ABSTRACT:
Two pairs of crossed tool change arms are mounted adjacent to four spindles which are rotatably mounted on a common spindlehead. Each pair of crossed tool change arms is mounted on a common shaft which is rotatable and is movable along its axis and is positioned to simultaneously insert a pair of tools into or remove a pair of tools from the corresponding pair of spindles. A tool storage chain carrying a plurality of tool storage sockets is movably mounted on a frame in position to interact with the tool change arms which are operable to transfer tools from the tool storage sockets to the spindles and vice versa. Each tool storage socket is pivotally mounted for movement between a vertical storage position and a horizontal tool change position. Four tool storage sockets are pivoted from the vertical storage position to the horizontal tool change position for each tool change operation.
