After cutting a lot of left and right side until the cutting must be re-processed, and if the shaking is severely caught the wrong cutting position as shown in FIG.

Therefore, the vibration of the diamond cutting saw 20 should be prevented as much as possible. For this purpose, the diamond tip 21 is thickening the thickness of the diamond cutting saw 20 fixed to the outside.

However, if the thickness of the diamond cutting saw 20 is thickened, the rotational movement can be prevented to some extent, but the cutting width is increased when cutting the stone (S), so that a lot of stone powder is generated, and the loss of the stone is many, and the diamond cutting saw 20 is thick. While the price is rising, the driving load is large, and the power loss is also a big problem.

The present invention is to prevent the shaking of the diamond cutting saw for stone cutting machine by installing an ultra-hard dustproof pad between the diamond cutting saw to eliminate the vibration of the diamond cutting saw.

The present invention is a stone cutting saw having a plurality of diamond cutting saws rotatably installed inside the open side of the saw blade, by installing an ultra-hard dustproof pad between each diamond cutting saw to prevent vibration during the rotation of the diamond cutting saw This is done by preventing it with a pad.

According to the present invention, after the dust pad is inserted into the insertion groove of the pad fixture, the fixing bolt is fixed to one side of the pad fixture and the dust pad is protruded so as to be located between the diamond cutting saws.

In addition, the present invention is formed with a supply pipe for supplying water to the pad fixture and the dustproof pad.

And the pad fixture is fixed to the dust pad is possible to move the position inside the diamond cutting saw by a separate drive device.
