Abstract

1486422 Multi-spindle lathes WICKMAN MACHINE TOOL SALES Ltd 28 Nov 1974 [6 Dec 1973] 56565/73 Heading B3T In a multi-spindle lathe in which a plurality of work spindles 16 are rotatably mounted in an indexable spindle drum 14, electromagnetic means are provided on each spindle to permit engagement and disengagement of the drive to the spindle, the electromagnetic means is incorporated in clutch and brake mechanisms on the spindle which are respectively connected to a source of electrical supply through wiring 26 extending through a drive tube 29 coaxial and indexable with the spindle drum 14 the tube carrying a rotary electrical distributer 27 which provides the electrical connection between the wiring and the supply source. The electromagnetic means in the clutch mechanism is mounted in a ring surrounding each respective spindle and secured to the spindle drum and is constituted by coils occupying axially positioned annular grooves in the rings.
