1. A method for slicing a workpiece with a wire saw which includes a wire row formed by winding a fixed abrasive grain wire having abrasive grains secured to a surface thereof around a plurality of grooved rollers, the method comprising feeding a workpiece to the wire row for slicing while allowing the fixed abrasive grain wire to reciprocatively travel in an axial direction thereof, thereby slicing the workpiece at a plurality of positions aligned in an axial direction of the workpiece simultaneously,
wherein the method comprises:
supplying a coolant for workpiece slicing onto the wire row when the workpiece is being sliced with the fixed abrasive grain wire; and
supplying a coolant for workpiece drawing, which is different from the coolant for workpiece slicing and has a higher viscosity than the coolant for workpiece slicing, onto the wire row when the workpiece is drawn out from the wire row after the slicing of the workpiece.
