A machine tool for working elongated rod-like materials in rotation, particularly an automatic screw machine capable of working thin and long materials with a high degree of accuracy comparable to that of a headstock moving type automatic screw machine without involving any error in the indexing of the cutting tools for the work. The tool stand is reduced in weight, and movable along the longitudinal axis of the work, so that the machine is easy and inexpensive to manufacture. |
