Patent ID: 8534275

Claim:
A wire saw device comprising: a group of multiple wires suspended in parallel to one another in a cutting side thereof, over plural rollers disposed separate from each other, so as to be capable of running in a direction orthogonal to the roller shaft direction; a work holding portion for holding a work and capable of moving in a direction of pushing the work with respect to the multiple wires; a nozzle for supplying slurry to the group of multiple wires from at least a position on the upperstream side in the running direction of the multiple wires, with respect to a path along which the work is pushed into the wires; and a slurry blocking plate, extending in the direction along which the multiple wires are aligned in parallel to one another, and pivotably fixed at a base point at least on the upperstream side in the running direction of the multiple wires with respect to the path and above the multiple wires, such that the slurry blocking plate falls, around the base point, on the work in the direction of pushing the work with respect to the multiple wires.
