How to select the grinding speed of rotary file?

Hard alloy rotary files should run at a speed of 1 to 3 feet per minute. According to this standard, there are many kinds of rotary files for grinding mill selection. For example, a file with a diameter of 3/16 to 3/8 can be selected for a grinder with 30, – revolutions; 22, – The grinder with the number of revolutions can choose the file with the diameter of 1/4 to 1/2. However, in order to operate more effectively, it is best to choose the most commonly used diameter. In addition, the maintenance of grinding environment and system is also very important. Suppose that a grinder with 22, – revolutions often fails, which may be due to too few revolutions. Therefore, we recommend that you often check the air pressure system and sealing device of the grinder.

Reasonable running speed is really very important to achieve the required cutting degree and workpiece quality. Increasing the speed can improve the processing quality and prolong the tool life, but may cause the file handle to break; Lowering the speed will help to cut off the material quickly, but it may cause the system overheating and the fluctuation of cutting quality. For each type of rotary file, the appropriate operating speed shall be selected according to the specific operation.

How about Sanlin hot selling carbide burrs?

How about Sanlin rotary file? Sanlin rotary file is used to process all kinds of metal machinery and remove flash and burr, so the better the material, the more it can play a great role in work. Taking SATA SATA hard alloy rotary file series as an example, the material is hard alloy, with high hardness, good toughness, wear resistance, heat resistance and corrosion resistance.

Teach you the principle of selection. Selection of section shape of cemented carbide rotary file

The section shape of cemented carbide rotary file tool shall be selected according to the shape of the part to be filed, so that the shape of the two can be adapted. When filing the inner arc surface, choose a semicircle file or a round file (small diameter workpiece); When filing the internal corner surface, choose a triangular file; When filing the inner right angle surface, flat file or square file can be selected. When using a flat file to file the inner right-angle surface, pay attention to make the narrow side (smooth side) of the file without teeth close to one side of the inner right-angle surface to avoid damaging the right-angle surface. Selection of file tooth thickness.
