ABSTRACT:
A multi-spindle lathe includes a pair of main spindles, a first spindle being located on one side of a main spindle head and a second spindle being located on an opposite side of the main spindle head. A supporting shaft extends through the main spindle head, and the head is selectively engageable with a head stock. The head stock is provided with an assembly for rotatably driving either of the main spindles when such spindle is positioned below the main spindle head, in order that a workpiece can be operated upon, while the spindle is positioned above the main spindle head in order for a workpiece to be attached or detached.
