the 3½m-high slide and 4m-high crown, before all three components were fixed in place by four tie rods. It took Schuler’s experts around four months to complete the construction. The huge press is the fifth line with ServoDirect technology used by the Craemer Group.

ELEVEN metres above ground, 15m long, 8m wide and almost 1,000 metric tons in weight: automotive supplier Craemer started production on the largest servo transfer press Schuler has ever built. The specialist for metal forming, plastics processing and tool making is using the line with its 8m-long and 2.5m-deep press bed for the manufacturing of structural parts. The press bed needs to be so large as the parts are transported through several stations during the forming process. In the past, Craemer had to use two presses in line, which were linked by a total of three automation systems. The fact that the same process is now handled by just one machine enhances the overall reliability of the line, especially as parts no longer have to be passed from one press to the next. Within the new line, parts are transported by a tri-axis high- performance transfer system supplied by Schuler Automation with a span of over 10m. Its low vibration ensures fast and reliable part transfer. A prerequisite for this reliability is the integrated active vibration dampening (AVD) system developed by Schuler Automation. Each of the motors delivers over 500kW of power to generate a total press force of 25,000kN. The servo press took nine days to transport from Schuler’s plant, via ship, two special cranes and three trucks with 16-axle trailers. Once at the Craemer facility, the press bed was first lowered into the 6m-deep cellar of the specially constructed hall. This was followed by
