Alloy saw blade is a kind of cutting tool, which is mainly used to cut wood, aluminum alloy, iron, steel and other materials. It is mainly composed of a saw blade and an alloy cutter head, and has various tooth shapes, so it is relatively complicated to grind. Many users reported that the alloy saw blade is not sharp after grinding, and it is not easy to use. How should the alloy saw blade be sharpened?
The sharpening of the blade is unreasonable. The grinding direction of the alloy saw blade edge is very critical, and the original angle grinding must be installed and must not be modified. This directly affects the sharpness of the saw blade after grinding.
However, many companies use a simple grinding machine to grind saw blades, which may be to do some leveling and simple grinding of the saw blade. As for the blade, it is difficult to achieve precision grinding. Users report that the alloy saw blade is not sharp after grinding, which is mostly caused by this reason.
First of all, use the detector to check the damage and degree of the alloy saw blade. The blade of the alloy saw blade is prone to cracking or breaking, or scars and missing corners. The sawing board is easily deformed by the high temperature during the sawing process. As long as the damage is not very serious, it can generally be repaired. After the inspection, the alloy saw blade will be cleaned, and the surface of the alloy saw blade will have sticky substances after being used in various complex conditions. Fengjinrui knives will be cleaned with special equipment, and accurate grinding work can only be carried out after cleaning.
Generally, the tooth back of the alloy saw blade is ground first, and the tooth back must be ground to ensure the discharge of chips. If the grinding time is too short, it cannot ensure smooth chip removal of the alloy saw blade. Generally, skilled workers can master the grinding time. Then do the tooth replacement work, especially if there are obvious scars or missing corners, it is necessary to replace the teeth one by one. And regrind to ensure that the height difference reaches the standard.
