The improvements to saw machines and sawing methods to cut stones consist in modifying of the hoops (4), the tensioners (2), the frames (3), the tensioning systems and other parts of the machines, in order to take better advantage of the machines and to increase the feed. The collective hydraulic tensioning is set. A better use is made of the hoops (4) and of the shot. The down-times for substituting and changing the hoops (4) are reduced. The beginning and the end of the saw-cutting are made easier. A reduced flow of sludge per groove is used. The sludge consists of calcic ferrite. The machine has to operate in conditions where the sludge adheres to the extremities of the hoops (4) which project from the block. The amount of the cuttings is limited in the sludge. An economical, silent and high-production machine is provided. |
