Do not file the oxide layer of the workpiece with a file. The hardness of the oxide layer is large and it is easy to damage the teeth. The oxide layer can be ground with a grinding wheel or with a chisel. 2. Use one side of the new file first and then use the other side after the side is blunt. 3. In the process of using the file always use a copper wire brush (or wire brush) to brush the debris embedded in the tooth groove along the direction of the tooth pattern. After use carefully brush all the debris before storing. 4. When using the file the speed should not be too fast otherwise it will be easy to blunt prematurely. The best frequency of the file going back and forth is 40 times/min and the length of the file is 2/3 of the total length of the tooth surface. 5. When using the file to file the workpiece the file should avoid water oil or other dirt which will corrode the file and slip during filing. 6. Diamond files are widely used for filing hard metals but not for filing soft metals such as aluminum copper etc. 7. Do not use the file as other tools such as: knocking prying pressing twisting pulling topping bumping and other operations. 8. When using the file the force should not be too large so as not to break or deform. 9. When storing files there should be no collision or overlapping storage; the humidity in the storage place should not be too high and it is required to keep dry and ventilated.
