Description

Polishing Apparatus for Watch Band}

The present invention relates to a clock band polishing apparatus, and more particularly, to a clock band polishing apparatus that introduces a vertical grinding concept rather than a horizontal concept in clock band polishing, and enables the production of angled bands using special jig and abrasive. It is about.

In general, a watch band is divided into a metal band and a non-metal band, and the metal band includes a mesh band made of a plurality of metal wires in a mesh shape and a block band in which link material is connected in a link form. Nonmetallic bands include leather bands and synthetic bands.

Among them, the metal band, which is a metal band, has no nodes and is freely stretched to some extent, but is not used well because of limited design changes appearing outside. Recently, block bands that can freely adjust length and change designs are mainly used.

In addition, metal bands are usually used to plate the surface of the material (plating (approximately 3-10 microns)) in order to enhance the decorative effect, or replace each node of the band with a gold plate.

In addition, a high-quality band may be polished in order to gloss the manufactured band surface.

Metal bands can be polished by using profiles (profiles) to make and polish the band (generally bright or matt), or press forging to make bands and general polishing.

However, in the conventional clock band manufacturing process of the angled band, in the polishing process, the angled band is horizontally applied to the outer circumferential surface of the rotating abrasive to be polished. It was impossible to manufacture.

The present invention has been invented to solve this problem in view of the above-mentioned problems, and in the polishing of a watch band, the introduction of a vertical grinding concept rather than a horizontal concept and the polishing of an angular watch band capable of producing an angular band using a special jig and abrasive.
