Machine tool having two machining units movable along a long x axis

A machine tool for machining workpieces, comprising:

• a left-hand machining space with a left-hand workpiece table configured for mounting left-hand workpieces and a right-hand machining space with a right-hand workpiece table configured for mounting right-hand workpieces;
• and
• a left-hand machining unit, movable along an X axis, with a left-hand working spindle configured for machining workpieces, and a right-hand machining unit, movable along the X axis, with a right-hand working spindle configured for machining workpieces, wherein the left-hand machining unit is movable between a left-hand end position and the right-hand machining unit and the right-hand machining unit is movable between a right-hand end position and the left-hand machining unit;
• wherein, when the left-hand machining unit is in its left-hand end position and the right-hand machining unit has been moved until it is in abutment against the left-hand machining unit, the right-hand machining unit is arranged at least partially in the left-hand machining space in order to machine left-hand workpieces and/or, when the right-hand machining unit is in its right-hand end position and the left-hand machining unit has been moved until it is in abutment against the right-hand machining unit, the left-hand machining unit is arranged at least partially in the right-hand machining space in order to machine right-hand workpieces;
• wherein least one bottom rail extends along the X axis, in which both a left-hand travelling column of the left-hand machining unit and a right-hand travelling column of the right-hand machining unit are guided so as to be movable in the X direction;
• and
• wherein the left-hand travelling column and the right-hand travelling column are each L-shaped with a short horizontal leg, which is guided so as to be movable in the at least one bottom rail, and with a long vertical leg, which carries the working spindle, and are arranged along the X axis with the free ends of their horizontal legs facing one another.
