Precisely more work pieces up to 500 tonnes

Our rotary, tilt and carousel rotary tables set a clear mark due to the extremely robust design as well as a high level of precision in the micrometre range, speed and repeatability. A suitable solution can be designed for every application case. We speak with our customers about requirements and work pieces, which are to be processed on the rotary tables. We create the right solution based on our experience from more than 600 projects. Our high-precision rotary tables can withstand a bearing load of up to 500 tonnes. If such masses are being moved, this requires high torques. If these masses need to be accelerated quickly, then they need to be braked quickly, and they need to be precisely positioned with accurate repeatability.

Whether a hydrostatic linear or rotary axis, roller bearing axles or also a combination with both, we have all the solutions in our portfolio. Hydrostatic guides help to avoid wear surfaces, for example at very high loads, and the tables are thus suitable for processing with the highest requirements and the highest accuracy. The best damping properties allow for longer tool lives and high-precision work piece processing. The decisive factor for the durability and precision of the rotary tables is not only the possible loading, but the largest possible bearing diameter in relation to the worktop size. The machine bed itself is very compact and space-saving. It is well-protected under the steel cover. All the necessary regulation and control elements are easily accessible in an power box located in the rotary table. Thanks to the standardised, plug-in-ready interface, the rotary table can easily be connected to all machine tools. 

In addition to rotary tables for positioning work pieces for milling work (also in interpolation operation), patented tilting tables with additional axes, for example, are among the repertoire. Due to the standard angular adjustment of up to 10°, these are suitable for milling large an heavy components and, for example, are used in wind energy technology. Pallet changing systems are used to automate machining centres due to the multiple pallets and the ability to set up during main working hours. Thanks to a powerful drive train design, our carousel rotary table achieves very high machining torques, which makes a very good machining performance possible. In addition to the milling, it is also possible to turn and grind work pieces.

The right solution for every application

  • The best technical values in terms of stability and accuracy with an excellent price-performance ratio
  • We achieve this with our knowledge and our user experience with a high vertical integration
  • The modular design makes it possible to realize different configurations depending on the customer requirements
  • Possible tables loads up to 500 tonnes
  • Working in the micrometre range, unmatched in the run-out, true running and repeatability
  • Our NC rotary tables are available without a shifting axis as well as with a W-axis/V-axis.
  • A central and easily accessible, integrated power box contains all the necessary regulation and control elements. The standardised interface allows for an easy connection and integration to the respective machine tool 
  • Integrated measuring systems in the highest precision, well-protected from additional covers and sealing air, ensure precise positioning
