flexible in terms of installation: as well as on the floor or ceiling, the in-line wrist robots can also be installed on a wall or at any angle. 
The digital KUKA.Motion Modes allow the performance of the robots to be adapted to different tasks via the controller, e.g., with the “Dynamic Mode” for greater dynamic performance with reduced cycle times. “Path Mode” even comes as standard in the hollow-wrist robots together with so-called absolutely accurate calibration for application-optimised continuous-path motion. Both options are also available for in-line wrist robots. 
Best results right from the outset
“No matter what tasks you use the latest-generation KR CYBERTECH nano for, the robots offer outstanding results right from the outset and can be optimally adapted using the flexible K-PIPE energy supply system and the KUKA.Motion Modes,” says Markus Hollfelder-Asam, Portfolio Manager at KUKA. “We have developed the series specifically for the latest KR C5 controller generation from KUKA, which taps the full potential of this new overall system. A powerful and flexible overall package.” 
The product series also features – as standard – protection against dust and water in accordance with IP54 for the hollow-wrist robots and even IP 65/67 (main axes/wrist axes) for the in-line wrist robots. “Integration of the KR CYBERTECH nano is really easy for companies thanks to the standardised mounting surfaces for accessories and identical footprint to that of its predecessor,” says Markus Hollfelder-Asam. “The installation of welding equipment is also uncomplicated. Once again, it can be adopted from the predecessor thanks to the identical mounting points.”
