APPARATUS FOR CUTTING CURVED SURFACE OF STONE

摘要

An objective of the present invention is to provide an apparatus to cut a curved surface of a stone which prevents a wearing off of one side. According to the present invention, the apparatus to cut the curved surface of the stone comprises: a moving unit (100) on which the stone moves along a guide rail (110) installed in a floor; a support unit (200) including a vertical frame (210) vertically installed in both sides of the guide rail (110); and a cutting unit (300) to move vertically along the vertical frame (210) of the support unit (200), and cut a curved surface on the stone (B) moved by the moving unit (100). The cutting unit (300) comprises: a driving wheel (310) installed in the vertical frame (210) on one side to be moved vertically; a driven wheel (320) installed in the vertical frame (210) on an other side to be moved vertically with the driving wheel (310); a cutting wire (301) wound on the driving wheel (310) and the driven wheel (320) to cut the stone (B); a driving wheel drive means (330) to supply power to the driving wheel (310); a lifting means (340) to vertically move the driving wheel (310) and the driven wheel (320) together; and a cutting wire rotating means (400) installed in the vertical frame on one side and the other side to vertically be moved, installed in a circulation path of the cutting wire (301) between the driving wheel (310) and the driven wheel (320), and shaft-rotates the cutting wire (301) to change a surface coming in contact with the stone (B) when cutting the stone (B).
