摘要： A machine for finishing eccentric shafts includes a flow-through quick change arbor with axially spaced radial ports. Hollow adapter hubs are spaced along the shaft in register with the ports. Axial spacing is obtained with cylindrical spacers and discs on each side of each hub. A nut on one end of the shaft clamps stacked hubs, discs and spacers together for rotation with the shaft. Each hub supports two side-by-side finishing tools, each of which includes a ring from which the finishing material extends in a radial array. Each hub on its face includes a set of diametrically opposite bayonet slots which interfit with drive lugs on the inside of the rings. The slots extend in both circumferential directions from the axially extending entrant portions with the ends engaging the lugs for rotation in either direction while providing ease of mounting and replacement. The entrant portions on each side of the hub are aligned and connected so that a tool ring may be mounted from either side of the hub. The hub includes radial ports between the rings so that fluid may flow from the shaft through the hub and between the side-by-side tools on the hubs. The sides of the rings of the tools may be provided with indentations to facilitate this flow directly to the tool working face, which in turn provides an improved quality of finish and longer tool life.
