A machine tool system includes a machine tool including a processor to process a workpiece with a tool, and a bed on which the processor is mounted, a transport apparatus including two, left and right, legs spaced apart from the bed to transport the workpiece and feed the workpiece to the processor or discharge the workpiece from the processor, and a plate that connects the bed to the legs and is elastically deformable. The plate is upright such that a plate surface is aligned with a front-rear direction, and a connection portion of the plate that connects with the bed and a connection portion of the plate that connects with the legs are displaced in a front-back direction.

A machine tool having a machine frame, a first work spindle, a second work spindle, a first pivot carrier which is assigned to the first work spindle and which is swivel mounted around a first pivot carrier axis, a first workpiece table and a second workpiece table, and a second pivot carrier which is assigned to the second work spindle and which is swivel mounted around a second pivot carrier axis. The machine tool also includes a first workpiece table and a second workpiece table, the first pivot carrier and the second pivot carrier can each be moved from a first pivot position into a second pivot position, and the interference area of the first workpiece table and/or the interference area of the second workpiece table on the first pivot carrier protrude(s) outwards beyond the swivel area of the first pivot carrier transversely to the first pivot carrier axis.

A manufacturing cell comprises a machine tool that has a tool carrier carrying a tool unit and has two adjacent workpiece paths oriented in a longitudinal direction. The tool unit can be displaced relative to a machine bed of the machine tool in a transverse direction and in a vertical direction. At least one workpiece carriage per workpiece path can be displaced in the longitudinal direction along the machine tool. The tool unit can be displaced in the longitudinal direction relative to the machine bed and/or relative to the workpiece carriages. The tool carrier overhangs or projects beyond the workpiece paths. The individual workpiece carriage can also be displaced in the longitudinal direction along the workpiece supply. Furthermore, the workpiece supply has at least one lowerable or tiltable stop device per workpiece path.
