Granite is a kind of hard crystalline stone formed by igneous rock, and also a building material with super hardness and wear resistance. It is precisely because of this characteristic of granite that it is difficult to process it. Even if you use a professional granite saw blade to cut, you will encounter these problems

 

First of all, burn the blade when cutting. The reason is that the matrix hardness of the granite saw blade is too hard, the diamond of the cutter head falls off, and it may also be that the cutting edge of the saw blade is insufficient in the early stage, resulting in insufficient diamond cutting height

 

Second, the sawblade will fall off during cutting, because the sintering body of granite saw blade is arranged loosely and the material is segregated, which will lead to the sawblade falling off during processing

 

Third, the cutter skips when cutting. The diamond particles of granite saw blade tip are unevenly distributed, too concentrated or too rare, which will cause the diamond to fall and then cause the cutter skips

 

Fourth, spark during cutting. This phenomenon is also caused by falling diamond particles and improper dispersion. At the same time, too hard or too soft matrix may also have an impact

 

Fifth, attenuation during cutting. First, during the heating and sintering process of granite saw blade, the temperature gradient, powder activity status, and low melting point material dispersion difference between the tip and the bottom of the blade lead to the change of sintering arrangement and mechanical properties; Secondly, in the process of processing, because of the high hardness of granite, the arranged strength of the matrix is weakened by the vibration and impact force that the granite saw blade touches and conducts, resulting in the reduction of the matrix's holding force on diamond particles; Then, during the cutting process, the heat will be continuously accumulated, which will weaken the mechanical properties of the granite saw blade sintering body
