グー等の前工程工具としても自動化が可能である．《Prior Art》 Conventional files, whether manual or electric, only involve reciprocating or rotating a rod-shaped or plate-shaped file, so they rely on the dexterity of the worker to handle curved surfaces. It wasn't there. Therefore, unmanned systems are extremely difficult and must rely on human power. 《Problems to be solved by the invention》 Recently, a wide variety of surface finishing techniques have been developed for flat surfaces, from super finishing to sand finishing, but these techniques can only be applied to curved surfaces and mixed surfaces of flat and curved surfaces. I can't find anything effective, including paris removal. This is especially true in the file finishing class, where the surfaces to be finished are of a wide variety of sizes, and as a result, there are problems in this field, such as labor-saving, automation, and inefficiency, which are lagging far behind. <<Means for Solving the Problems>> The present invention was made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a flexible file or string filter. Therefore, the present invention is constructed as follows. A string made of elastic material with a plurality of V-shaped grooves arranged in a star-shaped arrangement formed in the axial direction of the surface is used as a core, and a ring made of elastic material with a round cross-sectional shape, whose inner diameter is externally fitted to the string, is inserted into the inner surface of the through hole. A V-shaped groove is formed on the surface of the elastic string, and a round piece forming a cutting edge on the outer circumferential surface of the hollow material is sequentially assembled and communicated with each other. 《Operation》 Supports both ends of the string filter and performs cutting by reciprocating motion similar to normal sanding work, and also supports both ends with a bow-shaped support and gives elasticity to this support to accommodate curved surfaces. In addition, it is possible to connect both ends using an appropriate method to form an endless chain, and by running it in a winding manner, it can run in contact with a curved surface, a mixture of flat surfaces, and curved surfaces due to its flexibility. By using a wheel, it can be used for multiple purposes such as filing two-dimensional curved surfaces. <<Example>> A specific example of the string filter according to the present invention will be explained with reference to FIGS. 1 to 4. Figure 1 is a perspective view of a string filter, and the cross section of the elastic string (1) has a plurality of V-shaped grooves (2) formed in a star-shaped arrangement in the axial direction of the surface. A circle connected to the elastic material string (1) &! (3) and a ring made of elastic material (4) are shown. Round 31! A filter mesh (5) is formed on the outer peripheral surface of the filter (3), and the cutting edges of the filter mesh (5) are aligned in the axial direction on the inner surface of the through hole (6) of the round filter (3). The elastic material string (1
) The ■-shaped groove (6), which matches the surface shape of the filter, is related to the filter eye (5), and is round at each position during assembly! (3) enables communication. In addition, the filter mesh (5) of 9N (3) is the same as the well-known 9 filters that have been conventionally used for ironwork and other works. Figure 4 shows the case of bending the string filter, and the minimum bending radius R is the H dimension shown in Figure 2, which is a circle! 1 (3) is determined by selecting the spacing between the rings (4) made of elastic material and the width H' of the round filter (3). 《Effects of the Invention》 According to the present invention, it is not only possible to simply use it as a string, but also to run it endlessly so that it can be used for filtering or chamfering freely on any flat or curved surface, and its efficiency is high. It is several times more efficient than traditional sanding work, and by adding abrasive grains to the outer surface as a cutting edge instead of a filter, it is also possible to perform polishing work, and it can also be used as a pre-process tool such as the known profile sand can also be automated.
