Here is a brief introduction to the function of a file and how to extend its service life:

              (1) The function of a file:

The cross-section of the rod used for grinding is a polygon, with curved and straight edges on several sides of the polygon. The two adjacent straight edges form a depression, while a groove is formed on the file base. A sharp angle can be sandwiched between the two adjacent straight edges. This multi-purpose file can be used for nail trimming, fish hook grinding, key repair, glass hole grinding, car ignition platinum grinding, etc. It has become a necessary item in daily life, a portable tool for electricians and fitters, and even can be used for carving handicrafts, and so on Made of high-quality carbon steel T12, it is durable and has sharp cutting teeth! 3PC Woodworking File Hanging Bag Packaging, Made of High Quality Carbon Steel T10, Durable, Sharp Teeth! 6PC assorted file, made of carbon steel after heat treatment and finely chopped, durable!!

              (2) Teach you how to extend the lifespan of the file:

As is well known, filing is an important basic operation of fitters. And there are many types of files, including round files, flat files, shaping files, flat files, triangular files, etc. Different products use different specifications of files, and the correct processing tools are selected when processing the products, which also plays a key role in extending the service life of the files. The machining method of using a file to cut and process a workpiece to meet the required dimensions, shape, position, and surface roughness is called filing. It can process the inner and outer planes, inner and outer surfaces, inner and outer corners, grooves, and various complex shaped surfaces of workpieces. Under the conditions of modern industrial production, there are still certain parts that require manual filing to be completed, such as the trimming and repair of individual parts during the assembly process, the processing of complex shaped parts under small-scale production conditions, and the processing of templates and molds. From this, it can be seen that how to maintain the file to extend its service life is also a very important step. Below, I will share with you some of the experiences I have gained in the teaching guidance process and work.
 
Firstly, before use, carefully inspect the file for damage and ensure that the teeth are intact; Is there any hard skin on the surface of the castings that need to be processed? If there is any hard skin, it should be first ground off with a grinding wheel or filed off with an old file and the toothed side of the file, and then normal filing processing can be carried out.
 
Secondly, the following items should be noted during use:
 
1、 When using a new file, one side should be used first, and the other side can only be used after being blunt. Do not use both sides of the file alternately during the filing process.
 
2、 When rough filing workpieces, it is necessary to fully use the effective full length of the file to improve filing efficiency and avoid local wear of the file teeth. When using a fine board file to finely file the workpiece, in order to achieve a smoother machining surface, chalk dust can be evenly applied to the tooth surface of the file, reducing the cutting amount of each file and making it difficult for the file chips to embed into the tooth pattern of the file. The surface roughness of the processed surface can reach Ra1.6 micrometers.
 
3、 During use, it is necessary to clean the file debris embedded in the teeth with a steel wire brush in a timely manner. When cleaning, it should be carried out along the lines of the file teeth to prevent incomplete cleaning. Never blow the file with your mouth, nor touch the surface of the file with your hands, nor rinse it with water.

4、 During use, the file should not be used as a pry bar or hammer, nor should it be contaminated with lubricating oil or water.
 
Finally, after use, the file must be cleaned to avoid rusting. When putting it into the toolbox, it should not be stacked together with other tools or workpieces, nor should it overlap with other files to avoid damaging the file teeth.
 
Of course, the strength of both hands and the speed of filing are also important for the lifespan of the file. Only by following the correct operating procedures and cherishing the file can the service life of the file be extended.
