  As an abrasive for forming a polishing layer formed on the surface of the brush abrasive body of the present invention, an abrasive used for sandpaper, a file, a ceramic polishing cloth, a grindstone, or the like can be used. In addition to the adhesion of the abrasive, it is also effective to provide fine irregularities on the base material that fixes the abrasive. In many cases, a brush polishing body forms a polishing layer on a contact surface between a flat plate and a cylindrical surface.

The timing when the brush polishing apparatus makes the brush polishing body contact the tip of the bristles of the rotating brush can be performed regularly or irregularly. In the embodiment, the rotating brush is brought into contact with the brush abrasive for 5 seconds after rotating for 15 seconds. This can be controlled by an electronic circuit using a timer or by computer software.
Further, the movement of bringing the brush polishing body into and out of contact with the rotating brush can be performed periodically using a spring force, an electromagnetic attraction force such as a solenoid, or a rotating cam plate. Although there are various operating mechanisms, it is preferable to use a spring and an electromagnetic solenoid as in the embodiment because of simple control and structure.

  Further, the length of the bristles of the rotating brush is preferably the length of the bristles that causes the bristles to come into contact with the surface of the accessory as shown in FIG. With this length, the tip of the brush bristles pierces the corners of the irregularities on the surface of the accessory, scraping off the deposits, and the elastic force due to the bending of the brush bristles creates a force to repel.

  The pair of opposed rotating brushes is typically a rotating brush arrangement in which the medal transport path faces in the vertical direction in the horizontal direction, but the medal transport path may be vertical and inclined. Rotating brushes facing left and right in the horizontal direction may be used, or the facing direction may be inclined.

  In addition, the peeled material collecting device can adopt a structure of a suction type vacuum cleaner (a type in which dust is accommodated in a filter bag and a type in which dust is captured by a cyclone and collected in a small chamber). The air suction port sucks debris such as dust, particles, debris, brush shavings, etc. scattered and floating with the air between the opposing rotating brushes and the surrounding air, and stores them in the filter bag or in the cyclone chamber. If a large amount is contained, it is better to discharge from the filter bag / compartment.
