PURPOSE: To enable a device to accurately perform its work while work efficiency can be improved, in the wire saw device. CONSTITUTION: A single wire 5 is helically wound to a plurality of machining rollers 3, 4. By rotating the machining rollers 3, 4, the wire 5 is made to run, to apply cutting work to a workpiece 10. The first detecting means, detecting a condition that cutting can be started against the workpiece 10, is constituted of the wire 5, workpiece 10, etc., and the second detecting means, detecting a condition that cutting is completed, is constituted of the wire 5, supporting plate, etc. |
