Abstract

A program-controlled machine tool is described, for machining workpieces by means of rotary tools which can be brought into engagement with a workpiece under timewise control. The workpiece is disposed on a cross table which rests on a program-controlled rotatable workpiece table which in turn is guided along a first main axis. The tool support region has a vertical support post which bears on its top a translational carriage which is vertically adjustable and is movable in a direction perpendicular to the vertical. Such carriage further bears tool mounts. The mounts comprise a common revolving head the rotational axis of which coincides with the vertical movement axis of the said translational carriage. The revolving head has at least two program-controlled rotatable tool tables the rotational axes of which perpendicularly intersect the rotational axis of the revolving head in a single point. The rotatable tool tables are also program-controlled and bear holding members for various working units, e.g. working spindle means sleeves and/or auxiliary working assemblies, each of which working units is adjustable along another translational axis which is perpendicular to the rotational axis of the particular rotatable tool table which carries the respective working unit.
