Stone material saw

The invention aims at providing a stone material saw capable of cutting a plurality of sheet materials at the same time and ensuring that the cut sheet materials are the same in thickness. The stone material saw can improve cutting efficiency and quality. The stone material saw comprises a rotating shaft, a power device driving the rotating shaft to rotate and saw blades fixed on the rotating shaft and is characterized in that the number of the saw blades is at least three, and distances of adjacent saw blades are the same. In the stone material cutting process, the saw blades can be used for cutting stone materials at the same time, so that working efficiency is improved. Due to the fact that the distances between the adjacent saw blades are the same, the same thickness of cut stone sheet materials is ensured.
