The closed frame gang saw can cut marble slabs of various thickness. The closed frame gang saw is realized to install from 80 up to 100 diamond blades. The closed structure means that the blade holder frame is not moving up and down, the vertical movement of the block is given by n.4 worm screws connected to the block trolley.
The rectilinear movement is given on 4 articulated rectilinear guides attached to the closed frame structure. These rectilinear articulated guides vastly reduce maintenance costs because they do not require replacement like the traditional slide ways which are subject to a continuous wearing. The best solution for higher speed , more accuracy and precision is one where the connecting rods move together with the blades horizontally along a single axis only. This means there is no dispersion of mechanical thrust in other directions. The block is stable when fixed on the upward moving platform. The platform runs on 2 plane and 2 prismatic vertical slide ways. These plane and prismatic slide ways prevent any deviation or tilting away from the vertical axis. The trolleys are entering laterally and frontally. The 80 and 100 models have a linear stroke of the blade of 800 mm or 1000, the longer stroke guarantee a bigger production.
