File tools provide convenience for decoration

From a literal explanation, it can be seen that this tool is specifically designed for surface finishing, and its size varies, so the price of surface finishing tools also varies.When it comes to surface finishing tools, the first thing you can think of is a file, which is made of carbon tool steel T12 or T13 after heat treatment, and then quenched into the working part. There are many fine teeth on the surface of the file, used to smooth the rough parts on the workpiece. It is a manual tool. The file, as a tool, has been used by ancestors for a long time in ancient times. With the development of technology and the improvement of technology, its material has also undergone changes. It is made of carbon steel through processes such as rolling, forging, annealing, grinding, tooth cutting, and quenching, making it more durable and effective.

As a hand tool and a surface dressing tool, the seemingly simple structure of a file actually consists of 13 parts. It is composed of a file body, a file handle, a parallel part of the file body, a tip, a main file pattern, auxiliary file patterns, edge file patterns, an oblique angle of the main file pattern, the number of file patterns, the bottom line of the file teeth, tooth height, and the front angle of the teeth. Its types can be further divided into fitter files, irregular files, and shaping files, and can be further divided into flat files, semi circular files, triangular files, double semi circular files, and so on. And its specifications are also diverse, but this type of surface finishing tool is relatively cheap.

Although a file is a very simple surface dressing tool to use, it is important to pay attention when selecting it. Firstly, the cross-sectional shape of the file should be selected based on the assembly of the parts being filed, so that the shapes of the two can adapt to each other. If filing the inner curved surface, choose a semi circular file or a circular file; When filing the inner corner surface, be sure to choose a triangular file; When filing the inner right angle surface, flat files or square files can be used. Secondly, the thickness of the file teeth should be selected appropriately, and the thickness of the file teeth should also be selected based on the size of the machining allowance, machining accuracy, and material properties of the workpiece. For coarse tooth files, they are suitable for machining workpieces with large margins, low precision requirements, large positional tolerances, high surface roughness, and soft materials; For fine-tooth files, it is necessary to choose workpieces with small machining allowance, high precision scale, small positional tolerance, low surface roughness, and hard materials. Finally, when selecting the size specifications of the file, when processing large sizes and large margins, it is necessary to choose a file with a larger size specification. On the contrary, a file with a smaller size specification should be used. Also, pay attention to the file teeth.
