Claims

[Scope of utility model registration request]

Inside the main body of a cylindrical polishing device, one end is configured as an axially protruding shaft part connected to the inner diameter of the tube that is the object to be polished via a tube chuck, and the other end is connected to a drive source via a main drive shaft. A built-in shaft is fixed via a bearing in a direction perpendicular to the rotation axis, and a rubber abacus bead-shaped pulley and a bevel gear are integrally fixed to the built-in shaft, and both inclined surfaces of the rubber abacus bead-shaped pulley are fixed. The umbrella-shaped rubber pulleys of the external polishing shaft and internal polishing shaft are brought into contact with each other to transmit power, and the shaft ends of the external polishing shaft and internal polishing shaft are extended outside the main body of the polishing apparatus, and the shaft ends are connected to the respective ends of the polishing apparatus. An external polishing whetstone and an internal polishing whetstone are attached, and these whetstones are brought into contact with the inner and outer surfaces of the tube end of the tube to be polished so that they can be crimped, while the bevel gear, which is integrally fixed to the built-in shaft, is A tube end polishing device characterized in that it is connected to a main drive shaft via another bevel gear.
