PURPOSE: A rotary tank for grinding a metal workpiece is provided to increase torque of the rotary tank and frictional coefficient between the metal workpieces and to increase work efficiency. CONSTITUTION: A rotary tank for grinding a metal workpiece comprises a pair of jaws, a clamping band(22) and a flange part(11). Facing surfaces of a pair of jaws is declined. The clamping band made of a metal ring is inserted into the circumference of a cover in order to seal the circumference of the cover and upper body. The flange part is in accord with the external diameter of the cover. The inside wall of the body is polyhedron increase collision between the metal workpieces and polishing particles. |
