<p>The rotary table (40) on a fixed base (30) at a machine tool, to carry a number of workpieces in steps through different workstations, has at least one workpiece clamp with a satellite (50) rotating on a rotary axis (55) in relation to the table through a satellite drive (53,54). The satellite has shaft (51) through the table, with a Hirth tooth structure at the lower end towards the base. An indexing unit (60) is at the base with a column or ring disk with a linear sliding movement parallel to the table axis (12), with a Hirth tooth structure at the end side towards the table which matches the teeth at the satellite shaft to index the satellite. The indexing unit is moved up to index the satellite, and down to clear the indexing action.</p> |
