Abstract
A wire saw which can improve a working accuracy is provided. When a wire goes to a rightward direction by a rotation of a moving motor, the wire is inclined in such a manner as to be moved toward a right and outer periphery from an inner portion of a work, and a cutting start point of the work becomes a point within the work. Further, when a wire goes to a leftward direction by a rotation of the moving motor, the wire is inclined in such a manner as to be moved toward a left and outer periphery from an inner portion of a work, and a cutting start point of the work becomes a point within the work. Then, the work is cut from the cutting start point by a sufficient slurry containing float abrasive grains supplied to a portion on the wire.
