Pay attention to the details of grinding woodworking finger joint knives

1. To grind finger-joint knives, you should use a professional grinding wheel (500#) for grinding finger-joint knives. It is not recommended to use a grinding wheel for grinding saw blades.
2. Check the size of the sorting knife before grinding (160).
3. Grind once every 2 days, grind 8-10 filaments each time, and can be grinded 55-60 times (that is, the life span can reach 3 to 4 months).
4. When grinding, the blade must move left and right (front and back) in a balanced manner, and cannot press the grinding wheel surface for grinding. This will cause waves and cause the alloy to crack and break.
5. If it is worn out, it must be scrapped and cannot be used again (for example: the alloy is unbalanced with one side larger and the other smaller, deformation, fracture, and tooth chipping).
