Bridge type stone cutting machines operate by moving a cutting tool, usually a diamond saw blade, along the X, Y, and sometimes Z axes. The machine's bridge structure provides stability and support for the cutting tool, allowing it to cut through the stone with precision. The blade rotates at high speed, driven by a powerful motor, and the movement of the bridge and cutting tool is controlled by CNC systems, manual controls, or a combination of both, depending on the machine's design, to achieve the desired cuts.
