A stone cutting device configured to cut a workpiece with a plurality of cutting tools by swinging the cutting tools within a predetermined angle range. Each of the cutting tools includes: a blade extending in a length direction of the workpiece; and at least one cutting tip disposed on an end of the blade and protruding from the blade in a width direction of the blade so as to cut the workpiece while being reciprocated in a swinging motion. The stone cutting device includes a frame unit configured to combine and reciprocate the cutting tools and individually adjust tension in each of the cutting tools. The frame unit includes an actuator applying tension to the cutting tools so as to apply a load of 8 tons to 27 tons to each of the cutting tools.
