How to determine whether the blade needs sharpening

Cutting saw is a main  equipment in the plywood veneer production line.Today let us talk about the saw blade. 

After the saw blade has been sawed for a certain number of plates, it needs to be replaced for grinding, so that it can be used next time. From what aspect should the blade be judged when it needs to be repaired?

1, there are burrs on the edge of the board

Under normal circumstances, the sawing half burrs will be less or easy to remove. If you find that there are too many burrs or chipping, and it is difficult to remove, you should consider whether the saw blade needs to be replaced.

2, the sound is abnormal

Under normal circumstances, the sound of the saw blade is relatively uniform, no noise, but suddenly one day when the sawing sound is too loud, or abnormal, should be checked immediately, if there is no equipment, etc., can be used as a replacement saw blade The basis for grinding.

3, the smoke is too large

When the saw blade is cut, it will produce a certain amount of smoke due to friction. Under normal circumstances, it will be light. If it is found to have a pungent smell or too much smoke, it is likely that the sawtooth is not sharp and needs to be replaced. mill.

4, the edge of the board

During the processing of the sheet metal, you can judge the condition of the carbide saw blade from the side section of the sawing board. If the cross-section surface is too much or the sawing tolerance is too large, the saw blade can be inspected. The problem can be used as a basis for replacing the grinding.

Reasonable maintenance of the carbide saw blade is more conducive to the cost control of the enterprise and the quality of the equipment.
