ABSTRACT:
A center column machine assembly having a hydraulic manifold formed by a one-piece outer ring attached to the stationary part of the center column and a one-piece inner ring which is indexed with the work table. The two rings have overlapping surfaces defining an annular manifold passage around the column and between the two rings. The fixed ring has a port for receiving or discharging fluid under pressure, and an internal passage connecting the port to the annular manifold passage. The indexable inner ring has an outlet port suited for connection to a work fixture mounted on the work table. The indexable ring has an internal passage connecting the manifold passage to the outlet port so that the work fixture can be hydraulically actuated in a series of rotated work positions around the column.
