10 ways to choose and use steel files to meet specific processing needs
To correctly select and use a steel file to meet specific processing needs, consider the following aspects:
Workpiece Material
Choose a steel file with the appropriate hardness based on the hardness and properties of the material being processed. For example, when working with hard steel, a file with a higher hardness should be selected.
Processing Requirements
Select the right file based on the required processing precision and surface roughness. A coarse file should be used for rough machining, while a fine file is suitable for precision work.
Workpiece Shape
The shape of the file should be compatible with the shape of the workpiece. For instance, a set of shaper files (assortment files) is suitable for trimming small parts of a workpiece, while a flat file is ideal for filing flat surfaces, outer circular surfaces, and convex arc sur
File Size
The length and cross-sectional size of the file should be chosen based on the size of the workpiece's processing surface and the amount of processing allowance.
Type of File Markings
File markings are divided into single and double patterns; single pattern files are suitable for soft materials, while double pattern files are for hard materials.
File Hardness Levels
The hardness levels of steel files are typically measured by the Rockwell Hardness scale, and different hardness levels are suitable for different processing needs.
Maintenance of Files
Proper maintenance of files after use is necessary to extend their service life.
National Standards
When selecting and using steel files, refer to the national standard GB/T 5806-2003 "General Technical Conditions for Steel Files" to ensure the quality and technical requirements of the files.
Holding Method of the File
The correct holding method can improve work efficiency and reduce fatigue.
Filing Techniques
Understand and master appropriate filing techniques, such as controlling the force during filing and the direction of filing.
By considering these factors comprehensively, you can correctly select and use a steel file to achieve the best processing results.
