Multi-blade saw machinery is increasingly favored by wood processing plants because of its simple operation, high processing efficiency and standard output. However, multi-blade saws often suffer from burnt and deformed sheets during daily use, especially in some newly opened processing plants. Problems occur more frequently. Burnt blades not only increase the cost of saw blade use, but frequent replacement of saw blades directly leads to a decrease in production efficiency. Why does the burning problem occur and how to solve it?
1. The saw blade itself has poor heat dissipation and chip removal:
The burning of the saw blade occurs in an instant. When the saw blade is cutting at high speed, the strength of the saw board will continue to decrease as the temperature continues to increase. At this time, if the chip removal or heat dissipation is not smooth, a large amount of friction heat will easily be generated. Vicious cycle: When the temperature is higher than the heat-resistant temperature of the saw board itself, the saw blade will be burned instantly.
Solution:
a. Purchase equipment with a cooling device (water cooling or air cooling) to reduce the cutting temperature of the saw blade, and check regularly to ensure that the cooling device operates smoothly;
b. Purchase a saw blade with heat dissipation holes or a scraper to ensure that the saw blade The blade itself has good heat dissipation and chip removal, reducing the friction between the saw plate and the cutting material to reduce frictional heat;
2. The saw blade is thin or the saw board is poorly processed:
Because the wood is hard or thick and the saw blade is too thin, it exceeds the endurance limit of the saw board. The saw blade is quickly deformed due to excessive resistance during sawing; the saw board is not strong enough due to improper handling. It cannot withstand the cutting resistance it should bear and is deformed by force.
Solution:
a. When purchasing a saw blade, you should provide the supplier with clear processing conditions (cutting material, cutting thickness, plate thickness, equipment structure, saw blade speed and feed speed);
b. Understand the supplier's production and quality control system;
c. Purchase saw blades from professional manufacturers;
