Title: Barrel polishing method
Inventor: ONO TAKAYUKI
IPC: B24B31/02
Filed: 2000-03-07
Abstract: PROBLEM TO BE SOLVED: To provide a good polishing condition. SOLUTION: A barrel polishing vessel B is composed of a cylindrically formed fixed bath 10 and a rotative vessel 11 concentrically and rotatably arranged on the bottom part of the fixed vessel 10. When a workpiece w is polished, the entire barrel polishing vessel B is kept in a form tilted at a predetermined angle with respect to the vertical axis, and the rotative vessel 11 is turned in that form. Then, the mass m in the vessel is biassedly present in the lower side of the tilt so that a low-speed region L is formed and on the contrary, a high-speed region H where the layer of the mass m is thin is formed on the upper side of the tilt. In a transitional border part from the high-speed region H to the low-speed region L, the flow of the mass m comes into a turbulence state.  Thereby, the workpiece w can surely be involved in the low-speed region L, and the workpiece w is rubbed with polishing material or the like in a resident region, so that a desired polishing condition can be provided.
