ABSTRACT:
A machine tool with an automatic tool changer in which a new tool is removed from a self-indexing storage magazine and loaded into a spindle journaled in the frame of the machine. A tool changer mechanism comprises a carriage slidably mounted on the frame for movement substantially parallel to the axis of the spindle and a boom pivotally mounted in the carriage. The boom has first and second telescoping transfer arms for receiving and conveying tools to the spindle and the magazine. The transfer arms are substantially coplanar and perpendicular to the axis of the spindle but displaced relative to each other at a fixed acute angle. Motors are provided for sliding the carriage to reciprocate the boom in a direction substantially perpendicular to the plane of the transfer arms and substantially parallel to the axis of the spindle, as well as for pivoting the transfer arms in a plane substantially normal to the spindle axis whereby each of the transfer arms can be positioned to engage a tool at the storage magazine and at said spindle.
