ABSTRACT:
This invention makes it possible to freely exchange an attachment 20, to which is connected a flexible cable 21 used as an energy supply line and a signal line, on an end surface of a ram 13 of a spindle head of a machine tool having a plurality of control axes. Support means 26a, 26b, and 28 supports the cable in such a manner that this cable 21 can follow the motions of the spindle head. A conveyor means conveys the attachment between an attachment/detachment position at the end surface of the ram 13 and a position at which the attachment 20 is stored, with the cable 21 still connected thereto. The automatic attachment exchange apparatus of this invention automatically exchanges attachments while cables, such as energy supply cords and signal lines, are still connected to the attachments, thus resolving the inconvenience of connecting and disconnecting cables.
