Method for slicing workpiece

摘要

The present invention is a method for slicing a workpiece into wafers by pressing a cylindrical workpiece held with a workpiece holder against a wire row formed by a wire spirally wound between a plurality of wire guides and making the wire travel while supplying a slurry to a contact portion between the workpiece and the wire, wherein the workpiece is sliced with an axis direction of the workpiece inclined with respect to a plane formed by the wire row, after the workpiece is inclined in such a manner that a side far from the wire row plane is a side where the wire guides are to be axially expanded. As a result, there is provided a method for slicing that enable wafers having a good Warp shape to be obtained by precisely slicing a workpiece with a wire saw.
