The stone drilling machine is aimed at processing different sizes of stone. The stone center and the drill bit are not at the same point. There is no need to move the stone, just move the slide rail to quickly find the center point and directly process it. It is very convenient. In addition, the machine is equipped with a clamping device. The stone is very easy to fix during operation, and there will be no accidents or work injuries, which greatly increases the safety of workers.
