Specifically, the cutting bit 11 moves along the edge of the nail body where the cuticle is formed, and cuts the cuticle. At this time, the cutting bit 11 cuts the portion where the nail fold and the cuticle are connected, so that the cuticle portion located on the nail body side may remain. Therefore, about 90% of cuticles are cut, and about 10% of cuticles may remain. That is, the part with the largest diameter of the cutting bit 11 contacts the cuticle and cuts the cuticle along the cuticle line through friction, but the cuticle of the cuticle line that does not contact the part with the largest diameter of the cutting bit 11 Cuticles can be cut so that they remain.

In the cuticle removal step (S20), as shown in FIG. 11, the cuticle remaining in the cuticle cutting step (S10) and the loose cuticle may be simultaneously polished using the sanding bit 12.

Specifically, the sanding bit 12 may simultaneously grind and remove remaining cuticles and loose cuticles while moving from the nail body to the nail fold side. That is, by using the sanding bit 12 to push the cuticles remaining on the nail body toward the nail fold, the remaining cuticles and loose cuticles can be removed at the same time. At this time, the burrs may also be removed from the nail fold portion in contact with the sanding bit 12 .

In the cuticle arranging step (S30), the loose cuticle remaining on the sideline can be removed while the care bit 13 is moved along the sideline of the nail body.

In the callus removal step (S40), the callus bit 14 can be used to polish the callus formed on the nail fold and nail wall to remove the callus.

In the trimming step (S50), the nail fold and the cuticle wall formed on the nail wall may be polished using the polishing bit 15. As described above, if the cuticle is removed in a state in which the cuticle was thick before the cuticle removal, the nail fold in a state in which the cuticle is removed may be lifted from the nail body. At this time, the nail fold may be pressed toward the nail body by the polishing bit 15 so that the nail fold and the nail body come into close contact.

Although representative embodiments of the present invention have been described in detail above, those skilled in the art will understand that various modifications are possible to the above-described embodiments without departing from the scope of the present invention. . Therefore, the scope of the present invention should not be limited to the described embodiments and should not be defined, and should be defined by not only the claims to be described later, but also those equivalent to these claims.
