Abstract
Multispindle-automatic turret lathe with a spindle support mounted for rotation about a central indexing axis on a headstock and in which are mounted several workspindles, and with a main driving motor for a drive shaft which is adapted to be drivingly coupled with that workspindle which at any given time occupies the working position. Since it is regular custom to provide such main driving motors with electronic control units which not only control acceleration and deceleration of the workspindle which happens to be driven at any given time but which also allow the latter being stopped precisely in a clearly predefined angular position, a separate drive for the spindle support may be dispensed with by coupling the spindle support with the main driving motor for its intermittent indexing rotation movement.
