METHOD FOR SLICING WORKPIECE

摘要

A method for slicing workpiece reusing a wire used for previous slicing of a workpiece to slice a subsequent workpiece by which the workpiece is pressed against a wire row and sliced, the wire row being formed of the wire spirally wound between a plurality of wire guides and travels in an axial-direction, where wire tension at the time of slicing the workpiece is set to a value in the range of 87 to 95% of wire tension in the previous slicing of the workpiece, a new wire supply amount at the time of slicing the workpiece is set to a value in the range of 125% or more of a new wire supply amount in the previous slicing of the workpiece, and the wire is reused to slice the subsequent workpiece.

1. A method for slicing workpiece reusing a wire used for previous slicing of a workpiece to slice a subsequent workpiece in the slicing of the workpiece by which the workpiece is pressed against a wire row and the workpiece is sliced, the wire row being formed of the wire that is spirally wound between a plurality of wire guides and travels in an axial direction,
wherein wire tension at the time of slicing the subsequent workpiece is set to a value in the range of 87 to 95% of wire tension in the previous slicing of the workpiece, a new wire supply amount at the time of slicing the subsequent workpiece is set to a value in the range of 125% or more of a new wire supply amount in the previous slicing of the workpiece, and the wire is reused to slice the subsequent workpiece.
