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; the division hereby is equivalent to a maximum of 0.5 degrees. The ATHN tables are designed with an axial bearing holding the faceplate in position during unlocking turning movement and locking. This ensures very smooth cycling with high workpiece loads in large machine tools and rotary indexing machines.
Frame sizes: ATHN 520 – ATHN 630 – ATHN 800 – ATHN 1000 – ATHN 1250 – ATHN 1600
