A multi-spindle machine tool has a frame, a work spindle carrier and its rotatable work spindles indexably mounted on the frame, and a main drive shaft arranged to drive the work spindles. A tool slide is mounted on the frame for movement towards and away from the spindle carrier, and movement of the slide and indexing of the carrier are controlled by a cam shaft. A drive input shaft transmits drive through a gear train from the drive input shaft to the main drive shaft and the or each cam shaft, the gear train being mounted in a readily accessible position on the frame so that gears thereof can be readily changed, and the or each cam shaft being arranged at a side of the frame so that said cams are readily accessible for changing. |
