Progressive blind spline broach machine and method

摘要

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.
