Abstract
Abstract A machine tool with a rotary work spindle and a cross-slide having a lower carriage and an upper carriage movable on the lower carriage in a direction normal to the direction of movement of the lower carriage. One of the carriages is movable normal to the axis of the work spindle. A turret is mounted on the upper carriage indexible about an axis located in a plane including the axis of the work spindle. The turret is provided with at least two groups or rows or receiving means for tool holders which are disposed in two parallel planes spaced in direction of the turret axis from each other.
