Abstract: A machine tool for multiaxial machining of a workpiece in a chuck. Both horizontal and vertical motion are provided. Even greater efficiency can be achieved by properly positioning tool magazines and providing at least two work stations in adjacent relationship.

Abstract: A tool changing assembly for program controlled milling and drilling machines comprising a vertically movable knee-type unit for the work table, and a vertical milling head. The tool changing assembly includes a power-driven pivotable mounting which is arranged in the form of a bracket for pivoting movement about a vertical axis on a column mounted on the knee-type unit laterally spaced from the work spindle of the milling head. The free end of the bracket has gripping pliers mounted thereon for pivoting movement about a likewise vertical axis, the pivoting movement of the gripping pliers being opposite to the pivoting movement of the bracket and being derived therefrom.

Abstract: A tool changing device for program-controlled universal milling and drilling machines as well as machining centers. The device comprises at least one gripper movable in plural axes between a tool magazine and the horizontal and vertical work spindles respectively. The gripper is secured to a program-controlled motor-driven support and transfers the tools from the transfer position of the tool magazine to the horizontal or vertical work spindle. In accordance with the disclosure a bracket is mounted on a cross member secured to a sidewall of the machine frame, the bracket being axially movable and pivotable within predetermined limit positions. A bent or cranked support is mounted on the free end of the bracket for rotation therewith and carries a 90.degree.-rotatable cross-arm including the gripper.
