1. A machine tool, comprising:
a frame;
a first tool spindle and a second tool spindle;
a fixed gantry, which is supported by the frame, for supporting the first tool spindle and the second tool spindle, wherein a gantry recess is formed in the gantry through which a working space is accessible;
a workpiece table having at least one workpiece support location for supporting workpieces;
a first tool magazine that corresponds to the first tool spindle, and a second tool magazine that corresponds to the second tool spindle;
wherein, on the gantry, the first tool spindle and the second tool spindle can each be moved vertically in a first direction and horizontally in a second direction which is orthogonal to the first direction,
wherein the workpiece table is horizontally movable in a third direction orthogonal to the first direction and to the second direction, wherein the workpiece table is guided for movement in the third direction by a first longitudinal guide supported by the frame and by a second longitudinal guide supported by the frame,
wherein a first magazine opening is formed in the gantry and a second magazine opening is formed in the gantry, the first magazine opening and the second magazine opening being separated from one another in the second direction and being distinct from both one another and the gantry recess,
wherein a first end of the first tool magazine extends at least partially into the gantry within the first magazine opening, and wherein a second end of the first tool magazine, the second end being disposed opposite the first end of the first tool magazine, is located above the first longitudinal guide such that a first virtual vertical line intersects both the second end of the first tool magazine and the first longitudinal guide, and
wherein a first end of the second tool magazine extends at least partially into the gantry within the second magazine opening, and wherein a second end of the second tool magazine, the second end being disposed opposite the first end of the second tool magazine, is located above the second longitudinal guide such that a second virtual vertical line intersects both the second end of the second tool magazine and the second longitudinal guide.
