Abstract
The present invention is a wire saw in which a wire for slicing is wound around a plurality of rollers to form a wire row; the wire for slicing is driven axially in a reciprocating direction; a workpiece is sliced simultaneously at a plurality of points arranged in an axial direction by feeding the workpiece against the wire row with the workpiece cut into while a slurry is supplied to the wire for slicing; the wire saw controlling in such a manner that the workpiece is extracted while the wire is caused to travel at a speed of 2 m/min or less at the time of extracting the workpiece from the wire row after slicing the workpiece. As a result, there is provided a wire saw in which the workpiece sliced with the wire row of the wire saw can be extracted from the wire row with a simple structure without a negative influence on its slicing surface.
