Rising demands for productivity and precision are leading to new machine concepts and processing strategies for tool machines. To meet the new request of these technologies all involved sub-systems must be taken into account for the development, also the clamping jig, which was neglected badly during the past. So one part of the research project “MaschinenbauInitiative Next Economy” was the development of a hydraulic clamping jig for dry milling processes, which can be integrated into compensation concepts of tool machines very easily. As a result, the demonstrator can hand over data of temperatures, positions and forces to the PLC without need of an excessive amount of additional hard and software.
