Multi-blade saw machines are increasingly favored by wood processing factories because of their simple operation, high processing efficiency, and wood production standards. However, multi-blade saws often have burning deformation in daily use, especially in some newly opened processing plants Problems occur more frequently. Burning blades not only increases the cost of saw blades, but also frequently replaces saw blades and directly leads to a decrease in production efficiency. Why does the burning problem occur and how to solve it?

1. The heat dissipation and chip removal of the saw blade itself is not good:

The burning of the saw blade occurs instantly. When the saw blade is sawing at high speed, the strength of the saw blade will continue to decrease as the temperature continues to increase. At this time, if the chip removal is not smooth or the heat dissipation is not good, it will easily generate a lot of friction heat 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, choose equipment with cooling device (water cooling or air cooling) to reduce the sawing temperature of the saw blade, and check regularly to ensure that the cooling device runs smoothly; b, choose a saw blade with cooling holes or a scraper to ensure that the saw blade The blade itself has good heat dissipation and chip removal, which reduces the friction between the saw board and the cutting material to reduce frictional heat;

2. The saw blade is thin or the saw board is poorly treated:

Because the wood is harder or thicker and the saw blade is too thin, it exceeds the bear limit of the saw blade. When sawing, the saw blade is rapidly deformed due to excessive resistance;The saw blade is not strong enough due to improper processing. It can't bear the cutting resistance that it should bear and is deformed by force.

Solution: a. When purchasing saw blades, you should provide the supplier with clear processing conditions (cutting material, cutting thickness, plate thickness, equipment structure, saw blade speed and feeding speed); b, understand the supplier's production and quality control system; c, purchase saw blades from professional manufacturers;

The above are the several  reasons for multi-blade saw burnt summarized by HunanDonglai Metal Technology Co., Ltd. However, due to the extremely complicated situation faced by each processing factory in actual production, the reasons for saw blade burnt in many cases need to be based on the actual production process To judge, analyze and solve. We are willing to communicate and discuss with colleagues in multi-blade saw equipment and wood processing factories to improve our saw blade manufacturing level and reduce saw blade loss when customers saw.
