Abstract
In the barrel finishing, the different kinds of compounds resulted in the different volumes of roughness and polishing removal. Using the sodium carbonate of less polishing power, the volume of roughness removal decreased, and the sodium oleate of polishing power, the volume of roughness removal was twice as much as that of sodium carbonate and the polishing removal remarkably increased. By addition of the abrasive, the surface became uneven and the volume of roughness and polishing removal increased. The volume increased with an increase of the number of revolution of barrel. The use of the big media greatly increased the volume of roughness removal. When 2% sodium stearate was used as the brightness compounds, even the slight unevenness was easily removed.
