What is the filing of professional saw chains?
The left and right cutting teeth on the professional saw chain are cutting tools, and the cutting edge becomes blunt after a period of use. In order to cut smoothly and keep the cutting edge sharp, it is necessary to repair the file.
Precautions for file repair of professional saw chains:
1. Choose a round file suitable for repairing professional saw chains.
The cutting teeth, size, and arc of various types of professional saw chains are different. Each type of chain requires a certain round file standard. There is a detailed introduction in the manual, be sure to check it carefully.
2. Pay attention to the direction and angle of the saw chain when repairing the file.
The file should be repaired forward in the direction of the cutting edge. Generally, the included angle of the cutting edge of a professional saw chain is about 30 degrees, while the front is high and the back is low, and the included angle is about 10 degrees. These angles vary according to the hardness of the material being sawed and the usage habits of the saw. At the same time, attention should be paid to the symmetry of the left and right cutting teeth. If the deviation is too large, the saw will run off and the saw will be oblique.
3. Pay attention to the height of the limit tooth of the saw chain.
A part of the front of each cutting tooth protrudes, this is the limit tooth, which is 0.6---0.8 mm lower than the upper edge of the cutting edge, and the cutting amount per tooth is so thick. When filing the cutting edge, pay attention to its height. . If there are more cutting edge repair files, the relative cutting edge of the limit tooth will become higher, and the cutting amount will become smaller each time, which affects the cutting speed. If the cutting edge is lower than the limit tooth, it will not eat wood and cannot cut. The limit tooth repair file is too low, and each cut is too thick, which is likely to cause the "knife" and the saw will not move.
