Provided is a nail grinder that includes a housing, a grinding member, a dust suction fan, a driving member, an ultraviolet lamp, and a first illumination lamp. The housing is provided with a grinding chamber, a dust collection chamber, and a fan installation chamber, which are connected in sequence. The grinding member is rotatably arranged in the grinding chamber. The dust suction fan is rotatably arranged in the fan installation chamber. The driving member is used to drive the grinding member and the dust suction fan to rotate. The ultraviolet lamp is arranged on the housing and used for emitting ultraviolet light. The first illumination lamp is arranged on the housing, and the light-emitting side of the illumination lamp is arranged to face toward the grinding member. The technical solution of this disclosure enriches the functions of the nail grinder.

A commercial nail application bench machine, kiosk, and process comprised of combinations of components and several steps. The commercial nail application machine includes a bench machine for multiple technicians with a bench structure for the technicians, a set of hand rests, a pair of UV/LED lights and dry/finish cure chamber, a pick and place for artificial nail placement with camera assist, an articulated motorized arm for nail preparation, removal and preparation, a colored polish and clearcoat application mechanism with cartridges for polish, clearcoat and adhesives, and a way to secure the pick and place and other components to the bench structure. This commercial nail application machine can be used for rapid and repeatable quality artificial nail placement by nail technicians. A process to use the commercial machine is included.

A five-in-one polishing head includes a blade portion and a handle portion. The blade portion is shaped like a cone having a concave or planar top end. Angle teeth, thin teeth, medium-thin teeth, and thick teeth are sequentially distributed in a conical polishing head according to the tooth density. The angle teeth are located at the top of the conical polishing head in a circle. The thick teeth are located at the end of the blade portion. The center of the end of the blade portion is axially welded and fixed to one end of the handle portion. The conical polishing head is provided with regularly distributed straight lines or oblique lines on a surface from the angle teeth to the thick teeth. The shape of a right-handed groove on the surface is inverted trapezoidal, and the shape of a left-handed groove is triangular.
