The invention is directed to an indexing attachment for a numerically controlled milling machine, comprising an indexing spindle rotatably supported in the casing for receiving a workpiece chuck, a bottom plate for fixing the casing on a worktable, and clamping means for fixing the indexing spindle in the various indexing positions. The indexing attachment is to be of simple and inexpensive structure and intended to permit--without any drive means of its own--programme-controlled indexing operations and thus milling steps along five axes. To this end the indexing spindle (10) of the indexing attachment (8) is adapted to be coupled with a driver (4) mounted on a part (2) of the milling machine and to be driven by programme-controlled motions of the milling machine. The end face of the indexing spindle (10) may be fixedly connected to a plate (12), said plate being formed with an eccentrically located recess (13) for engagement with the driver (4), which driver may be in the form of a pin capable of being clamped in the main spindle (3).
Indexing apparatus for a numerically controlled milling machine having a main spindle (3) mounted to be movable along a first axis and having means for holding a first coupling element (4), a worktable (6) mounted to be movable along a second axis transverse to said first axis, a rotary table (7) mounted for rotation upon said worktable, and a casing (9) fixed to said rotary table comprising an indexing spindle (10) having a shaft rotatably mounted in said casing, a plate (12) fixed to the shaft of said indexing spindle and having a second coupling element (13) and means for periodically joining said first and second coupling elements in accordance with program-controlled motions of said milling machine to cause predetermined angular movements of said indexing spindle.
