In general, recently, electronic devices are used as parts that visually provide various information using liquid crystal panels made of glass materials of various sizes. Liquid crystal panels made of glass are essential for various products such as

In order to grind a large amount of flat glass used for these electronic devices

Patent No. 1389924 “Eye surface polishing device for flat glass” and Patent No. 1964565 “Cell phone glass edge surface polishing system”, which the applicant applied for and registered, have been developed so that flat glass polishing can be performed in large quantities.

This polishing and polishing apparatus is equipped with a brush-shaped abrasive drum to polish flat glass, and the drum shape is provided in the longitudinal direction according to the size of the glass stack, and is replaced with a new product after the polishing process for a certain period of time.

However, in the brush of the conventional grinding drum, irregular wear of the brush occurs due to friction in the polishing process with the edge surface of the flat glass. It is not possible to uniformly maintain the overall polishing quality of the edge surface of the thin flat glass, so after using it for a certain period of time, it is replaced with a new one.

In order to solve this problem, the polishing quality is kept constant by replacing the consumable abrasive drum faster than the original use cycle, and there is a drawback in that the polishing cost increases due to early replacement. There is a drawback in that the entire grinding drum must be discarded.

Prior art related to the maintenance of brush quality of a polishing apparatus used for polishing flat glass of such electronic devices has been disclosed.
