Field of the Invention [0001] The present invention relates to a polishing apparatus for polishing a blade of a cutlery such as a knife, a scissors or an ax, and more particularly to a blade polishing apparatus for polishing a blade of a blade using a circulating polishing belt.

Knives, such as knives, scissors, sickles, axes, etc., are worn when used for a long time and need to be sharpened again for reuse.

However, cutlery such as knives and scissors has various uses ranging from general items used at home to specialized fields such as peacocks or beauty and beauty. In addition, knives and scissors used in professional fields such as peacock, beauty, and beauty are expensive and require high precision of the product.

In particular, ordinary knives and scissors used at home are rarely used for grinding and reusing abrasive blades. However, expensive knives and scissors used in the field of specialty are frequently used when the blades become dull.

In general, however, such a polishing operation requires a considerable amount of time and a high degree of skill because the grinding operation is a method of reciprocating the grinding wheel while spraying water with the grinding blade. If you can not find a skilled worker or are chased in time, you have to do your own polishing, but because of the high risk of a safety accident, you will make an uneconomical choice to buy a new cutlery.

On the other hand, in the case of polishing the surface of the abrasive wheel rotating at high speed by abutting the abrasive wheel, there is a problem that the abrasive wheel is expensive and a considerable cost is incurred when the equipment is initially purchased and the abrasive wheel is worn out .

In addition, since the blade must be ground with the blade laid at an appropriate angle on the surface of the grinding wheel rotating at a high speed, there is also a problem that the precision of polishing is greatly influenced by the skill of the operator.
