High automatic stacking of distribution transformer cores – Ground for smart manufacturing

The newly developed GEORG autostack 400 is an offline system for the automatic stacking of distribution transformer cores, developed within the cooperation between GEORG and GÜDEL.

This highly automated system is equipped with an interface to GEORG core cutting lines and an integrated data management for core production. The direct data transfer from the cutting line to the robot unit makes time-consuming manual processes redundant.

By this data coupling, the new systems can be easily integrated into digitally networked environments and thus prepare the ground for industry 4.0 / IoT.

GEORG and GÜDEL are looking forward to continue their cooperation in the field of automatic core stacking by developing autostack systems for medium and large power transformers.

Grinding tests for customers in North America

In our facility located in Roanoke/Virginia our (potential) customers can carry out grinding tests on their own rolls using a state-of-the-art GEORG ultragrind SG 2. This demonstration machine in our Northamerican show room is equipped with the world’s most modern grinding machine control system i.e. the GEORG smartcontrol. At our Roanoke facility, we also manufacture and assemble our smallest roll grinding machines of the GEORG ultragrind SG 1 series. Meanwhile we have supplied more than 100 machines of this type worldwide. From the next bigger series now a GEORG ultragrind SG 2 is ready for demonstration and testing in Roanoke. Convince yourself about the easy operation and performance of the machine in interaction with the modern control system. In case of interest please contact Jochen Münker,
