Document Type and Number:
WIPO Patent Application WO/1991/003343
Kind Code:
A1
Abstract:
In a multispindle automatic lathe which supports rotatably a plurality of spindles on a spindle carrier (52) which is supported indexably and rotatably by a head stock (51) and which is equipped with a single motor (20) for driving and rotating the spindles (55) in order to prevent mutual and spatial interference between the motor (20) and an elongated work-piece (W) when the elongated workpiece is machined, the present invention provides a multispindle automatic lathe characterized in that the axis of rotation of the spindle carrier (52) and the rotary output shaft (21) of the motor (20) are disposed on the same axis, means (56), (57) for transmitting the rotation output of the motor (20) to the spindles are provided and a through-hole (37) is formed in the stator (29) portion of the motor (20) so that it exists on the same axis as that of the center hole of the plurality of spindles (55).
