The machine adopts a large span structure beam side beam to seal the oil penetration guide rail, and the automatic displacement is divided into pieces, The lifting system adopts the hydraulic descent (or the screw rod lifting transmission to realize the stable and rapid lifting of the knife, The transverse knife adopts the frequency converter to realize the stepless adjustment, automatic walking and cutting, and is specially equipped with the lifting and side beam transmission protection device. During processing, the waste materials can be directly placed on the ground to save the trolley and maintenance costs. The whole machine has fine processing, stable performance, high automatic production efficiency, convenient installation, operation and maintenance, and uses the international stone processing development needs.
