It is possible and this also falls within the scope of the present invention.

According to the curved surface processing apparatus for stone according to the present invention made as described above, because the cutter is made to swing at a predetermined angle while rotating, the curved surface is naturally formed (grinding) is made as the workpiece comes into contact with the cutting tip.

Therefore, when a curved surface is formed on a predetermined portion of stone or the like, which is widely used as a material for a building or a facility, the curved surface can be formed more easily and quickly than the manual work, thereby greatly saving manpower and processing time and reducing cost.

Particularly, when one edge is curved to approximately quadrant (90 °), such as a road boundary stone, a large amount of processing can be performed on a curved surface having a natural and uniform shape.

Furthermore, since it is possible to adjust the swing radius according to the size of the curved surface (curvature radius), it is possible to form curved surfaces of various sizes.

According to the curved surface processing apparatus for stone according to the present invention made as described above, because the outer diameter of the shank forming the cutter gradually increases in the direction of the workpiece, the curved surface is naturally formed while the depth of cut increases.

Therefore, the overload does not occur or the components for the cutter rotation motor or the motor for swinging the cutter is not overwhelmed, so the life is extended and the vibration is reduced during cutting, thereby improving the cutting property.

According to the curved surface processing apparatus for stone according to the present invention made as described above, it is possible to adjust the vertical gap between the workpiece and the cutter through the height adjustment device, it is possible to form a curved surface on the workpiece of various sizes.
