Transportable diamond wire saws are provided to work in differ rent configurations depending on the

cutting operation where the cutting plane is orthogonal to the rail support surface and the coated

diamond wire has no path variation; coated diamond wire rotation can be clockwise or counter

clockwise; according to the position of the transportable diamond wire saw inside the quarry or

workstation and the path of the coated diamond wire, different types of vertical cutting are defined:
