Abstract: Identical ring-shaped metal blanks are machined whereby each blank forms a plurality of identical components. The blanks are first machined on both sides, and then a stack of the blanks is clamped axially adjacent one another on an arbor. Tools machine the blanks for reshaping the blanks. One of the tools is a slitter which makes axial cuts through the stack to separate each blank into a plurality of components distributed around the axis.

Abstract: A progressive broaching apparatus comprising a base, an index table mounted on the base and defining a plurality of circumferentially spaced work stations, first and second columns mounted on and independently upstanding from the base, and first and second rams mounted on the first and second columns in overlying relation to respective spaced portions of the index table and operative to coact with the work stations in response to indexing movement of the work table to progressively transform an unfinished workpiece into a finished workpiece. A track is mounted on one of the columns to define a linear path extending between the columns in overlying relation to the index table and a trolley is mounted for movement on the track to facilitate the delivery of unfinished workpieces to the work stations and the removal of finished workpieces from the work stations.

Abstract: Apparatus for progressive blind broaching has an indexing table which carries a load station, a unload station and several tool stations. Broaches are mounted on the table at the tool stations. Rams on opposite sides of the table move workpieces up and down to be broached between intermittent indexing of the table. The load station has a workpiece holder to deliver unbroached workpieces to the rams. The unload station has a workpiece holder to receive broached workpieces from the rams. A transfer mechanism moves workpieces from a exchange depot at the rear of the table to the load station and moves workpieces from the unload station to the exchange depot. This transfer mechanism moves across the top of the table and does not occupy or obstruct any space along the sides or front of the table.

Abstract: A method and apparatus for progressive machining of blind spline workpieces which includes step-by-step moving of work holding stations on an indexing table with loading and unloading stations located adjacent the table between work stations. Axially in line with the work stations between indexes are multiple tool rams hydraulically powered to drive a broaching tool over or into workpieces to achieve progressive broaching as the work is indexed. The rams can be simultaneously activated or sequentially activated depending on the capacity of the hydraulic system.

Abstract: An automatic machine tool for sequentially machining a plurality of parallel surfaces on a plurality of work pieces, in which the work pieces are locked in position on an index table, and the surfaces machined in one operation are angularly disposed to the surfaces machined in a contiguous operation as a result of revolving the work pieces about the axis of the table.
