Abstract
A machine tool having a turret head equipped with a plurality of multiple spindle units on the support stations thereof with the exception of one station rotatably supporting a tool spindle adapted to removably receive a tool, a tool storage magazine storing a plurality of 'single' tools, and tool changing apparatus for interchanging the tools between the tool spindle and the tool storage magazine. The turret head may be rotated to successively position one of the multiple spindle units or the tool spindle at an operating position that confronts with the workpiece supported on the worktable such that the multiple spindle unit or the single tool on a tool spindle performs the machining operation on the workpiece. With regard to the tool changing operation for the single tool, the tool changing means may automatically interchange a tool in the tool spindle positioned at the operating position with respect to a tool presented into a changing position where it is immediately above the operating position by the rotational indexing of the tool storage magazine. Furthermore, there is provided an elevating head which mounts thereon the turret head, the tool storage magazine and the tool changing means, and also causes the tool storage magazine and the tool changing means to travel in a body relative to the workpiece such that the tool changing operation for the single tool may be initiated immediately when and where the machining operation is halted.
