<p>PISTON RING HONING A piston ring honing machine and method are disclosed wherein a stack of piston rings are face finished simultaneously by compressing the rings radially inwardly and into a generally circular configuration and retaining the outside diameter of that circular configuration by confining the compressed rings within a plurality of cylindrical drive rollers disposed about the rings. A honing tool is placed against the ring faces and the rings driven to rotate about the circle center by rotation of one or more of the cylindrical rollers. The stack of rings therefore moves relative to the honing tool to finish the ring face. The tool may be reciprocated in the direction of the cylindrical roller axes to move uniformly finish the ring faces.</p> |
