摘要： PROBLEM TO BE SOLVED: To realize a barrel polishing method which shortens a polishing time and polishes the surface of a workpiece to a super-smooth surface state. SOLUTION: The barrel polishing method comprises: a roughly polishing step S1 of providing, as a barrel polishing apparatus, a fluidized barrel polishing apparatus including a polishing tank 1 constructed so that the interior thereof can be washed, introducing spherical media having a smooth surface, abrasive grains which are ground with the progress of polishing, a compound, and water into the polishing tank 1, and polishing a workpiece; a washing step S2 of, after the roughly polishing step S1, supplying water into the polishing tank 1 to remove, by washing, the abrasive grains, the compound, and powder produced by abrasion of the workpiece and media remaining within the polishing tank 1, discharging the abrasive grains, the compound, and powder produced by abrasion of the workpiece and media to the outside of the polishing tank 1, and allowing the washed workpiece and media to stay within the polishing tank 1; and a smoothly polishing step S5 of, after the washing step S2, introducing fresh compound and water into the polishing tank 1 and polishing the workpiece.

摘要： PROBLEM TO BE SOLVED: To provide a method for polishing a hard metallic material, which performs both a smooth polishing action for reducing the surface roughness of a work made of the hard metallic material and a grinding action for adjusting the outline dimensions of the work, can increase a polished amount (=charged amount) of works for each batch charged into a polishing tank, and can increase productivity by eliminating a sorting step for work and media. SOLUTION: This method for smoothly polishing a hard metallic material includes a polishing step A16 for polishing a work without using media by charging the work, abrasive grains A crushed according to the advancement of the polishing, and water in the polishing tank 1 using a flow barrel polishing device in a polishing device and a washing step A17 for flushing the polishing tank by rotating a rotating disk 4 after washing water is supplied into the polishing tank 1 and stored in the polishing tank 1, and discharging the abrasive grains A and water used for polishing and polishing waste to the outside of the polishing tank 1 together with the washing water to remain only the washed work in the polishing tank 1.

摘要： PROBLEM TO BE SOLVED: To provide a fluid barrel polishing device coping with a request for narrowing a sliding gap formed between an inner peripheral surface of a fixed container and an outer peripheral end face of a rotary disk. SOLUTION: In the fluid barrel polishing device, a polishing container is formed of a fixed container and a rotary disk, which is arranged on a bottom of the fixed container, has a sliding gap 24 between the inner peripheral surface of the fixed container and the rotary disk, and rotates horizontally. The fixed container 14A has a cylindrical liner 18 on the inner peripheral surface of a vertically cylindrical rigid body 16A, and the rotary disk 15A has a dish-shaped liner 22A on an upper surface of a dish-shaped rigid body 20A. A thermal expansion relief section (an opening) 38 is prepared on an outer peripheral side of the cylindrical liner 18 in a position corresponding to the sliding gap 24, and a circular diameter expansion restraining rigid body 42 is exchangeably arranged on an outer peripheral part of the rotary disk 15A so as to form the sliding gap 24 by an outer peripheral end surface of the diameter expansion restraining rigid body 42.
