Abstract
A machine tool comprises a travelling column, a spindle stock to be displaced on the travelling column, and a tool magazine. Toolholders are stored in the tool magazine and may be individually conveyed into a transfer position within the tool magazine. Two gripper arms serve to interchange the toolholders between the transfer position on the tool magazine and a working position in the spindle. The orientation of the toolholders during interchanging is maintained. The gripper arms are separately mounted on the spindle head and can be pivoted simultaneously and in opposite directions along locus curves. The gripper arms have grippers to hold the toolholders during the interchanging between the transfer position and the working position. The transfer position and the working position lie in a common vertical plane. The transfer position is located in the area of the travelling column front side facing toward the spindle stock. The tool magazine extends from a rear side of the travelling column through a tunnel in the travelling column to the transfer position. In the area between the positions the locus curves run at a lateral distance from the vertical plane.
