Abstract
A machine tool having an automatic tool changer for interchanging cutting tools between the machine spindle and a tool storage wheel. The shanks of the tools are fitted in special "pot-type" holders which support the tools in assigned positions on the storage wheel. A shuttle extracts a selected tool and its holder from the storage wheel and transports them to an interchange position adjacent the machine spindle. At the interchange position a newly selected tool is extracted from its holder and is inserted into the spindle while the previously used tool is inserted into the holder in which the newly selected tool was delivered to the interchange position. The old tool is then returned in this holder to its assigned position on the storage wheel.
