Abstract
The present machine tool is constructed for an automatic tool exchange and includes a double column (11, 12) in which a spindle unit (15) and a tool magazine (22) are separately guided for moving jointly. A grapple claw mechanism includes an angular double claw. These features satisfy the hitherto contradictory requirements for a minimal idle time for the tool exchange and for a high machining accuracy by the elimination, among others, of the positioning tolerance.
