Outer sleeve raceways of ball bush have edges, which are the junctions between the straight portions and slopes, and the straight portions are only ground by internal grinding machine, hut the slopes can not be ground. Therefore premature flaking occurs because of balls recirculation over these edge portions, and hence the life of ball bush is comparatively shorter than expectation or theory. The purpose of this paper is the application of abrasive flow finishing for reformation of outer sleeve race way shape of the ball bush. This needs the development of an abrasive finishing device, for rounding out of the edge portions and also improvement of the surface texture of the raceway. The following conclusion is obtained- (1) The abrasive flow processing can result in rounding out of the edge to a suitable radius. (2) The surface texture of the raceway is also improved from 1.85μmRz to 0.24μmRz on an average after the processing.
