SQC/PC-2200/2500/2800-4D uses PLC system and Human-machine interface, combined with Ultra-high precision rotary encoder to slice, uses inverter to control left-right feeding and adjusts the speed according to the stone material. It uses hydraulic lifting system, and the forward-backward slicing uses high-precision screw nut driving, automatic slicing. The key part adopt imported good-quality spare parts. The block can be placed on the ground directly and economize the worktable and its maintenance costs; The whole machine is featured with high cutting efficiency, high slicing precision, flatness of plate after cutting, high stability, easy-operating to suit granite and marble block with high value.
