The Machine Training Center (MTC) of Liebherr-Verzahntechnik GmbH in Kempten offers bright training rooms equipped with the latest technology the world of gear making has to offer including an LC 280 gear cutting machine with ChamferCut device, an LGG 280 gear grinding machine and a WGT measuring machine.
Here, the participants find out in detail what the machines can do, so that later they can fully and efficiently exploit that potential—and they do this by manufacturing real workpieces. After completing the training, they receive a certificate. If any questions arise when they return to their day-to-day work, they can ask the service team for advice.
Up to eight cameras transmit images from different perspectives inside the machine to large monitors. Even the smallest components of the machine electronics can be easily seen by all participants using the visualizer. Various scenarios can be tested on simulators without the risk of damaging an expensive machine. “The simulators take away the fear of breaking something. Everyone is then much more relaxed when they actually come to use the machine,” said Markus Bahsler, head of the Liebherr Academy. “The training teaches them to use the ideal parameters.”
Liebherr also offers individual, modular and topical training on the maintenance of the mechanical and electrical systems. The mechanical training courses focus on troubleshooting and geometric testing of the machine axes, and on carrying out the necessary adjustments so that the machine can produce with the highest quality. They also include analysis of the fluid diagram and cooling systems as well as replacement of specific drive components and wear parts. The electrical training courses focus on data backup, the PLC program structure and cycle diagnostics, adjustment of measuring systems as well as advanced troubleshooting and fault elimination. The company’s own personnel are trained this way to correctly analyze and repair the machine.
The practical handling of the machines is best learned on site. However, thanks to the Academy’s modern media technology, subjects such as programming can also be easily taught in online training courses.
“Our camera technology for live online training conveys images and situations that you can otherwise only experience live—and in some cases it’s even better,” said Bahsler. In the online format, for example, flexible, user-defined dressing of grinding worms with single or multiple starts can be practiced using a form disc with point or line contact. Didactic elements maintain the attention of the participants and ensure that what they have learned remains firmly anchored. The live online training is ideal for anyone who is experienced and familiar with operating the machine. Participation is possible practically anywhere in the world, thus saving travel time and costs.
Small groups of no more than six people and the latest media technology ensure that the training is as effective as possible. “At the MTC, the participants are not distracted by day-to-day business and can concentrate fully on the subject at hand,” said Bahsler. “And they don't just look over the trainer’s shoulder, they practice on real workpieces themselves. As you can see, real chips are flying here!”
Businesses benefit from increased process reliability and efficiency. If the operating personnel can get the best out of the Liebherr machines, productivity can be increased and there are fewer downtimes and disruptions.
