Abstract: A tool changer mechanism for a vertical spindle machining center has a remotely positioned tool storage magazine. Tools are transferred between the magazine and the spindle by a tool transfer assembly which is mounted for reciprocating sliding movement along the side of the machining center. The tool transfer assembly incorporates a pivotally mounted support adapted for vertical movement and a rotatable transfer arm, having two grippers, carried by the support.
