<p>A tool changing unit (13) moves between a magazine position (Pm) and a changing position (Px) to transfer a tool (2). A machine tool (1) has a plurality of tool changing positions (Px). One of the tool changing positions (Px) is selected in advance for changing the tools (2) next time. The tool changing unit (13) and the tool (2) mounted on a tool spindle (15) move to the selected changing position for changing the tools (2) in the selected changing position. Accordingly, the tool changing unit (13) and the tool spindle (15) move respective short distances for changing the tools, thereby shortening the non-machining time of a machine tool combined with the automatic tool changer (10).</p> |
