Abstract: A turret-type machine tool has a workpiece support that can be indexed incrementally by a step-drive and is locked to be stationary in angular positions corresponding to individual machining stations. In the individual machining stations, machining units are provided, each of them carrying a machining spindle. Workpiece holders are supported on the workpiece supports with planet axes located in at least one horizontal plane; the planet axes extend at a tangent to and radially spaced apart from the vertical switching axis of the workpiece support and are each aligned in pairs parallel to one another.
