Hydraulic rotary indexing table ATHN Series

verticalfor machine toolslarge

In the ATHN series, we rely on rotary indexing tables with non-lifting Hirth coupling, consisting of precise and hardened three-piece sets. This drive train is indexing, and for larger rotary tables we use up to 720 teeth, giving a maximum pitch of 0.5 degrees. Our ATHN rotary tables are equipped with a thrust bearing, which allows the face plate to remain in position even when unlocked. This guarantees particularly gentle operation even with high workpiece loads in large machine tools and rotary transfer machines. • Rotary tables as pallet receivers with zero-point clamping systems • Rotary tables as pallet receivers in accordance with DIN 55201 • Attachment tables • Built-in tables • Slide tables • Integrated linear x axis 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.
