The advantage of saw blade is that its quality is higher than that of domestic saw blade, the quality of sawing workpiece is high, the surface is relatively smooth after cutting, there is no burr in sawing, the integration of equipment is relatively strong, and the sawing is more stable. The cost of single sawing is obviously lower than that of domestic saw blade. The disadvantage of saw blade is that the purchase price is higher than that of domestic saw blade. The brand selection of saw blade is very important. At present, there are many shoddy or OEM products in China's market. The advantage of domestic saw blade is that we don't have to worry too much about buying a brand as a counterfeit product. Compared with the comprehensive service, the comprehensive service is more convenient and fast, and the actual purchase is more convenient. The disadvantage of the saw blade is that the actual service time is not as good as that of the imported saw blade. The sawing quality of the saw blade is obviously low. There is burr on the cutting edge of the workpiece, which usually requires additional labor cost. The integration of the saw blade equipment is not as good as that of the imported saw blade, which is easy to cause sawing instability When the quality requirement of the workpiece to be sawed is not high enough and the quantity is small, it is generally recommended to use domestic saw blade. If the quantity is large, the actual requirement is relatively high, or the quality control is strict, it is recommended to use the imported saw blade.
