In the SKHN series, we use three-piece sets of non-lifting, hydraulically actuated Hirth couplings. NC operation with this technology is not possible; the tables work with indexing. The SKHN series is designed with an axial bearing, which holds the face plate in position during unlocking, turning movement and locking. The large-area, full-circumference form-fit between the face plate and the housing allows this series to achieve high tangential forces and tilting moments combined with high repeat accuracy. Perfect for use in grinding centres.

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.
