Focus on precision and repeatability
“For the tool grinding center of type UW I F, we were looking for an automated solution which works with speed and precision. To ensure maximum flexibility, it was our aim to integrate a robot capable of performing various tasks into the system,” explains Gerhard Kopp, Head of Design at SAACKE’s Machines Division. When searching for a suitable partner, SAACKE chose KUKA. “The price/performance ratio as well as the flexible robot programming won us over,” adds Kopp.
The Design, Customer Service and IT departments were all involved in designing the fully automated system. This was to ensure, on the one hand, that the work processes were perfectly matched to customer requirements, and on the other, that the system would be easy to operate. The developers had to account for a number of special aspects in the design of the system. In order to be able to reliably complete the various tasks within the desired cycle time, for example, the robot was equipped with a double gripper.
A special program was developed for this purpose. With this program, the workpiece carrier can be emptied and loaded again in a single work step – a significant factor in boosting the efficiency. The robot cell was also designed to allow for it to be converted for other workpieces.
“The integration of the robot into the machine sequences required not only adaptation of the machine enclosure, but also development of a suitable interface between the robot and machine controllers,” notes Kopp, in describing a further challenge that has been successfully mastered.
