In an embodiment, a machine tool includes two fixed modules and two movable modules each of which having a main spindle, a headstock, and a tool post being integrally formed, and a bed on which these are installed. The movable modules are provided on the bed to be movable in the Y-axis direction, the fixed modules are fixed on the bed on the opposite sides of the these movable modules, and a recess is provided next to the fixed module, the recess being formed by cutting out the bed. The movable modules are movable such that the axis lines of the main spindles of the movable modules are aligned with the axis line of the main spindle of the fixed module or the fixed module. The movable module is movable to the opposite position of the recess.

A manufacturing system is proposed, said manufacturing system having a plurality of machine tools for performing chip-forming working operations on workpieces and comprising a plurality of work sequence devices, each of which comprises at least one machine tool, wherein the work sequence devices are sequentially arranged and different chip-forming workpiece working operations are performed in different work sequence devices, and comprising an automated transport device for transporting workpieces within and between work sequence devices, wherein at least one branch is provided in which a plurality of work sequence devices are arranged, wherein devices for non-chip forming workpiece treatment are arranged outside of the at least one branch.
