This machine boasts its ability to work at the highest efficiency while with the lowest energy consumption. Suspension structure is adopted in the tgq-160 stone cutting machine. The main working part can move up-and-down with the help of lead-screw. The cutting of blocks is realized with the blades move down slowly and the trolley moves right and left regularly, both of which are powered by electric motor. And the novel design of upper trolley well solves the problem of slicing. The spindle, as a crucial part, also has been specially processed to improve its stiffness. The feeding and retrieving of blades and the movement of trolley are centrally controlled by the control panel with high level of automation and the slabs that they produce are plane on the surface.
