ABSTRACT:
A machine tool is provided with an exchange arm for automatically exchanging tools between a tool spindle and a tool magazine. A drive key and a detent pin protrude respectively from the tool spindle and each of the tool storage portions of the magazine and are engageable, with a predetermined play, with a key-way of each tool. A fine indexing device has a rotatable cam drum on which a first cam segment is formed for indexing the tool spindle to a predetermined angular position following a coarse indexing operation by a coarse indexing device. A second cam segment is further formed on the cam drum to rotate the tool spindle more than the play from said predetermined angular position after a fresh tool is inserted into the spindle, so that a positive engagement between the drive key and the key-way of the tool can be achieved.
