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.
