With a rotary indexing table, the manufacturer is helping to increase the productivity of a well-known German car manufacturer. The Remscheid-based company developed the innovation with its customers Unior Werkzeugmaschinen in Slovenia. The rotary indexing table is, so to speak, the heart of a machine tool manufactured there, which is ultimately used to machine lightweight components for the production of electric cars. "It has a diameter of 3,000 millimetres and weighs ten tons," explains Marc Gronau, Sales Manager at Peiseler, "making it the largest and most sophisticated unit of this type that we have ever built in our 200-year company history."

The basis is the worm gear-driven Peiseler rotary table ATU 1600, which uses a direct path measuring system to cycle six two-axis swivel units of type ZATC 300 in five steps from one processing station to the next and then back to the starting position with a pilgrim step. The rotary indexing table therefore has a total of 13 axes and a maximum load capacity of 250 kilograms per station. They ensure high-precision simultaneous machining of the workpieces.

The Peiseler rotary indexing table is the center of the entire rotary indexing machine with five stations for drilling and milling as well as a loading and unloading station. "A special requirement for our design was not only to achieve maximum power density for highly dynamic cycle times in the smallest possible installation space," emphasizes Gronau. "In order to keep the tolerances, which are always present, as low as possible, it was also necessary to position each of the two-axis swivel units with the utmost precision in relation to each other." Another complex task was the media supply for clamping, releasing and monitoring the workpiece clamping device. A rotary distributor with eight channels was used for this.

"In this respect, we have not only built the largest rotary indexing table to date, but have also developed a customer-specific solution that ensures short cycle times and low unit costs in the production of electric vehicle components," says Gronau. Thanks to its high precision, Peiseler, as a manufacturer of turners, rotary tables, two-axis swivel units, swivel heads and tool change tables, also plays a part in the reliable production of future-oriented mobility.
