ABSTRACT:
A machine tool includes an indexing device for indexing a spindle to a predetermined angular position for engagement between a key member disposed upon the spindle and a key-way disposed upon a tool to be used. When either the tool, to be used next, upon a tool storage magazine, or a used tool, held upon the spindle, is a tool utilized for heavy cutting, the indexing device is operated before the tool change operation is performed. On the other hand, when the tool to be used next, and the used tool, are both tools utilized for light cutting, the tool change operation is performed without operation of the indexing device.
