  • Tool turret with reduced switching times
    Patent number: 5339504
    Abstract: A tool turret includes a turret housing and a turret head rotatably mounted in and relative to the turret housing to selectable angular positions about a rotational axis. A preliminary indexing bolt secures the turret head in one of the angular positions following movement of the turret head between angular positions. A three-phase synchronous motor forms a rotary drive for the turret head and has at least first and second sets of pole pairs. The first set provides a first indexing speed. The second set has a smaller number of pole pairs then the first set and provides a second indexing speed. An interlocking member securely interlocks the turret head in any of angular positions.
