Industrial robot manufacturer Kuka has revealed its latest family of low payload robots, the KR Cybertech Nano series.
The robots are designed for continuous-path applications such as arc welding, adhesive bonding or sealants. According to Kuka, the series is characterised by a long service life and low maintenance requirements in the low payload category.
For users, the total cost of ownership is reduced to a minimum. This includes low operating costs due to maximum availability and reduced energy consumption compared with the series’ predecessor.
In addition to the drive and control technology, the service and maintenance requirements have been optimised. Individual axes, for example, are maintenance-free and spare parts are available for up to 25 years.
An upgraded 50mm Kuka hollow-wrist robot reduces main axis motion, allowing short cycle times combined with precision in motion. It also features repeatability of 0.04mm, even at high speeds.
Due to its small footprint and diverse installation options, the hollow-wrist robots are also suitable for compact cells, complex tasks and challenging process chains.
Additional flexibility is provided by Kuka’s K-PIPE-ES energy supply concept. Separation of the system and application cabling makes integration into the production environment 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.
The series also includes in-line wrist variants for handling focus and CP applications. The digital Kuka.Motion modes allow the performance of the robots to be adapted to different tasks via the controller, such as Dynamic Mode for greater dynamic performance with reduced cycle times.
Path Mode 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.
“We have developed the series specifically for the latest KR C5 controller generation from Kuka, which taps the full potential of our new overall system,” said Markus Hollfelder-Asam, portfolio manager at Kuka.
“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.”
The series also features as standard protection against dust and water in accordance with IP 54 for the hollow-wrist robots and even IP 65/67 (main axes/wrist axes) for the in-line wrist robots.
