2. Description of the Related Art A hole saw, for example, is known as a device for cutting a circular road surface. This hole saw consists of a cup-shaped core bit whose center is connected to the rotating shaft.
This core bit has a shape in which a diamond tip or the like is embedded with the opening edge of the core bit as the cutting edge surface, and circularly cutting is performed by pressing the core bit against the surface to be cut while rotating the rotary shaft. By the way, in such a conventional apparatus, since the diameter and depth of the core bit are limited, the diameter of the object to be cut and the cutting thickness are limited.

On the other hand, a cutting device using a wire saw has been studied. This product has a rotary shaft that penetrates the center hole of the object to be cut through the center hole, has swing arms attached to both ends of the rotary shaft, and has guide pulleys attached to the swing ends of both arms. A wire saw is hung through a through hole that penetrates the target object, and a wire saw driving motor connected to a pulley is driven while rotating the rotating shaft by a turning motor, and cutting is performed while moving along a trajectory like a compass. Since a circular hole having a size corresponding to the length of the arm can be formed, its diameter and cutting thickness can be freely set.
