ATHN

Round table with non-lifting Hirth coupling

In the ATHN series, we use three-piece sets of non-lifting Hirth couplings. NC operation with this technology is not possible; the tables work with indexing. We use the maximum number of 720 teeth for larger tables, with distribution equivalent to a maximum of 0.5 degrees. The ATHN tables are designed with an axial bearing, which holds the face plate in position during unlocking, turning movement and locking. This method ensures very smooth cycling with high workpiece loads in large machine tools and rotary indexing machines.

Drive type

Hirth couplings

Peiseler designs and produces lifting and non-lifting Hirth couplings for indexing processes. NC operation is not possible with this technology. Hirth couplings transfer very high loads, particularly tangential moments. They have a very high positioning repeatability. In the non-lifting variant, the rotary tables are designed with an axially fixed bearing. With this special design, the face plate remains in position axially during all movement sequences. Designs with a lifting Hirth coupling lift the face plate by a few millimetres for turning.
