STONE CUTTING APPARATUS

Stone cutting device according to the present invention， a cutting device provided to cut a workpiece by swinging a plurality of cutting tools at a predetermined angle， the cutting tool having a blade extending in the longitudinal direction of the workpiece and a width at the end of the blade It is provided to protrude in the direction， and includes at least one cutting tip that reciprocates by a swing motion and cuts a workpiece， and is provided to combine the plurality of cutting tools to reciprocate and to individually adjust the tension to each cutting tool. The frame portion; includes， the frame portion， the pipe of the cylinder that transmits the hydraulic pressure from the inside， to give the cutting tool a tension of up to 27 tons of load， a tension of up to 11 tons of load is applied Actuator with higher hydraulic transmission area or higher strength than the pipe of the actuator cylinder that can withstand It should.
