Tips: Files selection guide
1. The selection of file section shape
The cross-sectional shape of the file should be selected according to the shape of the part to be worked with, so that the two shapes are compatible. When filing the inner arc surface, you are recommended to select a half round file or a round file (small diameter workpiece); when polishing the inner corner surface, a triangular file is the option; when filing the inner right-angle surface, a flat file or a square file can be chosen. When using a flat file to sharpen an inner right-angled surface, you are suggested to use the narrow surface (smooth edge) of the file without teeth close to the inner right-angled surface to avoid scratching the right-angled surface.
2.The choice of file tooth roughness or smoothness
The roughness or smoothness of the teeth of the file should be selected according to the size of the workpiece filing allowance, filing accuracy, and material properties. Coarse-tooth files are suitable for sharpening work pieces with large allowance, low dimensional accuracy, large geometric tolerances, large surface roughness values, and soft materials; otherwise, fine-tooth files should be selected.
3. The selection of file size specifications
File sizes should be chosen according to the size of the workpiece to be processed and the filing allowance. When the processing size is large and the margin is large, the file of large size should be used, and the file of small size should be used on the contrary.
4.The selection of file tooth pattern
The tooth pattern of the file should be selected according to the nature of the material being filed. When filing soft materials such as aluminum, copper, mild steel, etc., it is best to use a single-cut file. The single-cut file has large rake angle, small wedge angle, large chip pocket, chip is not easy to block, and the cutting edge is sharp.
