Abstract
A tool changing device for a lathe of the type having a base structure with parallel column guides for longitudinal movement of a tool storage and changing device. The tool changer disclosed is a generally circular tool magazine, a cross slide member mounted on the longitudinal guide means of the lathe, the magazine surrounding one of the longitudinal guides. The tool changer is rotatably movable to select one of a plurality of tools circularly disposed thereon to bring the desired tool to a position adjacent the axis of rotation of a workpiece supported on the lathe. When the selected workpiece is in position, the apparatus establishes a rigid and direct connection between the selected tool holder and the lathe with the tool holder remaining on the magazine. Seals are provided to prevent turnings and other dirt from entering the tool changing mechanism.
