The completed product consists of the steps of forming a resist image on the metal plate to cover the area that will become the protrusion of the file on the surface of the metal plate, and then etching the exposed metal surface and applying the file to the surface of the metal plate. This method of manufacturing a file comprises a step of forming a protrusion, and a step of peeling off a resist film from a metal plate on which the protrusion of the file is formed.

Next, as shown in the second figure, on the photosensitive resin layer 2, a large number of micro circular dot-like transparent parts with a diameter of 0.1 to 3 sides are randomly formed on the black light-shielding surface, either independently of each other or in a series of several pieces. Place the arranged original plate 3 on top. Next, the two are brought into close contact using a vacuum printing frame or the like, and then a light beam rich in ultraviolet rays from a xenon lamp or the like is irradiated to sharpen the two, followed by development to form a resist image 4 consisting of a large number of resist dots. After that, as shown in the fourth figure, the back side of the metal plate 1 is coated with corrosion-resistant varnish (
After covering the metal surface with resist image 4 (Shellard varnish) 5, the exposed metal surface is sprayed with an etching solution such as ferric chloride solution under etching conditions that increase side etching. After etching to form Mt. Fuji-shaped, mushroom-shaped, or needle-like protrusions 6, as shown in the sixth figure,
By peeling and removing the resist film, it is possible to obtain a fine file 7 in which a large number of protrusions 6 are randomly arranged in a densely packed state, either independently of each other or in a series of several protrusions.

In the present invention, instead of using a black light-shielding surface as an original in which a large number of tiny circular dot-like transparent parts are randomly arranged, the black light-shielding surface has a large number of star shapes, diamonds, triangles, squares, polygons, etc. A resist image is formed using an original plate in which transparent portions of minute dots of square or other shapes are arranged randomly or independently of each other, and then etched to form stars, diamonds, etc. A file may be formed in which triangular, quadrangular, polygonal, or other shaped protrusions are randomly arranged, either independently of each other or in a series of several protrusions.

In addition, as an original plate, circles, stars, diamonds, etc. can be printed on a black light-shielding surface.
A resist image is formed using an original plate in which minute dot-like bald areas in triangles, squares, polygons, and other shapes are arranged in a constant array, and then etched to form circular, star-shaped, and
A file may be formed in which protrusions of a rhombus, triangle, square, polygon, or other shape are arranged in a constant array. Furthermore, a resist image is formed using an original plate in which a large number of thin linear transparent parts are arranged in parallel on a black light-shielding surface,
Thereafter, etching may be performed to form a file in which a large number of thin line-shaped protrusions are arranged in parallel. Next, in the embodiment of the present invention described above, etching is performed under etching conditions that cause large side etch, but the present invention is not limited to this, and etching is performed under etching conditions that cause less side etch. You can also do it at the base.

Alternatively, the resist image 4 may be formed by spraying a paint made by diluting a corrosion-resistant varnish (shellac varnish) with thinner onto the metal plate surface. As described above, according to the present invention, a resist image consisting of an aggregate of a large number of minute dots or an aggregate of a large number of fine lines is formed on a metal plate, covering the area that will become the protrusion of the file on the surface of the metal plate. By setting and etching, it has a finer grain than a secondary file, and can be used to smoothly grind or even polish metal, glass, ceramics, wood, plastic, leather, nails, pencil lead, paper, etc. It can manufacture files, files for polishing pencil lead, files for polishing leather, files for nail polish, etc.

Further, according to the present invention, it is also possible to manufacture a file similar to a conventional file by providing a resist image with a coarse pattern on a metal plate and etching it. According to the method of the present invention, files with various grain patterns can be formed as mentioned above, so files with various polishing effects can be manufactured. Furthermore, by the method of the present invention, not only files for grinding or polishing, but also mimeograph files can be produced, and as mentioned above, files with various grain patterns can be formed, so that various mimeograph effects can be achieved. Mimeograph files can be manufactured.

Next, the original plate (diameter 0.5 mm on the black light-shielding surface) is placed on the photosensitive resin layer.
An original film (with circular transparent parts on the sides arranged randomly) was adhered to the film, and it was baked with a xenon lamp for 6 inkstone sands. At this time, the illuminance of the original film surface is 8 to 10
It was a good look. After baking, water is sprayed to create a phenomenon in which a large number of approximately 0.5

After rinsing with water, the resist film is dissolved and peeled off by immersion in a 10% caustic soda aqueous solution of 90-95%, and after rinsing with water, it is dried to form Mt. Fuji-shaped or needle-shaped protrusions arranged densely and randomly. I was able to obtain a fine-toothed file. This file is finer than conventional special steel plates with indentations made by pressing or cutting, so you can use this file to cut metal, glass, ceramics, wood, plastic, leather, nails, pencil lead, and paper. I was able to polish the surface of things smoothly. Example 2 SKS-2 cutting steel (0.7 ribs thick) was prepared, the surface was made smooth, and Nissan Metalex (manufactured by NOF)

The silk screen ink used was NAZ-DAR2.
06 (manufactured by NAZ-DARCO.8 (USA)), the silk screen plate was 200 lines/inch and had a normal tension. After printing, 8 pieces were heated and dried in an oven at 0±5° C. for 18 minutes. After that, the back side of the SKS-2 board was completely covered with an electrically insulating resin (Scheratskvarnish), and a ferric chloride solution (
45-470, 38-40 technique') to etch the exposed metal surface, and due to the side etching action, etching also occurs from the boundary between the printed ink image and the exposed metal surface toward the center of the printed ink image. After progressing to 0, the contact area between the printed ink image and the metal surface, which was initially on the 0.5 side, gradually became smaller, and when the contact area between the two became on the 0.1 to 0.2 side, the etching work was started. It stopped. 90-9500 after washing with water

Nickel electrodeposition was carried out for 20 minutes in a vacuum cleaner to improve the rust and corrosion prevention effects. After washing and drying, we were able to obtain a file with fine cross-shaped protrusions oriented in different directions and arranged randomly, and the entire surface was covered with a nickel plating layer. This file has a finer grain than conventional products that are made by making indentations on special steel by pressing or cutting, and can be used to grind or polish metal glass, metal glass, etc.
It was able to smoothly polish the surfaces of ceramics, wood, plastic, leather, nails, pencil lead, paper, etc. Example 3 O SUS-304 stainless steel (thickness 0.5
