How much is the pneumatic filer? What are the purchasing principles of pneumatic files?

Pneumatic file cutter is mainly used for cutting and other operations on the surface of the workpiece. It is forged from high-hardness alloy. The file teeth are generally durable and wear-resistant, and the shape is also uniform and uniform. As the saying goes, workers must first sharpen their tools if they want to do good, so the quality of the tool determines the effect of the later stage, but it is not enough to choose a reliable tool. We should also deeply understand all aspects of this tool Knowledge content. There are many brands and manufacturers of pneumatic filers on the market today, and different brands have different prices. Let's take a closer look at how much these brands of pneumatic filers cost.

  Pneumatic file selection principles

 

1. Selection of cross-sectional shape of file

The cross-sectional shape of the file should be selected according to the shape of the part being filed, so that the shape of the two fits. When filing an inner circular arc surface, choose a semicircular file or a round file (a workpiece with a small diameter); when filing an inner corner surface, choose a triangular file; when filing an inner right angle surface, you can choose a flat file or a square file. When using a flat file to file the inner right-angle surface, pay attention to make the narrow surface (light edge) of the file without teeth close to a surface of the inner right angle, so as not to damage the right-angle surface.

2. Selection of file tooth thickness

The thickness of the file teeth should be selected according to the remaining size of the processed workpiece, the processing accuracy, and the nature of the material. Coarse-tooth files are suitable for processing workpieces with large margins, low dimensional accuracy, large geometric tolerances, large surface roughness values, and soft materials; otherwise, fine-tooth files should be selected. When using, it should be selected according to the processing allowance, dimensional accuracy and surface roughness required by the workpiece.

3. Selection of file size specifications

The size of the file should be selected according to the size of the workpiece to be processed and the machining allowance. When the processing size is large and the margin is large, a file with a large size should be selected, and on the contrary, a file with a small size should be selected.

4. Selection of file tooth patterns

The tooth profile 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 tooth (milled tooth) file. The single tooth profile file has a large rake angle, a small wedge angle, and a large chip pocket. The chip is not easy to block and the cutting edge is sharp.

The above is the content about how much the pneumatic file machine is and the principle of purchasing pneumatic files. The pneumatic file machine is an indispensable tool in the processing industry, and it is also often a practical tool. Therefore, not only must it go correctly When purchasing a pneumatic filer, you must also master its correct use.
