Between the front end in the linear reciprocating direction and the front end of the stone placed on the stone placing section, and the rear end in the linear reciprocating direction of each blade and the rear end of the stone placed on the stone placing section. And the abrasive liquid is allowed to flow down onto each blade from the abrasive liquid jet port, so that a certain amount of abrasive can be attached to the blade of the cutting blade, By reducing the possibility of abrasive particles entering,
There is an effect that only a predetermined amount of abrasive grains attached to the blade enter, and a cutting stone having a predetermined thickness can be obtained with the abrasive grains. Further, according to the stone material cutting device of the present invention, the abrasive liquid is caused to flow down to the most effective portion by the abrasive liquid supply unit. This has the effect that cutting can be performed. Therefore, according to the present invention, the abrasive liquid is reduced from directly entering the cuts of the stone material, and the abrasive liquid is not excessively attached to each blade, and the stone material is reduced with a small amount of the abrasive liquid. This has the effect of providing a stone material cutting device capable of cutting to a preset thickness.
