Key Points for Grinding Alloy Saw Blades

Alloy saw blades are a type of cutting tool, mainly used for sawing wood, aluminum alloy, iron, steel and other materials. It is mainly composed of a saw blade and an alloy cutter head, with various tooth shapes and relatively complex grinding. Many users report that the alloy saw blade is not sharp after polishing and is not easy to use. How should alloy saw blades be sharpened?

The blade sharpening is not reasonable. The grinding direction of the alloy saw blade edge is very critical. The original grinding angle must be installed and must not be modified. This directly affects the sharpness of the saw blade after grinding.

However, many companies use simple grinders to grind saw blades, perhaps to do some leveling and simple grinding of the saw blades. Precision grinding is difficult for blades. Users report that the alloy saw blade is not sharp after grinding, which is mostly caused by this reason.

First, use a detector to check the damage and extent of the alloy saw blade. The saw blades of alloy saw blades are prone to cracks or breaks, or have scars, missing corners, etc. During the sawing process, the saw board is easily deformed due to high temperatures. As long as the damage is not serious, it can usually be repaired. After the inspection, the alloy saw blade will be cleaned. Sticky substances will appear on the surface of the alloy saw blade after being used under various complex conditions. The cutting tools will be cleaned with special equipment, and only after cleaning can precise grinding work be carried out.

Generally, the tooth back of the alloy saw blade is ground first. The tooth back must be ground to ensure the discharge of chips. If the grinding time is too short, smooth chip removal from the alloy saw blade cannot be guaranteed. Generally skilled workers can master the grinding time. Then do a good job of replacing the teeth, especially if there are obvious scars or chipped corners, it is more necessary to replace the teeth one by one. And grind it again to ensure that the height difference reaches the standard.
