[PROBLEMS] To provide a machine tool which enhances work production efficiency while achieving compactness of the whole machine. [MEANS FOR SOLVING PROBLEMS] In a machine tool (100) comprising a plurality of main shafts (111) and a plurality of tool rests (120), each tool rest (120) is arranged on the end face side of the main shaft (111), at least one of two adjoining tool rests (120) is provided with a work holding means (130) and the moving range of the tool rest (120) having the work holding means (130) is set to such a range that both main shafts (111) and the work holding means (130) reach a position where they face each other. Moving range of the tool rest (120) corresponding to the adjoining main shaft (111) is set to overlap the moving range of the tool rest (120) at least partially so that the tool rest (120) can slide to a position for avoiding mutual collision of the tool rests (120).

WORKPIECE SUPPLY/CONVEYANCE DEVICE AND MACHINE TOOL WITH THE WORKPIECE SUPPLY/CONVEYANCE DEVICE
A workpiece supply/conveyance device that can, smoothly and in a short time, remove a workpiece from and supply a workpiece to the spindle. A workpiece holding section of one of arms has an unprocessed workpiece holding section (29) for holding an unprocessed workpiece and also has a processed workpiece holding section (21) for holding a processed workpiece. When the arms are rotated in one direction, each of the arms is moved to the following positions: an unprocessed workpiece loading position (III) at which the unprocessed workpiece holding section receives an unprocessed workpiece, a standby position (IV) at which the unprocessed workpiece holding section is in a standby state while holding an unprocessed workpiece that is to be processed next, a workpiece delivery/reception position (I) at which a workpiece is delivered and received between a workpiece processing device, the unprocessed workpiece holding section, and the processed workpiece holding section, and a processed workpiece unloading position (II) at which the processed workpiece held by the processed workpiece holding section is unloaded.
