It is possible in reaming to produce the standard burrs for deburring tests, which have the desired controlled sizes. With the exit burrs of same height and different thickness, the deburring tests of vibratory finishing are carried out. The workpiece is a cylinder (φ30xφ10x10mm ) of High Carbon Chromium Bearing Steel (SUJ 2 in JIS, hardness 183 HB ). The existence of reproducibility of the burr is established. The burr height is nearly equal to the half of the remaval amount so that the burr can be considered as a roll-over burr. The base thickness, which is influenced by removal amount, feed and the interaction of them, has almost the same tendency as the neck thickness. The deburring time becomes shorter with larger media and heavier vibration, and rapidly increases as the base thickness becomes large. The surface of the workpiece becomes rougher with the deburring condition for shorter deburring time so that both the deburring time and the surface roughness must be considered for effective vibratory finishing.
