<p>PROBLEM TO BE SOLVED: To provide a tool exchange method of a machine tool which enables a long tool to be exchanged by attaching to or detaching from a spindle while achieving space saving and low costs.SOLUTION: A machine tool moves a long tool 2 which is provided so as to be detachably attached to a spindle 106, and a workpiece 1, which is placed on a table 102 through a pallet 107A, relative to each other in a three-dimensional manner to perform processing to the workpiece 1 with the long tool 2. In a tool exchange method of the machine tool, a pallet 107B, on which the long tool 2 is placed, is transferred by an unmanned carrier 200 for transferring the pallet 107A so as to be disposed on the table 102 of a machining center 100. Then, the pallet 107B and the spindle 106 are moved relative to each other in a three-dimensional manner to attach the long tool 2 to the spindle 106.</p> |
