How To Maintain Wood Chipper Blades?

Maintaining Wood Chipper Blades is crucial for ensuring their performance and service life.

Firstly, regular cleaning is essential. After using the wood chip machine, impurities such as wood fibers, resin, and dust may remain on the blades. If these impurities are not cleaned up in time, they will affect the cutting performance of the blade. Specialized tools such as brushes or high-pressure air spray guns can be used to remove impurities from the surface of the blade. For those stubborn resins that stick to the blade, appropriate solvents can be used for cleaning. However, when using solvents, it is important to ensure that they do not corrode the blade material.

Secondly, pay attention to sharpening the blade. As the usage frequency increases, the blade edge will gradually wear out and become less sharp. When it is found that the cutting efficiency has decreased, such as when cutting the same piece of wood requires more power, or when the cutting surface of the wood becomes rough and uneven, it may be necessary to sharpen the knife. It is best to use professional sharpening equipment for sharpening, and strictly follow the design angle of the blade for grinding. For example, if the original cutting edge angle of the blade is 25 °, then it is also important to maintain this angle as much as possible when sharpening. The frequency of sharpening depends on the hardness of the wood and the strength used. Generally speaking, when cutting harder wood or after prolonged use, the frequency of sharpening will be higher.

Furthermore, it is also important to check the wear of the blades. Regularly conduct a comprehensive inspection of the blade to see if there are any areas of chipping, cracks, or excessive wear. If small chipping is found on the blade, it can be repaired by proper polishing. But if the blade has cracks or severe wear, it should be considered to replace the blade.

In addition, when storing the blades of the wood chip machine, they should be placed in a dry and ventilated environment to avoid rusting of the blades. If the blade is not used for a long time, a layer of rust proof oil can be applied to the surface of the blade, which can effectively prevent the blade from rusting due to moisture. When reusing, it is necessary to wipe the rust proof oil clean to ensure cutting quality.
